With declaration of carbon zero in response to climate change to solve global warming, large-scale energy storage devices for electric vehicles have actively developed. Although commercialized electric vehicle adopted with a state-of-the-art lithium ion batteries (LIB) could drive over 300 miles by one single charge, there are still explosion and flammability issues of liquid based electrolyte. All-solid-state batteries (ASSBs) using solid electrolyte (SE) is one of alternative systems, and sulfide based SE could be comparable to liquid electrolyte level in terms of ionic conductivity. Among the various sulfide-based SE, Li₆PS₅Cl (LPSCl) have been considered as promising SE because of its high ionic conductivity (3x10^-3 S cm^-1) at room temperature. Here in this presentation, we will discuss about recent development of anode materials for sulfide based all-solid-state batteries. Also, we will introduce KIST research activity for silicon based anode materials.
