Summary: A stable interface and preventing dendrite-growth are crucial for the long-life of solid-state Li batteries using sulfide-based solid electrolytes (SEs) and Li metal anodes. This study reports a strategy using Si doping in Cl-rich argyrodites that enables self-engineered metastable decomposition, leading to the realization of these two factors simultaneously. The metastable Cl atoms react with Li atoms, depleting locally deposited/grown Li crystal nuclei and generating electrically insulated LiCl shells at the grain boundaries. These shells prevent Li redeposition and act as self-protective layers, enabling an ultra-long life ASSLB with Li metal anodes under high current densities at room temperature.

Summary: Sulfide solid electrolytes (SSEs) with ultrahigh ionic conductivity and good machinability are gaining attention for all-solid-state Li metal batteries (ASSLMBs). However, current SSEs face challenges of poor Li metal compatibility and air-stability. In this study, argyrodite-based SSEs were synthesized via co-doping of Bi and O in Li6PS5Cl, resulting in an electrolyte with ultrahigh ionic conductivity and excellent structural stability. The electrolyte also triggers the formation of Li-Bi alloy, improving interfacial compatibility and cyclic stability.
