We focus on lithium-carbon dioxide (Li-CO2) batteries, an innovative system offering the dual benefits of high-energy storage and greenhouse gas utilization. Our research involves designing advanced electrocatalytic cathodes that facilitate reversible CO2 reduction and evolution reactions, effectively lowering overpotential and improving cycle life, thereby paving the way for sustainable next-generation energy systems.

We study oxide-based solid electrolytes with high ionic conductivity and chemical stability, focusing on NASICON-type(ex. LATP, LASTP) materials for safe and durable all-solid-state batteries. 

Our research explores sulfide-based solid electrolytes with superior ionic conductivity and excellent interfacial compatibility, enabling low-resistance, high-performance all-solid-state batteries. 

We develop high-performance sodium-ion batteries based on advanced cathode materials and optimized hard-carbon anodes. Our research aims to enhance energy density, rate capability, and long-term cycling stability, establishing sodium-ion systems as cost-effective and sustainable next-generation energy storage solutions. 

We focus on lithium–sulfur batteries with exceptionally high theoretical energy density. Our research involves designing advanced sulfur cathodes that suppress polysulfide shuttling and enhance cycle stability, enabling next-generation high-energy storage systems.
