▼ Developing electric vehicles is widely considered as a direct approach to resolve the energy and environmental challenges faced by the human race. As one of the most promising power solutions to electric cars, the
lithium ion battery is expected to achieve better performance, durability and safety. Fracture induced by lithiation and deliathiation stress has been identified as a major mechanism that leads to capacity loss and performance degradation.
This work aims to shed light on the thermo-mechanical behavior of
lithium ion battery electrodes. It presents a single particle model of random lattice spring elements coupled with solid phase Li-
ion diffusion under active temperature effects. The thermal features are realized by solving a lumped heat conduction equation and by including temperature dependent parameters. This model combined with a typical equivalent-circuit model is used to predict the impedance response of electrode particles.
The fracture generation increases as the temperature decreases. However, the diffusion induced fracture is found to be proportional to the current density and particle sizes. Simulations under realistic driving conditions show that the fraction of particle damage is determined by the highest current density drawn from the
battery. A 3D phase map of fracture damage is presented.
The transit fracture growing process reveals a saturation phenomenon where the fraction of damage increases to a threshold value and then stabilizes. This is observed both during single discharging processes and in multiple cycle simulations. In the multicycle analysis, the charging process following the initial discharging leads to a ???re-saturation??? where the fracture experiences a second increase and then stops growing ever after.
The impedance study suggests that the generation of fracture leads to increase in impedance response of electrode particles. The calculated impedance results are found to be directly related to current density and particle size but drops with increasing temperatures.

▼ This thesis presents experimental measurements and
modeling of multi-scale collective behaviors characteristics of
hierarchical interfaces in
lithium-
ion batteries (LIBs) during
cycling. Two interfacial mechanisms are introduced: One is in-plane
sliding between lithiated electrodes (a-SiLix) and current
collectors (Cu). The other is normal contact between the internal
interfaces of pouch
battery cells. To estimate the interfacial
properties at a-SiLix//Cu interfaces, a new apparatus, named
“Self-Adjusting Liquid Linnik Interferometer (SALLI)”, has been
invented to perform in situ whole field deformation measurements
with µm resolution in lateral direction and nm resolution in
out-of-plane direction. Our result clearly demonstrates Li
segregation at the interface initially which leads to 200 µm
shrinkage of the Si film in the first cycle due to relaxation of
residual tensile stress. A mechanical model system, plate bending
distribution sensor (PBDS), which incorporates substrate bending
and interfacial sliding in its calibration has been developed. By
bridging the deformation estimated from PBDS and that measured from
the SALLI experiment, the interfacial properties are extracted
quantitatively. The critical energy release rate is estimated as
0.075 J/m2 and 0.34 J/m2 for the receding and growing shear crack
fronts respectively. A remarkable discovery is that the interfacial
shear strength of the actively segregating
lithium at the interface
is measured only 1.15 kPa. It is due electro-chemically active
lithium-
ion segregation process that allows slip processes of
hopping through a series of meta-stable atomic configurations.
Finally, two sets of in situ experiments have been performed and a
mechanical model has been developed to explain the internal contact
mechanism and its relationship with interface bubble-gas evolution.
Through these techniques, the degradation mechanism of the pouch
cells are explained. It shows that applying 4–5 psi prestressed
pressure to the cell can better control the bubble-gas formation
and increase the electrode contact area. Therefore, the
battery
life is efficiently elongated. It is hoped that the thesis work can
contribute to optimal design of
battery cells and maximize cell
capacity and life of LIBs.

▼ Advances in synthesis and processing of nanocarbon
materials, particularly graphene, have presented the opportunity to
design novel Li-
ion battery (LIB) anode materials that can meet the
power requirements of next-generation power devices. This thesis
presents three studies on electrochemical behavior of
three-dimensional (3D) nanostructured anode materials formed by
pure graphene sheets and graphene sheets coupled with conversion
active materials (metal oxides). In the first project, a
microgel-templated approach for fabrication of 3D macro/mesoporous
reduced graphene oxide (RGO) anode is discussed. The mesoporous 3D
structure provides a large specific surface area, while the
macropores also shorten the transport length of Li ions. The second
project involves the use of a novel magnetic field-induced method
for fabrication of wrinkled Fe₃O₄@RGO anode materials. The applied
magnetic field improves the interfacial contact between the anode
and current collector and increases the stacking density of the
active material. The magnetic field treatment facilitates the
kinetics of Li ions and electrons and improves electrode durability
and the surface area of the active material. In the third project,
poly (methacrylic acid) (PMAA)-induced self-assembly process was
used to design super-mesoporous Fe₃O₄@RGO anode materials and their
electrochemical performance as anode materials is also
investigated. To establish correlations between electrode
properties (morphological and chemical) and LIB performance, a
variety of techniques were used to characterize the samples. The
significant improvement in LIB performance of the 3D anodes
mentioned above is largely attributed to the unique properties of
graphene and the resulting 3D architecture.

▼ Plug-in hybrid electric vehicles (PHEVs) represent an advanced vehicle technology with the potential to displace petroleum consumption with energy generated on the US electric grid. While many benefits have been associated with the increased electrification of the US vehicle fleet, concerns over
battery lifetime and replacement costs remain an obstacle to widespread PHEV adoption. In order to accurately determine the lifecycle cost of PHEVs, assessment studies must make use of informed assumptions regarding
battery degradation and replacement. These assumptions should approach end-of-life (EOL) metrics not only in terms of pack level degradation but also loss of vehicle efficiency and performance in order to accurately represent consumer incentive for
battery replacement.
Battery degradation calculations should also remain sensitive to the range of ambient conditions and usage scenarios likely to be encountered in the US market. Degradation resulting from a single duty cycle has the potential to misrepresent
battery life distributions for the US fleet. In this study, the sensitivity of PHEV lifecycle cost to the
battery replacement assumption is explored to underscore the need for an improved understanding of PHEV
battery EOL conditions. PHEV specific
battery test results are presented to evaluate the ability of industry standard life test procedures to predict
battery degradation in PHEVs. These test results are used as inputs to a vehicle simulation program to understand changes in efficiency and performance with respect to
battery degradation using a light commercial vehicle simulated as a blended-mode capable, parallel PHEV20. A predictive
battery degradation model based on empirical data is used to explore sensitivity of
battery wear to various parameters including design variables, ambient conditions, and usage scenarios. A distribution of expected wear rates for a light-duty, midsize passenger vehicle modeled as a series PHEV35 is presented to highlight the uncertainty associated with
battery life
subject to US ambient conditions and driving distributions. The results of this study show that active management of PHEV
battery degradation by the vehicle control system can improve PHEV performance and fuel consumption relative to a more passive baseline. Simulation of the PHEV20 throughout its
battery lifetime shows that
battery replacement will be neither economically incentivized nor necessary to maintain performance. The spectrum of climate and usage conditions PHEVs are expected to face in the US market suggest that the assumption of a single average ambient condition for
battery wear calculations may not be representative of observed behavior in the fleet. These results have important implications for techno-economic evaluations of PHEVs which have treated
battery replacement and its costs with inconsistency.

▼ Lithium-
ion based batteries are the most energy and power dense rechargeable batteries currently available. However, to operate within safety limits
battery voltages, currents, and temperatures must be monitored throughout the charge-and-discharge cycle.
Battery Management Systems (BMS) monitor, report, or equalize the cell voltages of large packs to ensure operation within safety limits and to maintain balanced cells within the pack. For large
Lithium-
ion series packs, monitoring two or more cells in series instead of monitoring individual cells can reduce the size, weight, and complexity of a BMS, which is often desirable to strict space, weight, and reliability requirements. Monitoring and balancing every cell is desirable because when the
battery pack is charged all of the cells will be charged to the same voltage and if an individual cell dropped below a certain voltage on discharge, the load could be disconnected from the pack. By monitoring multiple cells and controlling the current limits of the pack, a small amount of resolution is lost but the system can still function safely.

▼ The performance of advanced energy storage devices is
intimately connected to the designs of electrodes. To enable
significant developments in this research field, we need detailed
information and knowledge about how the functions and performances
of the electrodes depend on their chemical compositions,
dimensions, morphologies, and surface properties. This thesis
presents my successes in synthesizing and characterizing electrode
materials for advanced electrochemical energy storage devices, with
much attention given to understanding the operation and fading
mechanism of
battery electrodes, as well as methods to improve
their performances and stabilities. This dissertation is presented
within the framework of two energy storage technologies:
lithium
ion batteries and
lithium oxygen batteries. The energy density of
lithium ion batteries is determined by the density of electrode
materials and their
lithium storage capabilities. To improve the
overall energy densities of
lithium ion batteries, silicon has been
proposed to replace
lithium intercalation compounds in the
battery
anodes. However, with a ~400% volume expansion upon fully
lithiation, silicon-based anodes face serious capacity degradation
in
battery operation. To overcome this challenge,
heteronanostructure-based Si/TiSi2 were designed and synthesized as
anode materials for
lithium ion batteries with long cycling life.
The performance and morphology relationship was also carefully
studied through comparing one-dimensional and two-dimensional
heteronanostructure-based silicon anodes.
Lithium oxygen batteries,
on the other hand, are devices based on
lithium conversion
chemistries and they offer higher energy densities compared to
lithium ion batteries. However, existing carbon based electrodes in
lithium oxygen batteries only allow for
battery operation with
limited capacity, poor stability and low round-trip efficiency. The
degradation of electrolytes and carbon electrodes have been found
to both contribute to the challenges. The understanding of the
synergistic effect between electrolyte decomposition and electrode
decomposition, nevertheless, is conspicuously lacking. To better
understand the reaction chemistries in
lithium oxygen batteries, I
designed, synthesized, and studied heteronanostructure-based
carbon-free inorganic electrodes, as well as carbon electrodes
whose surfaces protected by metal oxide thin films. The new types
of electrodes prove to be highly effective in minimizing parasitic
reactions, reducing operation overpotentials and boosting
battery
lifetimes. The improved stability and well-defined electrode
morphology also enabled detailed studies on the formation and
decomposition of Li2O2. To summarize, this dissertation presented
the synthesis and characterization of inorganic nanostructured
materials for advanced energy storage. On a practical level, the
new types of materials allow for the immediate advancement of the
energy storage technology. On a fundamental level, it helped to
better understand reaction chemistries and fading mechanisms…

▼ Inspired by the discovery of the photocatalytic phenomenon in splitting water, enormous efforts have been devoted to the research of TiO2 materials. This has led to various applications ranging from photovoltaics and photocatalysis to batteries and sensors, which can be roughly divided into ‘energy’ and ‘environmental’ categories. In general, the effectiveness in the practical applications depend not only on the intrinsic properties of the TiO2 material, but also on modification to the material, including composition, morphology, and the compositional modification.
As a photocatalyst, TiO2 is a wide band gap semiconductor (3.0-3.2 eV) that can be used to decompose organic compounds under ultraviolet light irradiation. An efficient strategy to extend the light response to the visible range and thus improve photocatalytic activity is by designing a heterojunction semiconductor. In this thesis pristine anatase TiO2 microspheres were used to prepare mesoporous TiO2/g-C3N4 microspheres via a nano-coating procedure followed by calcination, where the porous TiO2 acts as the active supporting scaffold and g-C3N4 as the visible light sensitizer. The composite microspheres were 8.5 folds more active in degrading phenol under visible light irradiation than mesoporous g-C3N4. Furthermore, starting with mesoporous TiO2 hollow microspheres, mesoporous brookite/anatase TiO2/g-C3N4 hollow microspheres were prepared via a facile nanocoating procedure that showed mixed phases of brookite (48 %), anatase (44 %), and rutile (8 %), incorporated with a g-C3N4 coating layer. The mesoporous hollow microspheres exhibited a unique hollow shell morphology of packed TiO2/g-C3N4 nanosheets, and a remarkable 5-fold increase in degrading phenol under visible light irradiation compared to mesoporous g-C3N4.
Besides visible light photocatalysis, TiO2 can be used as an anode material for lithium-ion batteries, as it shows good gravimetric performance (336 mAh g-1) and excellent cyclability. To overcome the poor rate behaviour, slow lithium-ion diffusion, and high irreversible capacity decay, TiO2 nanomaterials with tuned compositions and morphologies are being investigated. Here, a promising TiO2 material has been prepared that comprises a mesoporous ‘yolk-shell’ spherical morphology in which the core is anatase TiO2 and the shell is TiO2(B). The electrochemical results indicate high specific reversible capacity at moderate current (330.0 mAh g-1) and cyclability (98 % capacity retention after 500 cycles).
Lithium-sulphur batteries have attracted considerable attention as they have high specific capacity (1675 mAh g-1) and the abundance of sulphur, makes them one of the more promising next-generation battery technologies. However, commercialization of LSBs has generally been hampered by low sulphur utilization and poor long-term cyclability. These issues can be addressed, in part, by producing cathodic additives to encapsulate sulphur and polysulphides during the charge/discharge process. Mesoporous Magnéli Ti4O7 microspheres were prepared…

▼ The exploration of functional materials to store renewable, clean, and efficient energies for electric vehicles (EVs) has become one of the most popular topics in both material chemistry and electrochemistry. Rechargeable lithium batteries and fuel cells are considered as the most promising candidates, but they are both facing some challenges before the practical applications. For example, the low discharge capacity and energy density of the current lithium ion battery cannot provide EVs expected drive range to compete with internal combustion engined vehicles. As for fuel cells, the rapid and safe storage of H2 gas is one of the main obstacles hindering its application. In this thesis, novel mesoporous/nano functional materials that served as cathodes for lithium sulfur battery and lithium ion battery were studied. Ternary lithium transition metal nitrides were also synthesized and examined as potential on-board hydrogen storage materials for EVs.
Highly ordered mesoporous carbon (BMC-1) was prepared via the evaporation-induced self-assembly strategy, using soluble phenolic resin and Tetraethoxysilane (TEOS) as precursors and triblock copolymer (ethylene oxide)106(propylene oxide)70(ethylene oxide)106 (F127) as the template. This carbon features a unique bimodal structure (2.0 nm and 5.6 nm), coupled with high specific area (2300 m2/g) and large pore volume (2.0 cm3/g). The BMC-1/S nanocomposites derived from this carbon with different sulfur content exhibit high reversible discharge capacities. For example, the initial capacity of the cathode with 50 wt% of sulfur was 995 mAh/g and remains at 550 mAh/g after 100 cycles at a high current density of 1670 mA/g (1C). The good performance of the BMC-1C/S cathodes is attributed to the bimodal structure of the carbon, and the large number of small mesopores that interconnect the isolated cylindrical pores (large pores). This unique structure facilitates the transfer of polysulfide anions and lithium ions through the large pores. Therefore, high capacity was obtained even at very high current rates. Small mesopores created during the preparation served as containers and confined polysulfide species at the cathode. The cycling stability was further improved by incorporating a small amount of porous silica additive in the cathodes.
The main disadvantage of the BMC-1 framework is that it is difficult to incorporate more than 60 wt% sulfur in the BMC-1/S cathodes due to the micron-sized particles of the carbon. Two approaches were employed to solve this problem. First, the pore volume of the BMC-1 was enlarged by using pore expanders. Second, the particle size of BMC-1 was reduced by using a hard template of silica. Both of these two methods had significant influence on improving the performance of the carbon/sulfur cathodes, especially the latter. The obtained spherical BMC-1 nanoparticles (S-BMC) with uniform particle size of 300 nm exhibited one of the highest inner pore volumes for mesoporous carbon nanoparticles of 2.32 cm3/g and also one of the highest…

▼ Graphene, a two-dimensional honeycomb carbon layer, has drawn intensive attention as a promising electrode material for rechargeable batteries and supercapacitors due to its high electrical conductivity as well as chemical and physical stability. Recent progress of large-scale synthesis of graphene oxide (GO) from graphite has boosted more investigations for the conversion of GO to graphene. For energy storage applications, the role of graphene can be largely categorized into two groups: A) A inactive, supporting component for the build-up of composites with various active materials and B) Graphene itself as an active material for charge storage. Graphene, as a supporting component, is not involved electrochemical reactions to store charge or contribute to the amount of charge storage with very limited capacity or capacitance. Regarding this role, graphene-encapsulated submicron Si and two-dimensional functional carbon (TDFC) synthesis using graphene-template were studied in tow sub-themes. In the graphene-encapsulated submicron Si study, submicron Si particles were recovered from Si waste and utilized as a high-performance anode material for LIBs. From the versatile hydrothermal assembly, submicron Si particles were securely coated with graphene. The submicron Si/graphene composite exhibited good cycling stability, showing a capacity retention of 84% at the 100th cycles. In the study of the TDFC, ultrathin TDFC (thickness of 10~20nm) with abundant oxygen functional groups was prepared by GO-template assisted hydrothermal reaction of glucose. During the hydrothermal reaction, GO acted as a substrate for depositing hydrocarbon on its surface. Due to the presence of oxygen functional group on the surface of GO and the planar morphology of GO, the prepared 2D thin film enables more efficient utilization of the redox reactions compared to the conventional carbon sphere, showing a key approach to effectively utilize their redox-reactions.
In addition, graphene actively participates in charge storage and thus graphene can be identified as an active material. It is known that an irreversible restacking of GO sheets during electrode preparation has limited the accessible surface area (ASA) to store ions, resulting in a low gravimetric capacity of ~100 mAh/g. In this section, three subtopics of graphene as the active material for charge storage were investigated; A) Crumpled graphene oxide cathode for
lithium-
ion battery (LIB). B) Stacking-controlled cabbage-like graphene electrodes for supercapacitor. C) Crumpled graphene anode for Sodium-
ion battery. The second group is mostly associated with the restacking issue of GO and graphene. In the study of crumpled graphene oxide cathode, the crumpled graphene oxide was employed as cathode material for LIB. The crumpled graphene oxide has an aggregation-resistive characteristic and 3D ball-like morphology. The crumpled graphene oxide showed that the effective utilization of the surface redox reactions with enhanced electrochemical energy storage such as high rate-capability,…

▼ Nowadays, the fast-increasing energy demand for efficient, sustainable and environmentally-friendly energy storage devices remains a significant and challenging issue.
Lithium ion batteries (LIBs) have been widely used as commercial energy devices in portable electronics and also shown great promise in upcoming large-scale applications due to their advantages of environmental safety, efficiency in energy delivering and light weight. However, due to their limited capacity, energy densities and cycle ability, LIBs still need further improvement to expand their applications to a larger field, especially electric vehicle (EVs) and hybrid electric vehicles (HEVs), in which energy storage devices with large capacity and high energy density are urgently required. The increasing demand for their emerging applications in hybrid electric vehicles (HEVs) and electric vehicles (EVs) requires us to develop LIBs with higher energy density and power density. Significant improvements have been achieved on researching materials with high capacity to replace current commercial cathode material (LiCoO
2) and anode material (graphite). In this report, we introduce several research works on novel design and synthesis of nanostructured electrode materials with high performance for
lithium-
ion batteries.
Our work concentrates on boosting electrochemical performance of both cathode and anode materials for
lithium ion batteries. The first project is focused on synthesis of KFe

ion-exchange promoted phase transition. The spinel-structured LHMNCO TBA shows improved capacity retention and improved rate capability as cathode for
lithium ion batteries. In addition, we also developed various several strategies to improve the performance of anode materials. Coral-like SnO

The improve anode performance is attributed to the synergistic effect of integrated crystal and amorphous components as well as the unique interwoven heterostructure.

▼ The field of energy storage has improved drastically within the last two decades. Batteries of various chemistries have been relied on to provide energy for numerous portable electronic devices. Lithium-ion cells, when compared to other chemistries have been known to provide outstanding energy-to-weight ratios and exhibit low self-discharge when not in use [1]. The aforementioned benefits in conjunction with decreasing costs have made lithium-ion cells an exceptional choice for use in electrical vehicles (EVs). Battery Management Systems (BMS) in EVs are responsible for providing estimates for values that are indicative of the battery pack’s present operating condition. The current operating condition could be described by State of Charge, power fade, capacity fade and various other parameters [2]. Importantly, it is essential for the estimation technique to adjust to fluctuating cell characteristics as the cell ages, in pursuance of having available accurate estimates for the life time of the pack. In order for the estimation technique to properly estimate the desired quantities, a mathematical model capable of capturing cell dynamics is desired. There are various proposed methods recommended for mathematically modeling a cell, namely equivalent Circuit modeling, electro-chemical modeling and impedance spectroscopy. Consequently, in order to ensure mathematical models are accurate and further to have the ability to compare the proposed models, it is essential to have available data gathered from a given cell at specific operating conditions. This Master’s thesis outlines the development of a lithium-ion cell tester that is capable of controlling, monitoring and recording parameters such as current, voltage and temperature. The Dual capability of obtaining data from standardized cell tests as well as high frequency cell tests is fascinating and intriguing. As this capability holds the possibility of reducing cost otherwise spent on man hours and equipment which are both paramount in any industrially automated process.

▼ Lithium-
ion batteries have been used extensively over
the past two decades in the portable consumer electronics industry.
More recently, Li-
ion batteries have become candidates for much
larger-scale applications such as electric vehicles and energy grid
storage, which impose much more stringent requirements on
batteries, especially in terms of cell lifetime. In order to
develop batteries with improved lifetimes, a means of quickly and
accurately evaluating
battery life is required. The use of
coulombic efficiency (CE) is an important tool in this regard,
which provides a way to quantify parasitic reactions occurring
within the cell. As more stable
battery chemistries are developed,
the rates of parasitic reactions occurring in the cell become
reduced, and differences in CE among cells become increasingly
smaller. In order to resolve these differences, charger systems
must be developed which can measure CE with increased precision and
accuracy. This thesis investigates various ways to improve the
precision and accuracy of CE measurements. Using the high-precision
charger (HPC) at Dalhousie University (built in 2009) as a starting
point, a new prototype charger was built with several modifications
to the design of the existing HPC. The effect of each of these
modifications is investigated in detail to provide a blueprint for
the development of next-generation charger systems. This prototype
charger shows greatly improved precision and accuracy, with CE
results that are approximately four times more precise than those
of the existing HPC and over an order of magnitude more precise
than high-end commercially available charger systems

▼ Metallic Tin is a promising anode material for
lithium ion batteries because of its high energy density, electrical conductivity and market availability. However, Tin based anodes typically experience limited cycle life resulting from extreme mechanical stress during lithiation. The mechanical stress leads to volumetric change and consequent unstable growth of solid electrolyte interface (SEI) during cycling. Nano-sizing is an effective way to reduce mechanical stress and prolong the cycle life of tin based electrode. However, small particle size means numerous difficulties in the fabrication process and might easily lead to agglomeration issues. In this study, free standing tin nanoparticles have been synthesized in-situ on 3D electrodes. Further, mechanically stable carbon based structural modifiers have also been employed to reinforce these electrodes. Best performing composite electrode delivered a high specific capacity of 917mAh/g and a capacity retention of greater than 66% after 150 cycles.

▼ New and innovative materials are needed to develop more effective batteries. Nanoscale materials such as graphite have unique properties only seen in the nano-regime that allow them to be used in the production of
lithium-
ion batteries. For example, because of its ability to conduct electricity, nano-scale graphite has been used in the anode of
lithium-
ion batteries, which has revolutionized the long-term use of medical devices, such as pacemakers and defibrillators. Interestingly, the graphite anode has a relatively low specific capacity per gram of ~372 mAh g-1, which limits the rate of charge available to these devices. The specific capacity of silicon, however, is ~11 times greater than that of graphite at ~4200 mAh g-1, which makes it a better choice as an anode material. Silicon is not presently used because of its fragility during the lithiation process. In this work, we demonstrate a robust nanoscale material synthesis inspired by the biomineralization process that the ocean-dwelling unicellular phytoplankton, diatoms, that they use to form their porous silicon structure. By maintaining the porous structure of diatoms from the conversion of silica to silicon, using a magnesiothermic reduction process, their structure can be used to enhance silicon’s strength during the lithiation process allowing the use of silicon’s higher specific capacity. This approach has the potential to implement silicon as an anode for
lithium-
ion batteries to enhance the longevity of present day applications.

▼ This thesis details electrical and physical measurements of pulsed laser deposition-applied thin film coatings of Alumina, Ceria, and Yttria-stabilized Zirconia (YSZ) on a LiNi0.5Mn0.3Co0.2O2 (NMC) cathode in a
Lithium ion battery. Typical NMC cathodes exhibit problems such as decreased rate performance and an opportunity for increased capacity exists by raising operation voltage beyond the electrolyte stability window. Very thin (~10 nm) coatings of stable oxides provide a pathway to solve both problems. As well, the electrochemical impedance spectra of the uncoated and coated cells were measured after different numbers of cycles to reveal the property variation in the cathode. Further understanding of the mechanism of rate performance enhancement and chemical protection by thin oxide coatings will continue to improve
battery capability and open up new applications.
Ceria-coated Li-NMC cells show the best capacity and rate performance in
battery testing. Through electrochemical impedance spectroscopy (EIS), the surface film resistance was found to remain stable or even drop slightly after repeated cycling at high voltage. CeO2 is proposed as a coating for
Lithium ion battery cathodes owing to its high chemical stability and the demonstrated but not yet well understood electrical conductivity. Alumina-coated cathode shows comparable performance as that of the uncoated cell in the early stage of the test, but through the course of testing the rate capability and recoverable capacity is improved. This is possibly due to Al2O3?s well-known abilities as HF scavenger and chemically inert nature. YSZ-coated cathode performs worse than the uncoated ones in terms of capacity, rate capability, and EIS-related figures of merit. The reason for the poor performance is not yet known, and repeatability tests are under way to verify performance. High voltage cycling reveals no obvious difference in irreversible loss between the coated or uncoated cells. The reason for the lack of distinction could be the relatively small percentage of surface coating compared to the thick doctor-blade processed cathode layer.

▼ Lithium ion battery systems are promising solutions to current energy storage needs due to their high operating voltage and capacity. Numerous efforts have been conducted to model these systems in order to aid the design process and avoid expensive and time consuming prototypical experiments. Of the numerous processes occurring in these systems, solid state transport in particular has drawn a large amount of attention from the research community, as it tends to be one of the rate limiting steps in
lithium ion battery performance. Recent studies have additionally indicated that purposeful design of
battery electrodes using 3D microstructures offers new freedoms in design, better use of available cell area, and increased
battery performance.
The following study is meant to serve as a first principles investigation into the behaviors of 3D electrode architectures by monitoring concentration and cycle behaviors under realistic operating conditions. This was accomplished using computational tools to model the solid state diffusion behavior in several generated electrode morphologies. Developed computational codes were used to generate targeted structures under prescribed conditions of particle shape, size, and overall morphology. The diffusion processes in these morphologies were simulated under conditions prescribed from literature.
Primary results indicate that parameters usually employed to describe electrode geometry, such as volume to surface area ratio, cannot be solely relied upon to predict or characterize performance. Additionally, the interaction between particle shapes implies some design aspects that may be exploited to improve morphology behavior. Of major importance is the degree of particle isolation and overlap in 3D architectures, as these govern gradient development and
lithium depletion within the electrode structures. The results of this study indicate that there are optimum levels of these parameters, and so purposeful design must make use of these behaviors.

▼ This thesis focuses on computationally efficient methods to solve the equations of the Doyle Fuller Newman electrochemical
battery model. The two methods used in this work are orthogonal projections to solve partial differential equations and the descriptor form to solve a system of differential algebraic equations. An orthonormal set of polynomials is required for the orthogonal projection method. Two sets of Legendre Polynomials are used, one that is orthonormal over the thickness of the
battery, and another over the radius of the solid electrode particles. The orthogonal projection method is then benchmarked against the finite difference method to assess the benefits and drawbacks. It is shown that the orthogonal projection method is computationally faster than the finite difference method with very little loss in accuracy. It can also be shown that the descriptor form not only simplifies the inclusion of the boundary conditions, but also increases the computational speed of the model.
Based on the knowledge that there is a computational benefit in using orthogonal projections in descriptor form, all five components of the Doyle Fuller Newman model are solved using orthogonal projections. The nonlinear components of the model are linearized at each time step. The
battery model is capable of running faster than real time while providing results similar to the manufacturer's data [1].

▼ There is an ever-growing demand for
Lithium-
Ion Batteries in a widespread series of applications, where
battery life and reliability are of key importance. There exist novel materials that are helping increase
battery reliability and life but there is a lack of environment friendly and cost-effective processing techniques that are used to produce such energy storage devices. Current processing techniques use N-methyl-2 pyrrolidone as a solvent for electrode slurry, which is expensive and has the potential to damage the environment, increasing the risk of cancer and reproductive toxicity. Therefore, there is a need to move towards a solvent that is environmentally friendly, cheap to produce and can serve as a potential replacement. In this work, the use of deionized water has been experimentally evaluated to create an electrode processing technique that could become an environmentally friendly and cost-effective technique to produce
Lithium-
Ion Batteries.
This study focuses on the concepts of
Lithium-
Ion Batteries and their current electrode processing techniques. The proposed Aqueous Processing technique for electrode manufacture is discussed in detail along with a discussion of challenges currently being faced in this area. A 1-D physics based drying model is also developed as part of this study that is based upon evaporation, diffusion and sedimentation.
My analysis has shown that the proposed Aqueous Processing can be implemented using low-cost preparation methods and deionized water. Drying temperature has an effect on the agglomeration of particles that could impact the electrochemical performance of the electrode. My analysis has also shown that an optimal amount of dispersant needs to be added to reduce the effect of agglomeration while maintaining good film adhesion. The results from the 1-D show that at a higher drying temperature a larger volume fraction is observed at the top surface of the electrode.

▼ Lithium ion batteries
have served as power sources for portable electronic
devices for the past two decades. To date, they have
employed polycrystalline microsized powder electrode
materials. However, many next-generation electronic
devices or wireless communication devices demand thin and
flexible electrodes with higher energy density than ever
before. Moreover, the large-scale potential lithium ion
battery applications, such as in electric vehicles,
(plug-in) hybrid electric vehicles, or energy storage
systems in smart grids, require batteries exhibiting high
rate capability, high power, and long cycle life. Due to
the advantages of nanostructured electrode materials,
i.e., high surface area, more lithium active sites, and
shorter lithium diffusion length, the electrochemical
performance of nanomaterial electrodes are more likely to
meet the specific requirements in the potential new
applications. In this doctoral work, various
nanostructured materials were synthesized, characterized
by different physical techniques and tested as potential
anode electrode materials for lithium ion batteries. The
nanomaterials include porous SnO2,
SnO2/C composite, one-dimensional
SnO2/carbon nanotube (CNT)
composite, SnO2 nanofibre,
SnO2/C composite nanofibre,
restacked MoS2,
MoS2/SnO2
composite, one-dimensional TiO2(B)
nanowire, three-dimensional TiO2
nanotube arrays, SnO2
nanocrystal/TiO2 nanotube array
composite, and nanosized polycrystalline
Li4Ti5O12.
Various nanostructured
SnO2 and
SnO2/C composites were prepared by
the molten salt, solvothermal, and electrospinning
techniques. The porous SnO2 and
SnO2/C nanocomposite prepared by
the molten salt method exhibit high surface area, giving
more contact area between the active material and the
electrolyte, as well as a decreased lithium diffusion
length. At the same time, the pores could accommodate the
volume expansion. Porous SnO2
electrode delivers a reversible capacity of 410 mAh
g-1 after 100 cycles in the
voltage range of 0.05-1.5 V, while the composite shows
better capacity retention (85.3 wt%) than bare
nano-SnO2 (64.8 wt%) after 100
cycles. SnO2/CNT composite
synthesized by the solvothermal method consists of a
conductive CNT core and SnO2
nanocrystals about 5 nm in size that are…

▼ Global efforts to reduce emissions and the need for improved energy storage for mobile power applications have stimulated extensive research on new battery technologies. Lithium-ion batteries have emerged as the principal technology for energy storage in electric vehicles, portable electronic devices, and grid storage; strongly driving demand for component materials. Nevertheless, substantial improvements in performance, safety and cost are required, creating a need for new technical solutions. Here, borates are investigated for the enhancement of energy storage. As confirmed by a deep exploration of the literature and further experimentation, borates show excellent potential as additives to graphite anodes to improve the properties of lithium-ion batteries.

▼ Crystals of LiFePO4 and related materials have recently received a lot of attention due to their very promising use as cathodes in rechargeable lithium ion batteries. This thesis studied the electronic structures of FePO4 and LiMPO4, where M=Mn, Fe, Co and Ni within the framework of density-functional theory. The ¯rst study compared the electronic structures of the LiMPO4 and FePO4 materials in their electrochemically active olivine form, using the LAPW (linear aug- mented plane wave) method [1]. A comparison of results for various spin con¯gura- tions suggested that the ferromagnetic con¯guration can serve as a useful approxima- tion for studying general features of these systems. The partial densities of states for the LiMPO4 materials are remarkably similar to each other, showing the transition metal 3d states forming narrow bands above the O 2p band. By contrast, in absence of Li, the majority spin transition metal 3d states are well-hybridized with the O 2p band in FePO4. The second study compared the electronic structures of FePO4 in several crys- tal structures including an olivine, monoclinic, quartz-like, and CrVO4-like form [2, 3]. For this work, in addition to the LAPW method, PAW (Projector Augmented Wave) [4], and PWscf (plane-wave pseudopotential) [5] methods were used. By care- fully adjusting the computational parameters, very similar results were achieved for the three independent computational methods. Results for the relative stability of the four crystal structures are reported. In addition, partial densities of state analyses show qualitative information about the crystal ¯eld splittings and bond hybridizations and help rationalize the understanding of the electrochemical and stability properties of these materials.

▼ Electric Vehicles (EVs) have gained acceptance as low or zero emission means of transportation. This thesis deals with the design of a battery cell testing platform and Lithium-Ion (Li-Ion) battery modeling for EVs. A novel regenerative cell testing platform is developed for cell cycling applications. A 300 W - 5 V cell cycler consisting of a buck and a boost converter is designed.
Furthermore, a novel battery modeling approach is proposed to accurately predict the battery performance by dynamically updating the model parameters based on the battery temperature and State of Charge (SOC). The comparison between the experimental and the model simulation results of an automotive cell under real-world drive-cycle illustrates 96.5% accuracy of the model. In addition, the model can be utilized to assess the long-term impact of battery impedance on performance of EVs under real-world drive-cycles.

▼ The Li-ion field of battery research has in the latest decades made substantial progress and is seen to be the most promising battery technology due to the high volume and specific energy densities of Li-ion batteries. However, in order to achieve a battery capable of competing with the energy density of a combustion engine, further research into new electrode materials is required. As the cathode materials are the limiting factor in terms of capacity, this is the main area in need of further research. The introduction of 3-D electrodes brought new hope as the ion transportpath is decreased as well as an increased electrode area leading to an increased capacity. This thesis work has focused on the development of aluminium 3-D current collectors in order to improve the electrode area and shorten the Li-ion transportpath. By using a template assisted electrodeposition technique, nanorods of controlled magnitude and order can be synthesized. Furthermore, the electrodeposition brings excellent possibilities of upscaling for future industrial manufacturing of the batterycells. A polycarbonate template material which showed interesting properties,was used in the electrodeposition of aluminium nanorods. As the template pores were nonhomogeneously ordered a number of nonordered nanorods were expected to arise during the deposition. However, a surplus of nanorods in reference to the template pores was acquired. This behavior was investigated and a hypothesis was formed as to the mechanism of the nanorod formation. In order to achieve acomplete cathode electrode, a coating of an ion host material on the nanorods isneeded. Due to its high capacity and voltage, vanadium oxide was selected. Based on previous work with electrodeposition of V2O5 on platinum, a series of experiments were performed to mimic the deposition on an aluminium sample. Unfortunately, the deposition was unsuccessful as the experimental conditions resulted in aluminium corrosion which in turn made deposition of the cathode material impossible. The pH dependence of the deposition was evaluated and the conclusion was drawn, that electrodeposition of vanadium oxide on aluminium is not possible using this approach.

▼ In order to replace diesel energy in the transportation sector as well as to reduce the emission of green house gases (GHGs) and avoid air pollution for a sustainable future, electrification of vehicles is one of the most popular topics today. Plug-in hybrid electric vehicle (PHEV) technology is a promising technology for electrification of automobiles. It uses both internal combustion engine and electric motor for propulsion. The battery pack that propels the electric machine can be recharged from grid electricity and from kinetic energy converted from regenerative braking. In this thesis, field test data from a Volvo V70 prototype in a 2010 study by Volvo and Vattenfall (ETC, Volvo, Vattenfall, 2010) was analyzed with Matlab to give a better understanding of the usage of PHEVs and the performance of lithium-ion battery. Several conclusions were obtained in this thesis from the analyzed data. It was found that average and maximum driving speed in Diesel Mode is faster than that in Electric Mode. Different drivers had different preference of driving speed. Driving distance vary in different months; longer distance was running under Diesel Mode; A considerable number of 370 kg carbon dioxide emission was saved by using electric energy instead of diesel energy for the studied car during one year. Battery performance in cold temperature conditions needs to be considered and the vehicle was switched to Diesel Mode from Electric Mode when SOC falls below 30%.

▼ In the foreseeable future, global energy demand is expected to rapidly increase as a result of the swelling population and higher standards of living. Current energy generation and transportation methods predominantly involve the combustion of non-renewable fossil fuels, and greenhouse gas emissions from these processes have been shown to contribute to global climate change and to be detrimental to human and environmental health. To satisfy future energy needs and to reduce greenhouse gas emissions, the advancement of renewable energy generation and electric vehicles is important. The proliferation of intermittent renewable energy sources (such as solar and wind) and electric vehicles depends upon reliable, high-capacity energy storage to serve the practical needs of society. The present-day
lithium-
ion battery offers excellent qualities for this purpose; however, improvements in the capacity and cost-effectiveness of these batteries are needed for further growth. As an anode material, silicon has exceptionally high theoretical capacity and is an earth-abundant, low-cost option. However, silicon also suffers from poor conductivity and long-term stability, prompting many studies to investigate the use of additive materials to mitigate these issues. This thesis focuses on the improvement of silicon anode performance by using a nanoparticulate copper additive to increase material conductivity and an inexpensive, industry-compatible anode fabrication process. Three main fabrication processes were explored using differing materials and heat treatment techniques for comparison. Anodes were tested using CR2032 type coin cells. The final anodes with the most-improved characteristics were fabricated using a high-temperature heating step for the anode material, and an additional batch was formed to test the viability of the copper additive functioning as a full substitute for carbon black, which is the traditional choice of conductive additive for electrode materials. Anodes materials were characterized using a variety of techniques including scanning electron microscopy (SEM), electron dispersive spectroscopy (EDS), inductively coupled plasma optical emission spectrometry (ICP-OES), Raman spectroscopy, and X-ray diffraction (XRD) to evaluate surface qualities and material content. Electrochemical techniques including electrochemical impedance spectroscopy (EIS) and charge/discharge cycling were also used to determine the conductivity and functional behavior of the anode materials. Anodes from the final experimental study achieved initial capacities of 309 mA/g and 957 mA/g for the silicon-only control and silicon with copper additive anodes, respectively, demonstrating an over 300% increase in specific capacity. Si-Cu (NC) anodes also showed superior performance over control anodes with an initial capacity of 775 mA/g. For all three anodes, high efficiencies of over 96% were achieved for the testing duration of 100 cycles and reached near or over 99% in final cycles. Results also show a significant decrease…

▼ Ionic Liquids (ILs) are organic salts
comprised entirely of organic cations and organic/inorganic anions.
ILs are recognized as “designer solvents”“ due to their composition
and the endless combinations of anions and cations. ILs have
various outstanding properties, such as negligible vapor pressure,
excellent thermal and chemical stability, nonflammability,
nonvolatility, etc. These unique attributes explains the interest
in ILs, which has been growing since the 1930s, for a wide variety
of applications, including gas/liquid separation, chemical
reaction, lubrication and electrochemical devices. Even though
there are many thousands of possible combinations of anions and
cations for ILs design, the choice/selection of cations and anions
commercialized in electrochemical devices is much less diverse due
to strict industrial standards. Most
electrolytes currently in commercial use are volatile and flammable
organic solvents, so safety is a serious concern that must be
addressed. The focus of this thesis is to develop halogen-free
ionic liquid electrolytes to overcome the drawbacks of conventional
organic solvents used in
lithium-
ion batteries and to gain further
insight into the influence of structure on physicochemical and
electrochemical properties from both theoretical and practical
perspectives. This thesis describes the effects of the experimental
temperature, the structure of the cation and anion, and the
concentration of
lithium salt on the properties of ILs. More
specifically, physicochemical property measurements cover density,
viscosity and diffusivity, and electrochemical property
investigation includes conductivity, electrochemical window, Walden
plot behavior and ionicity. Understanding these effects can not
only guide practical development of safer and more liable
electrolytes for
lithium-
ion batteries, but also pave the way for
future theoretical investigation of ILs as electrolytes for
lithium-
ion battery applications.

▼ In this work, we focused on different applications of polymer in
Lithium-
ion battery electrodes, with an emphasis in structure engineering of polymers in order to provide a better understanding in the fundamental relationship between polymer structure, electrode composition,
battery properties and performance. We first studied self-doped polymeric binder, PFP, in V2O5 cathodes. This fully water-processable, thermally annealed hybrid electrode shows steady cycling performance even when it is annealed at 400°C. We believe this is because the addition of 5 wt% PFP as binder helps suppress the crystallization of V2O5 xerogel and avoid the disruption of its layered structure. Then we discussed using conjugated polymer PNDI-T2EG as the active materials in electrode. We demonstrated that modification of conjugated polymer side-chains had a significant impact on the electrochemical performance of nano-composite electrodes, in particular enabling excellent performance at high charge-discharge rates. By attaching OEG side-chains, electrodes demonstrate exceptional rate performance at high charge-discharge rate, high mass loading, and high active material content. As a continued study, we look at a series of PNDI-based polymer with different ratios of OEG side-chains. All these works help to demonstrate that structure engineering of polymers is an efficient strategy when researching for the next better materials used for
battery development.

▼ The thriving energy-storage market has been motivating enormous efforts to advance the state-of-art
lithium-
ion batteries. The development of cathode materials, in particular, holds the key to realizing the high-energy-density and low-cost promise. Among the insertion-reaction cathodes currently in play, the layered oxides, especially the LiNiO₂-based high-Ni type, are being intensively pursued as one of the most promising candidates. However, the high-Ni layered oxides inherently encounter a trade-off between capacity and stability - the higher the capacity contributed by the higher Ni content, the worse the electrochemical cyclability. This dissertation focuses on improving the stability of high-Ni layered oxide cathodes through multiple effective approaches. First, a practical doping method is presented by incorporating a small dose of Al into the layered structure, which significantly improves the electrochemical performance of the cathode. It reveals that Al-incorporation greatly enhances the stability of cathode-electrolyte-interphase (CEI) due to the modified cathode electronic structure. Furthermore, in-situ X-ray diffraction provides an operando evidence for the reduced lattice distortions during cycling with Al-incorporation. Second,
lithium bis(oxalate) is employed as an effective electrolyte additive to improve the electrode-electrolyte-interphase stability. The well-tuned electrode-electrolyte interphase is featured with excellent robustness against electrochemical abuse. Moreover, the correlation between cathode-surface chemistry and anode-electrolyte interphase is revealed by studying the interphases at atomic level. Third, by constructing a dual-functional binder framework with a conductive polymer polyaniline, the high-Ni layered oxide cathodes exhibit significantly improved cyclability. This new binder framework not only promotes the rate performance even at low temperatures, but also effectively scavenges the acidic species in the electrolyte through a protonation process. Hence the cathode-surface reactivity is greatly suppressed and the rock-salt phase propagation into the bulk structure is considerably alleviated. Finally, in comparing with the state-of-art cathode (LiNi [subscript 0.8] Co [subscript 0.1] Mn [subscript 0.1] O₂), the interphasial and structural evolution processes of high-Ni layered oxides (LiNi [subscript 0.94] Co [subscript 0.06] O₂) are systematically investigated over the course of their service life (1,500 cycles). By applying advanced analytical techniques (e.g., Li-isotope labeling and region-of-interest method), the dynamic chemical evolution on the cathode surface is revealed with spatial resolution, and the correlation between lattice distortion and cathode-surface reactivity is established for the first time.

▼ As the power demands of mobile technologies continue to increase,
lithium-
ion batteries are needed with greater power and energy density. Silicon anodes offer an alternative to commercial graphite with much greater gravimetric and volumetric Li storage. Si nanowires are particularly compelling anode materials because they provide short Li diffusion paths due to their narrow diameter combined with long continuous paths for electron transport down their length. To achieve reasonable
battery performance in Si nanowire anodes, conductive carbon particles must be added to provide sufficient electrical conductivity through the anode layer. This lowers the capacity of the anode, but more importantly the carbon particles can segregate in the electrode layer during processing or as a result of mechanical stresses during cycling, leading to unreliable performance. Better performance can be achieved by altering the structure of the Si nanowire to improve electrical conductivity. Si nanowires with a conductive carbon coating were synthesized in a supercritical organic solvent using an organometallic tin precursor to seed growth. The coating eliminated the need for additional conductive additives and improved Si nanowire anode performance. In situ TEM experiments showed that the coated nanowires exhibit higher lithiation rates than bare Si nanowires, but the coating restricts volume expansion limiting the amount of Li storage. Nanowires with a crystalline Si core and amorphous Si shell were also synthesized. The thickness of the core and shell were controlled by altering the Si:Sn precursor ratio. Sn was found to incorporate strongly within the crystalline core, but not at all in the amorphous shell, creating nanowires with varying conductivity. The addition of tin improved Si nanowire performance in Li-
ion batteries, eliminating the need for conductive additives. Lastly, the low-temperature limit on the solution synthesis of Si nanowires via in situ seeding was explored using tin, gallium, and indium seeds.
