Fundamentals on Lithium metal battery

The rechargeable battery using metallic Li as an anode is strongly considered to be one of the most promising energy storage technology because of their high-energy density. However, the practical application have been plagued by the issue of inferior electrochemical cycling stability and safety hazard due to thermodynamically instability of Li metal anode.

Electrolyte control

In order to stabilize the interface between electrolyte and Li metal anode, we are focus on in-situ forming stable solid-electrolyte interphase (SEI) layer by regulating electrolyte components such as salt, solvent and additive.

Surface control

Our researches are focused on fabricating the stable and stiff Li metal protective layers which can suppress the growth of Li dendrite. We aimed to develop a better protective layer that can effectively maintain high efficiency over prolonged cycling in Li-metal batteries.
