Solid Oxide Fuel/Electrolysis Cells
Solid oxide cells (SOCs) operated as electrolyzers provide a promising and scalable method for efficiently converting electricity into renewable fuels for direct utilization, e.g., for transportation. The fuels can also be stored and converted back to electricity by reversing SOC operation to fuel cell mode, completing an electricity storage cycle with the requisite very high energy storage capacity along with relatively low cost and high efficiency. Our work focuses on improving the performance and stability of SOCs through materials design, processing, and characterization.
Lithium Batteries
Lithium-ion batteries are pervasive across consumer electronics and rapidly growing in the electric vehicle sector. Lithium ions are stored in the electrodes and shuffled back-and-forth through electrochemical reactions that we study in order to develop batteries with better performance and longer lifetimes. Our work encompasses the next generation of high-power Li-ion batteries that utilize high-voltage cathode materials and/or solid-state electrolytes.
