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.
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.
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.
