Abstract

The inherent air instability of halide solid-state electrolytes (HSSEs) remains a critical barrier to their application in solid-state batteries. Herein, the degradation behaviour of Li₃YCl₆ under controlled atmospheric exposure was investigated in detail. Additionally, a g-C₃N₄ coating was employed to enhance the moisture resistance of Li₃YCl₆ HSSEs.
