Title: Batteries: The missing piece for sustainable transport and aviation
Date: Tuesday, December 18, 2018
Time: 4:00 PM
Venue: SSCU Auditorium

Batteries are a key piece towards developing sustainable routes for transportation and aviation. In this talk, I will outline the performance requirements of batteries needed for electrifying transportation and aviation. Lithium metal anodes present one approach to address the requirements for transportation and I will discuss our work on enabling lithium metal anodes and optimizing solid state electrolytes to achieve stable electrodeposition. Specifically, I will discuss the potential for solid inorganic electrolytes to suppress the formation of dendrites. In order to enable electric aviation, stable organic liquid electrolytes are necessary and I will discuss our data-driven approach for the search for stable liquid electrolytes that can withstand the harsh operating conditions of next-generation batteries. Finally, I will show our semi-autonomous robotic experimentation setup for optimization of liquid electrolytes.
