Abstract Sulfide solid electrolytes (SSEs) have become an ideal candidate material for all‐solid‐state Li metal batteries (ASSLMBs) because of their high ionic conductivity. However, the vile incompatibility and poor air stability SSEs barriers commercial application. Herein, novel 6+2x P 1−x In x S 5−1.5x O 1.5x Cl (0 ≤ 0.1) are synthesized via co‐doped 6 PS 5 Cl.
