MoO₂‑Doped Li₇P₃S₁₁ for High-Performance All-Solid-State Lithium Batteries.

ABSTRACT: Sulfide-based electrolytes are regarded as ideal materials for all-solid-state lithium batteries (ASSLBs) due to their amorphous structure and inherent mechanical softness. However, their practical application is hindered by limitations in ionic conductivity, lithium (Li) compatibility, and air stability. Herein, we propose a novel codoping strategy for glassy sulfide electrolytes by incorporating MoO₂ into traditional Li₇P₃S₁₁. The optimized sulfide solid electrolytes (SSEs) exhibiting an ionic conductivity of 2.57 mS/cm at room temperature attributed to the widening of Li⁺ transport pathway induced by Mo⁴⁺ doping. Furthermore, the introduction of O^2- enhances the air stability of sulfide-based solid-state electr
