All-Solid-State Batteries (ASSBs)

Our group focuses on enabling novel electrolyte and electrode materials for high-performance all-solid-state batteries. Research efforts include the fundamental studying of the electrode-electrolyte interface and an understanding of the mechanical effect on the cell level by utilizing advanced characterization techniques. The fabrication process of the electrodes and the cells including the dry process and pressurization method is also studied as well as the next-generation sodium ASSB system for the cost-effective alternatives.

Advanced Lithium-ion Batteries (LIBs)

To maximize energy density and performance, high-capacity anode materials including transition metal oxides and lithium metal,

in addition to novel organic liquid electrolytes, are being researched. With electrochemical and analytical backgrounds, our group investigates the degradation mechanism of commercial LIB cells with the collaboration of industry partners. In addition, an alternative system including aqueous electrolytes and sodium-based materials is also developed.
