1. Fell, Christopher Ryan. Structural Factors Affecting Lithium Transport in Lithium-Excess Layered Cathode Materials.

Degree: PhD, Materials Science and Engineering, 2012, University of Florida

Lithium ion batteries have drawn significant attention as the principle energy storage device powering today's mobile electronic equipment. Despite the increased usage, the performance of current lithium ion battery technology falls short of the requirements needed for large format applications such as electric vehicles. The layered lithium-excess oxide compounds Li[NixLi1/3-2x/3Mn2/3-x/3]O2 are of interest as a new generation of cathode materials for high energy density lithium ion batteries. Efforts to achieve a better understanding of the electrochemistry of lithium-excess materials require the connection of crystal structure to electrochemical properties. Advisors/Committee Members: Meng, Ying Shirley (committee chair), Dempere, Luisa A (committee member), Nino, Juan C (committee member), Orazem, Mark E (committee member).

2. Yang, Ming-Che. Strategies to Improve the Electrochemical Performance of Electrodes for Li-Ion Batteries.

Degree: PhD, Materials Science and Engineering, 2012, University of Florida

Lithium-ion batteries are widely used in consumer market because of their light-weight and rechargeable property. However, for the application as power sources of hybrid electric vehicles (HEVs), which need excellent cycling performance, high energy density, high power density, capacity, and low cost, new materials still need to be developed to meet the demands.

3. Li, Jianlin. Srceo3-Based Protonic Conductors for Hydrogen Production and Separation by Water Gas Shift, Steam Reforming, and Carbon Dioxide Reforming Reactions.

Degree: PhD, Materials Science and Engineering, 2009, University of Florida

Hydrogen has been considered as an ideal energy carrier for a clean and sustainable energy future. New ceramic membranes have potential to reduce the syngas (a mixture of hydrogen and carbon monoxide) cost by 30-50% and incorporate hydrogen production and separation into one unit. SrCe_(1-x-y)Zr_(y)Eu_(x)O_(3-delta) has been investigated to maximize hydrogen production and enhance stability. 10 at% europium was used to fabricate tubular micro-cracking free membranes. 20 at% zirconium was used to enhance the stability of SrCe_(0.9)Eu_(0.1)O_(3-delta). Supported SrCe_(0.7)Zr_(0.2)Eu_(0.1)O_(3-delta) thin film membranes on NiO-SrCe_(0.8)Zr_(0.2)O_(3-delta) substrates were developed. Hydrogen permeation flux through these membranes was proportional to the transmembrane Hydrogen partial pressure gradient with a 1/4 dependence and controlled by bulk diffusion. A maximum Hydrogen permeation of 0.23 and 0.21 cm3/cm2 min was obtained for the 33 mu m thick SrCe_(0.7)Zr_(0.2)Eu_(0.1)O_(3-delta) membrane at 900 °C with 100% H2 and 97% H2/3% H2O as the feed gases, respectively. Hydrogen permeation was stable under wet H2, and conditions of WGS reaction, steam reforming of methane (SRM), and carbon dioxide reforming of methane (CDRM). Thermodynamic equilibrium calculations were carried out for WGS reaction and SRM. Hydrogen production and separation through WGS reaction, SRM and CDRM with SrCe_(0.7)Zr_(0.2)Eu_(0.1)O_(3-delta) membranes were investigated. In situ removal of hydrogen through hydrogen membranes moves the reaction toward the products side resulting in higher conversion and hydrogen yield. 77% and 44% increase in the CO conversion for the WGS reaction was achieved compared to the thermodynamic calculation data under 900 °C with H2O/CO = 1/1 and 2/1, respectively. 73% and 42% enhancement in the hydrogen production was achieved simultaneously. For the SRM, the hydrogen membrane increased both the CH4 conversion and total hydrogen production by 15% at 900 oC compared to the conventional reactor with only Ni catalyst. Whereas the H2/CO in the syngas product from the SRM is too high to produce liquid fuels through the Fischer-Tropsch process, it is too low from the CDRM. However, an appropriate value can be obtained by combining the SRM and CDRM. The H2/CO between 700 °C to 900 oC, for instance, is between 1.9-1.7 and 2.5-2.0 for CH4/CO2/H2O = 2/1/1 and 2/1/1.5, respectively. ( en ) Advisors/Committee Members: Wachsman, Eric D.
