All-solid-state lithium batteries: materials, processing and diagnosis

Speaker:  Prof. Yan Yao, University of Houston

Program Description:
All-solid-state lithium batteries (ASSLBs) have the potential to increase energy density, improve safety, and allow for lower manufacturing costs compared to conventional, liquid-based Li-ion batteries. However, the development of ASSLBs faces challenges and scientific gaps in materials, processing, and diagnosis. In this talk, I will first present a successful integration of a high-capacity organic cathode material into ASSLBs, which opens an alternative path toward high-energy batteries, an area currently dominated by literally two cathode materials. I will then showcase microstructure engineering of cathode composite by innovative processing. In an effort to fabricate thin solid electrolyte films less than 50 um-thick, a strong correlation between processing conditions and quality of tape-casted thin films is revealed. Finally, I will discuss how an integrated multidimensional battery diagnostic platform could benefit solid-state battery research.
