Next-generation E-chem Energy Storage Systems 

All-solid-state lithium-air batteries offer a theoretical specific energy (~5220 Wh/kg) approaches to that of gasoline, through completely 4e ORR. Our work focuses on (1) understanding of 4e involved reaction mechanisms and dynamic processes of discharge product formation and decomposition at "gas-solid-solid" three-phase interfaces, (2) rational design of robust solid electrolytes for long-term stable solid-state Li-O2 batteries, and (3) field-assisted ORR/OER processes.

All-solid-state lithium–oxygen (Li–O₂) batteries offer a theoretical specific energy of ~5220 Wh/kg, approaching that of gasoline, by enabling a complete four-electron oxygen reduction reaction (4e⁻ ORR). Our research focuses on: (1) elucidating the mechanisms and dynamic processes underlying 4e⁻ ORR at gas–solid–solid three-phase interfaces; (2) rationally designing robust solid electrolytes for long-term, stable operation of solid-state Li–O₂ batteries; and (3) developing field-assisted ORR/OER strategies to reduce polarization and improve energy efficiency.

Solid-state Li-metal batteries, featuring solid electrolytes and Li-metal anodes, offer enhanced energy density and safety compared to the present Li-ion batteries. In order to advance their practical applications, our focus centers on solid electrolyte processing and addressing interfacial issues, particularly electro-chemo-mechanical degradations, to enhance long-term cycling stability.
