▼ It has long been recognized that secondary batteries containing lithium metal anodes have some of the highest theoretical energy densities of known battery chemistries, due to the light weight and low deposition potential of lithium metal. Lithium metal batteries have several roadblocks to effective, wide-spread implementation: lithium metal is reactive with many lithium-ion electrolytes causing low coulombic efficiency and it electrodeposits unevenly upon recharge, creating a safety hazard due to potential short-circuit. Polymer electrolytes have been under investigation for several years due to their relatively low reactivity with lithium metal and potential to electrodeposit more uniformly, due to their higher mechanical strength. This dissertation researches polymer-ceramic hybrid electrolytes with several goals: improving room temperature ionic conductivity of the electrolytes while maintaining chemical stability and mechanical integrity, allowing tunability of mechanical properties, improving lithium-ion transference number of the electrolyte, and studying the lithium metal dendrite growth as a function of electrolyte properties. It is found that constraint of the polymer chain by tethering to a nanoparticle improves ambient temperature ionic conductivity by mitigating matrix crystallization. Immobilization of anionic ligands onto the nanoparticle is found to be a facile way to synthesize nanometric lithium salts with improved transference numbers; importantly, the chemistry of the suspending solvent is found to have a significant impact on ionic conductivity. It is found that polyether-based electrolytes with and without hybrid nanoparticle fillers exhibit the same lithium metal battery lifetime regardless of mechanical properties or ionic conductivity. Surprisingly, certain copolymer electrolytes are found to provide for exceeding longer lifetimes. Advisors/Committee Members: Archer, Lynden A. (chair), Joo, Yong L.

▼ Metal-oxygen batteries recently emerge as one of the most promising post-Li-ion energy storage technologies. The key feature of this technology lies in the conversion reactions of O2 at the cathode. Such a chemistry promises the highest theoretical energy densities due to the contribution from the cathode reactions. However, the conversion between various oxygen-based species suffer severe kinetic penalties, resulting in poor energy efficiencies and low rate capabilities. To promote these reactions, catalysts with desired functionality and stability are needed. On the other hand, the O2-based chemistry incurs severe parasitic chemical reactions against various cell components, including the anode, the cathode and the electrolyte. Consequently, the reported cyclabilities of metal-oxygen batteries remain much worse than required. While stable cathode and anode candidates have been developed, further advance of this technology still hinges on developing stable electrolyte and efficient catalyst to ensure prolonged and stable cell operations. In the first part of this thesis, two distinct strategies were exploited as proof-of-concept demonstrations on the catalyst design for metal-oxygen batteries. For one, using Li-O2 batteries as a study platform, we show that the stability of catalyst can be heavily dependent on the synthesis history. A novel approach, namely carbothermal shock method, was found to enable superior chemical and structural stability of the catalyst compared to those of the catalyst prepared by conventional methods. For another, using Mg-O2 batteries as prototypical system, we demonstrate a strategy using two redox mediators that concertedly operate for discharge and recharge. As a result, a total overpotential reduction by ca. 600 mV can be achieved through manipulating the charge transfer mechanism. To meet the need of a stable electrolyte for metal-oxygen batteries, in the second part of this thesis, we analyzed the decomposition pathways of the electrolyte in the presence of reactive oxygen species. Using Li-O2 battery as a model system, we address this issue by employing a water-in-salt (WiS) electrolyte that eliminates organic solvents all together. WiS was found stable under Li-O2 battery operation conditions. When carbon was used as a cathode, much longer cycling numbers (>70) can be achieved in WiS than in organic ones. When carbon was replaced with a carbon-free cathode (TiSi2 nanonets decorated with Ru catalyst), over 300 reversible cycles was measured. The unique feature of WiS also enables other opportunities beyond O2 chemistry in metal-oxygen batteries. Toward the end of this thesis, we employ WiS for electrochemical CO2 reduction reactions. By controlling the concentration of H2O in WiS, the rate determining step on Au catalyst was found to be the first electron transfer from the electrode to CO2. Moreover, the reduced H2O activity by WiS significantly suppressed hydrogen evolution reactions, through which high selectivity toward CO can be measured. Our study provides important knowledge… Advisors/Committee Members: Udayan Mohanty (Thesis advisor).

▼ The nature of liquid-vapor interfaces is a rapidly developing field of research, aimed at ascertaining the properties and structure of this unique microscopic environment. The mechanism of aqueous electrolyte partitioning and chemistry in the aqueous-vapor interface region is explored herein, using the surface selective technique of second-harmonic generation to probe these systems via strong electronic resonances in the ultraviolet.In Chapter 1, the current descriptions of the neat water- and electrolyte solution-vapor interfaces are reviewed. Mechanistic explanations for anion adsorption to such interfaces are highlighted as an object of research. Previous applications of the surface second-harmonic technique to aqueous electrolyte systems are also described, and the results of these studies are built upon herein.In Chapter 2 the principles of applying second harmonic generation as a spectroscopic probe of liquid-vapor interfaces are discussed, followed by a consideration of the adapted Langmuir model used to interpret such studies. This model is then developed to include both cations and anions as a consequence of the requirement of electroneutrality of the solution-vapor interface. The resulting expressions are then identified as diagnostics for mechanisms of ionic adsorption to the solution interface. A discussion of the technical requirements and developments necessary to apply femtosecond ultraviolet second-harmonic spectroscopy to these systems in a reliable and reproducible manner is also presented in Chapter 2.The models developed in Chapter 2 are used to interpret the interfacial adsorption processes of aqueous sodium nitrite and sodium nitrate solutions in Chapter 3. Nitrite surface activity is found to exhibit second-order bulk concentration dependence which is then interpreted to indicate the adsorption of nitrate and sodium into the interface region as ion-pairs. These ion-pairs are found to adsorb with a standard Gibbs free energy of -37±1 kJ*mol^-1. The related sodium nitrate electrolyte is not found to be strongly surface active.The temperature dependence of the surface activity of aqueous potassium thiocyanate is explored in Chapter 4, and in terms of an adapted Langmuir adsorption model is found to be an exothermic process (-5.9±0.2 kJ*mol^-1) with a weakly unfavorable entropic component (-8±1 J*mol^-1). The process is also found to exhibit first-order dependence on bulk electrolyte concentration, indicating that the cation and anion translations are not highly correlated. These results are discussed in the framework of current theories of anionic interface adsorption mechanisms and alternative explanations are considered.The UV photochemical products of aqueous potassium and sodium thiocyanate are also observed to obscure the second-harmonic response of thiocyanate in the interface, and elemental sulfur is proposed to be excluded from the bulk solution into the interface in this system. In Chapter 5 the effect of oxidation on the interface of…

▼ Solid-state lithium ion batteries are currently at the forefront of investigations to replace conventional lithium ion batteries in order to improve overall safety and device performance. Researchers have investigated many substitutes to organic based conventional liquid electrolytes that result in high levels of Li ion conductivity. Cubic Li7La3Zr2O12 (LLZO) is a leader among solid-state electrolyte research. Unfortunately, pure LLZO at room temperature is generally a tetragonal structure that is significantly less conductive than cubic LLZO. This research uses a gallium dopant to reach the highly conductive cubic LLZO structure. However, a dopant is not enough to ensure a highly conductive LLZO sample. Lithium evaporates during the calcining and sintering stages of sample preparation. In order to reach an actual composition close to the targeted composition, additional lithium must be added, or lithium loss must be prevented. The goal of this research is to investigate the best methods and amounts of excess lithium to add in order to obtain a composition as close as possible to the targeted compositions. The most common method in literature to combat lithium loss is the addition of an excess lithium precursor to the initial set of precursors. This research studied the effect of excess Li2CO3 precursors in LLZO at zero, ten, twenty, and thirty weight percent excess. Another method studied in this research to prevent lithium loss was using a boating technique with excess lithium carbonate. Half a gram of lithium carbonate was placed on the edges of the sintering crucible, while the sample pellets were in the middle of the crucible untouched by the excess powder. The lithium carbonate powder evaporated during sintering resulting in a build-up of lithium vapor pressure in the crucible which will aid in lithium retention as it is more difficult to evaporate in high vapor pressure conditions. This research found that gallium doped LLZO (Ga0.5Li5.5La3Zr2O12) with ten weight percent excess Li2CO3 precursor along with the boating technique resulted in the highest density and highest conductivity of all samples tested. While more testing needs to be done on this research, the data shows how important lithium content is to produce a highly conductive solid electrolyte.

▼ Non-aqueous rechargeable lithium-air (O₂) batteries are receiving intense interest because of their high theoretical specific energy, which are several times greater than that of lithium-ion batteries. To achieve it, the highly reversible formation/decomposition of Li₂O₂ is required to occur in the cathode during cycling. Due to the reactivity of reduced O₂ species, the aprotic electrolyte and carbon electrode substrate would be attacked and then decomposed. The organic carbonate decomposed on discharge, forming C₃H₆(OCO₂Li)₂, Li₂CO₃, HCO₂Li, CH₃CO₂Li, CO₂ and H₂O. Part of these by-products decomposed on the subsequent charge process and the rest remained and blocked the electrode surface. Finally, the cell cycling stopped because of the depletion of electrolyte and the passivation of the electrode surface. Possible mechanisms are proposed for reactions on discharge and charge. Some other types of aprotic solvents were investigated in the same way. Ethers, amides, sulfones, dimethyl sulfoxide (DMSO), etc reveal better stability than organic carbonates. Reversible formation/decomposition was observed together with minor side-reactions. Besides electrolytes, carbon substrate of electrode also slightly decomposed. Several other substrate materials were studied. If the carbon electrodes were replaced with the nanoporous gold electrodes, less side-reaction was observed in the cells, and the cell sustained 100 cycles without severe polarisation and capacity fading. The charge performance of a Li-O₂ cell remains a challenge. Great voltage polarisation even at modest rate was observed because of the difficulty of charge transfer between solid electrode surface and solid Li₂O₂. Redox mediators were used in a Li-O₂ cell, which transported the charge between electrode surface and solid Li₂O₂, acting as an electron-hole transfer agent. The oxidation of solid Li₂O₂ was facilitated and the cell with mediator demonstrated 100 charge/discharge cycles. Advisors/Committee Members: Bruce, Peter G (advisor).

▼ Conventional lithium ion batteries use organic liquid electrolyte which is flammable and brings safety issues. Solid-state lithium ion batteries employ inorganic lithium ion conductive solid electrolytes which offer improved safety, reliability and leakage-free properties. Developing rechargeable solid-state batteries was the main goal of this research. The obstacles to the development of solid-state batteries are the lack of highly conductive solid electrolyte materials and electrode/electrolyte interface issues (e.g. large interface resistance and interface integrity problem). At the beginning of this work, thin film solid-state batteries were developed, because a thin film configuration can very effectively reduce the cell resistance from a solid electrolyte. However, the thin film batteries encountered short circuit issues caused by film defects (e.g. pin holes, particles) from the deposition process. Subsequently, bulk solid-state batteries were developed to overcome the short circuit problem. To build a bulk solid-state battery, highly conductive garnet-type Li7La3Zr2O12 (LLZO) solid electrolyte was synthesized first. A polymerized complex sol-gel method (Pechini method) was developed for synthesis, and Al-doping influence was investigated. Finally, the synthesis process was greatly simplified, and the optimal level of Al-doping was also determined. Bulk solid-state batteries with Al-LLZO solid electrolyte, Cu0.1V2O5 cathode, and Li anode were prepared and tested. The batteries exhibited high initial discharge capacities, but they encountered dramatic capacity decay problems when tested at RT. It was found that the RT capacity decay problem was caused by water vapor in air. By preventing exposure to humid air, the cell life time at RT increased. In the final chapter, a 3-dimensional (3D) solid electrolyte with a porous cathode side and a dense anode side was created. The intent was for the porous structure to greatly increase the contact area between solid electrolyte and electrode. Thus, the battery energy and powder density will increase. However, results suggest that the synthesis process need to be improved in order to get a more uniform porous structure.

The research in this thesis was performed at the Hawaii Natural Energy Institute based at the University of Hawaii at Manoa; two principal foci were addressed: (1) to design and investigate the performance of an aqueous-alkaline biocarbon fuel cell that generates power at temperatures ~500 K, (2) to determine the electrolyte chemistry at conditions similar to those of the fuel cell. Our Lab has been working in the first focus, the design of an aqueous-alkaline biocarbon fuel cell, since 2000. In 2007 T. Nunoura et al. [12] published the first paper in this topic. They studied the thermodynamics of the anode and cathode reactions and showed the experimental results of a firstgeneration, aqueous-alkaline biocarbon fuel cell built in the Lab. They showed that an aqueous-alkaline fuel cell operating at 518 K and 35.8 bar was able to realize an open-circuit voltage of 0.57 V, a short circuit current density of 43.6 mA/cm2 and a maximum power of 19 mW, using a 6M KOH/ 1 M LiOH mixed electrolyte with a catalytic silver screen/platinum foil cathode and an anode composed of 0.5 g of compacted corncob charcoal previously carbonized at 950°C. A second paper published by M. Antal and G. Nihous [13] proved that the reactions of a moderate temperature aqueous-alkaline biocarbon fuel cell may be favored at temperatures as high as 300 °C and the carbonate electrolyte may be as effective as the hydroxide electrolyte. Based on these promising findings, the work in the biocarbon fuel cell continued. Different fuel cells were designed and built to overcome the problems that arose. The fuel cell working with high concentrations of potassium carbonate solution as electrolyte showed the best performance. However, unexpected crystals determined by TG-MS as potassium bicarbonate appeared in this fuel cell that caused our research focus to take another direction: The study of the electrolyte. We decided to focus on the carbonate/bicarbonate chemistry and the understanding of the formation of these potassium bicarbonate crystals. To study the formation of the crystals, a "tubing bomb" that can stand pressures as high as 2000 psi and can be quickly heated in a sand bath was built. Previous literature [14] indicates the decomposition of dry bicarbonate into carbonate and CO2. This research focuses on the thermodynamics of this decomposition reaction in solution at conditions close to the fuel cell conditions. By determining the equilibrium constant, the thermodynamic properties (enthalpy, entropy and Gibbs free energy) of the bicarbonate decomposition reaction and the temperature at which the potassium bicarbonate in solution will completely decompose, we can determine the allowable operation temperature for the fuel cell.

▼ In traditional theories for electrolyte solutions the solvent is treated only as a dielectric continuum. A more complete theoretical picture of electrolyte solutions can be obtained by including the solvent as a true molecular species. In this thesis we report results for the structural, thermodynamic, and dielectric properties of model electrolyte solutions which explicitly include a water-like molecular solvent. The ions are modelled simply as charged hard spheres and only univalent ions are considered. The water-like solvent is also treated as a hard sphere into which the low-order multipole moments and polarizability tensor of water are included. The reference hypernetted-chain theory is used to study the model systems. The formalism of Kirkwood and Buff is employed to obtain general expressions relating the microscopic correlation functions and the thermodynamic properties of electrolyte solutions without restricting the nature of the solvent. The low concentration limiting behaviour of these expressions is examined and compared with the macroscopic results determined through Debye-Hückel theory. The influence of solvent polarizability is examined at two theoretical levels. The more detailed approach, the R-dependent mean field theory, allows us to consider the average local electric field experienced by a solvent particle as a function of its separation from an ion and is shown to have an effect upon the limiting laws of some thermodynamic properties. Model systems for liquid water are investigated over a large range of temperatures and pressures and are found to have dielectric constants which agree reasonably well with experiment. Model aqueous electrolyte solutions are studied both at infinite dilution and at finite concentration, but only at 25°C. The equilibrium dielectric constants of these solutions are qualitatively consistent with those of experiment. A remarkable diversity of behaviour is obtained for our model solutions by simply varying the hard-sphere diameters of the ions. In many cases the behaviour observed for thermodynamic quantities is in accord with experiment. The ion-ion, ion-solvent and solvent-solvent correlation functions of the solutions are examined in detail, revealing a wealth of structural information. Ionic solvation is generally found to be very sensitive to the details of the interactions within the system.

▼ Lithium-ion batteries are important in many aspects of modern life from portable electronics to electric vehicles. Their high specific energy, light weight, and design flexibility make them especially useful compared to other types of battery technologies. However, there remains room for improvement with regards to battery stability, safety, and increased capacity. One strategy for making lithium batteries both safer and more practical is by using solid polymer electrolytes (SPEs). Not only does the replacement of small molecule liquid electrolytes by SPEs significantly reduce the flammability of the battery, SPEs also make possible the construction of lighter weight batteries with increased flexibility in form factor. However, SPEs have not been widely incorporated into commercial batteries at the current time. Their applications are limited primarily due to their relatively low conductivities (~10-5 S/cm) at ambient temperatures. The first project describes the synthesis and characterization of a set of polyester-based polymer electrolytes. The polyesters were synthesized using transition metal-catalyzed alternating copolymerization of epoxides and anhydrides, which allowed the incorporation of a variety of Li+ ion coordinating functional groups including allyl ethers, pendant oligo(ethylene glycol), and esters. The bulk properties of the polymers and polymer-salt mixtures were investigated and compared to results from molecular dynamics (MD) simulations. The simulations were also used to probe the mechanism of Li + binding and transport in the polyesters. The simulations suggested that the relatively low Li + conductivity of the polyesters compared to PEO was most likely due to a lower than optimal density and spacing of the Li + binding sites in the polyesters. The insights from the polyester study were used to design a set of polyethers to further elucidate the source of PEO's unusually high ionic conductivity, as well as potentially improve the conductivity by further optimizing binding site connectivity. The polyethers were synthesized using acyclic diene metathesis (ADMET) polymerization, and a set of polymers was made with very specific and systematic alterations in structure. By studying the ionic conductivity as a function of temperature, we were able to analyze the effect of binding group density and pattern on the ionic conductivity and Li + ion transport mechanism in polyethers. The third project was inspired by the search for catalysts to develop novel high performance materials. Enantioselective [beta]-diiminate zinc catalysts were designed for the synthesis of highly isotactic polycarbonates from CO2 and meso epoxides. The ligand optimization process is described, as well as the characterization of the catalyst and isotactic poly(cyclohexene carbonate).

▼ Exponential increase in demand and continuous improvements in standard of batteries has attracted the need for exploring every possible ways of improving its performance. Enhancing cathode/anode capacity, stability and upgrading the current class of gel and liquid electrolytes, efficient packing of the cell stacks while simultaneously helping it withstand rough conditions like temperature, pressure and mechanical shocks are being constantly explored. Due to the high oxidation potential of the metal oxide cathodes, lithium batteries may suffer from decomposition reactions of the liquid organic solutions used as electrolyte. The performance, flexibility and safety aspects of lithium batteries have been greatly improved since the inception of solid polymer electrolytes (SPE). The replacement of liquid electrolyte with a thin polymer membrane is proven to be a highly desirable solution. Polymer electrolyte membranes (PEMs) or interchangeably solid polymer electrolytes (SPE) had shown to be good potential components of the energy storage (i.e., Li batteries) and energy conversion devices (i.e., polyelectrolyte membrane fuel cells PEMFCs). In these devices, the PEM acts as a separator and a charged ion carrier (Li+ ions in Li batteries, H+ ion in PEMFCs). The mobility of ions μ in the PEMs determines the conductivity σ of the PEMs and the performance of the energy storage and energy conversion devices; hence the two parameters play an important role. In this thesis study sulfonated poly ether ether ketone was used as a polymer medium for the conduction of lithium. Two batches of sPEEK were synthesized, each with different degrees of sulfonation. The values of degree of sulfonation were ascertained to be 0.75 for batch 1 and 0.85 for batch 2 polymers using Nuclear magnetic resonance (NMR) spectroscopy. A comparative study of the two polymers (initially without any lithium salt) in terms of lithium conductivity and stability were assessed using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). Then Lithium Boron Phosphate - LiBPO4, an inexpensive filler which can act as a structural and functional material in the conduction of lithium with the membrane was synthesized, its different phases studied using XRD and cast along with the sPEEK polymers. The effect of loading of LiBPO4 in the sPEEK polymer itself was studied by making different polymers of 10%, 15%, 20% by weight and the results of lithium conduction and stability were examined in dry membranes as well as membranes swollen in organic, aprotic solvents. The effect of drying of membranes post lithiation was given particular attention and a new setup to dry the same is suggested. Moreover two different ways of lithiation were attempted – the first one was soaking in 2M solution of lithium hydroxide monohydrate solution, the second was completely immersing it in LiPF6 liquid electrolyte with a small piece of Li metal. The top three best conducting membranes were used to carry out the electroplating experiment to confirm if the lithium had… Advisors/Committee Members: Kelder, Erik (mentor), Delft University of Technology (degree granting institution).

Ces travaux ont pour objet la synthèse et la caractérisation de nouveaux électrolytes polymères pour batterie lithium métal polymère (LMP). L’objectif principal de ces électrolytes est de combiner une conductivité ionique élevée jusqu’à basse température et une résistance efficace contre les dendrites de lithium. Pour y parvenir, trois catégories de copolymères à bloc ont été élaborés, ils permettent d’obtenir une synergie de propriétés à priori antagonistes au sein d’un même matériau. Premièrement, la rigidité du polystyrène (PS) a été combinée à la conductivité du polyoxyéthylène (POE) dopé avec un sel de lithium (LiTFSI). Le POE a été préalablement modifié pour en abaisser la température de fusion (Tf) initialement située à 60°C, ce qui permet d’atteindre de hautes conductivités (7.10-5 S.cm-1) à 40°C, associées à un module d’Young de 0,3 MPa. Cependant, les bonnes conductivités de ces matériaux ne sont assurées que par une petite fraction de Li+ (t+=0,15). Cela crée des gradients de concentration qui limitent les performances des batteries. Pour pallier cela, l’anion TFSI a été greffé sur le bloc PS (PSTFSI), augmentant le t+ à 1. Le bloc PSTFSI combiné à du POE modifié a permis des conductivités remarquables pour un électrolytes solide (10-6 S.cm-1 @ 40°C). Dans un second temps, l’ajout d’une chaine perfluorée entre le PS et l’anion a permis un gain supplémentaire de conductivité par rapport au PSTFSI (2.10-5 S.cm-1 @ 60°C), uniquement assurée par les Li+. Dans chacune des trois catégories d’électrolytes plusieurs compositions ont été synthétisées, nous permettant de suivre l’impact de cette composition sur les morphologies, les propriétés thermodynamique et mécanique ainsi que sur les propriétés de transport. Finalement, des batteries LMP de laboratoire ont été assemblées avec les meilleurs électrolytes.

This work deals with synthesis and characterization of new polymer electrolytes for lithium metal polymer (LMP) batteries. The main challenge of polymer electrolytes is to combine both high ionic conductivity at low temperature and good mechanical properties. To overcome these issues, block copolymers have been designed. Remarkable properties are reached thanks to the self-assembly of these triblock copolymers. Mechanical properties are given by stiff polystyrene (PS) domains whereas ionic mobility operates in an ionophilic phase, polyoxyethylene (POE) with a lithium salt (LiTFSI). By introducing chemical defects in the POE backbone, melting temperature of the copolymer has been considerably lowered leading to conductivities of about 7.10-5 S.cm-1 and a Young’s modulus of 0.3 MPa at 40°C. If interesting properties are obtained thanks to this strategy, the small fraction of conductivity insured by lithium ions (t+=0.15) remains an issue. The low t+ leads to large concentration gradients limiting the performances of the system. In a second approach, TFSI anions have been covalently tethered on the PS backbone, raising the t+ to 1. An important increase of Li+ conductivity was obtained by adding a…

Ces travaux de thèse résultent d’une étude multidisciplinaire dont l’objectif final était d’élaborer une électrode négative à base de zinc pour accumulateur alcalin rechargeable. L’origine de l’étude tient en la découverte surprenante, par la société EASYL, d’un nouveau procédé de synthèse du zincate de calcium (CAZN), matière électrochimiquement active et connue pour ses bonnes caractéristiques de cyclabilité en générateur alcalin rechargeable. L’intérêt de cette découverte réside dans ses caractéristiques avantageuses : la synthèse ultra-rapide se fait en continu, n’utilise aucun système de chauffe ni de solution alcaline et conduit à une granulométrie et une pureté contrôlée du zincate de calcium ; la rendant compatible avec une production industrielle de ce matériau.L’utilisation de CAZN en batterie prismatique de 4 Ah a permis la découverte d’un fonctionnement des électrodes de type cœur-coquille, leur cœur actif étant riche en zinc et leur surface jouant le rôle de couche protectrice ; si la capacité nominale est choisie inférieure à la capacité théorique de la batterie, l’activité à cœur de l’électrode est maintenue sans que sa surface ne soit altérée, ce qui permet d’éviter (ou de ralentir) la formation de dendrite, un effet très bénéfique sur la cyclabilité de l’électrode.Cependant, l’utilisation du zincate de calcium comme seule source de matière active ne semble pas appropriée. En effet, la formation du cœur de zinc conduit à l’apparition d’une couche résistive d’hydroxyde de calcium à sa périphérie, diminuant les performances électrochimiques des électrodes. Aussi surprenant que cela puisse paraitre, il est cependant possible de régénérer une électrode vieillie ayant formé une couche riche en hydroxyde de calcium par un simple repos, soit un arrêt pur et simple de la batterie. La formation de cette couche résistive peut en outre être évitée par l’ajout d’oxyde de zinc sacrificiel au zincate de calcium, additif actif qui s’est avérée efficace tant d’un point de vue morphologique qu’électrochimique.En revanche, la formation contrôlée d’un cœur riche en zinc conduit à la densification du zinc sur lui-même, et diminue la surface de contact matière active/électrolyte et donc les performances électrochimiques. Partant de ce constat, la structure de l’électrode a été intégralement repensée pour permettre la formation, non pas d’un cœur de zinc, mais de plusieurs d’entre eux, par l’emploi de collecteurs de courant multicouches ; cette méthodologie, aussi simple qu’efficace, conduit à d’excellentes performances pratiques et une cyclabilité optimale de la batterie.

The work presented in this document results from a multidisciplinary study, the unique goal of which is to develop a negative electrode for alkaline rechargeable batteries. At the origin of this thesis, is the surprising discovery by EASYL of a new way to synthesize calcium zincate (CAZN), an electrochemically active material known for its good cycling characteristics in alkaline batteries. The advantage of such a discovery resides in its unique…
