Lithium-compatible and air-stable vacancy-rich Li₉N₂Cl₃ for high-areal capacity, long-cycling all-solid-state lithium metal batteries.

ABSTRACT: Attaining substantial areal capacity (>3 mAh/cm²) and extended cycle longevity in all-solid-state lithium metal batteries necessitates the implementation of solid-state electrolytes (SSEs) capable of withstanding elevated critical current densities and capacities. In this study, we report a high-performing vacancy-rich Li₉N₂Cl₃ SSE demonstrating excellent lithium compatibility and atmospheric stability and enabling high-areal capacity, long-lasting all-solid-state lithium metal batteries. The Li₉N₂Cl₃ facilitates efficient lithium-ion transport due to its disordered lattice structure and presence of vacancies. Notably, it resists dendrite formation at 10 mA/cm² and 10 mAh/cm² due to its intri
