All-solid-state lithium batteries have emerged as a critical solution for next-generation energy storage technologies, thanks to their outstanding energy density and intrinsic safety. Among all types of solid electrolyte systems, Li-argyrodite sulfide solid electrolytes feature excellent room-temperature ionic conductivity and remarkable mechanical deformability, demonstrating prominent commercialization potential. Nevertheless, such electrolytes are constrained by high humidity sensitivity, unsatisfactory interfacial stability and relatively high manufacturing costs, greatly hindering their large-scale industrial application. The industry is in urgent need of a systematic review of core challenges and corresponding solutions along the path from fundamental research to large-scale application.
Targeting these industry pain points, the research team adopted a full-chain perspective spanning fundamental research and industrial application. They systematically sorted out and analyzed the ion transport mechanisms, regulation strategies and air stability improvement schemes of Li-argyrodite sulfide solid electrolytes, explored effective technical approaches to enhance the air stability of such materials, and thoroughly examined the core interfacial challenges and optimization strategies for all-solid-state lithium batteries. Meanwhile, the paper put forward feasible technical solutions for the large-scale application of sulfide solid electrolytes from multi-scale and multi-level dimensions covering materials, electrodes and devices. This study provides solid theoretical support and engineering referencesfor the laboratory-to-industry technology translation of sulfide solid electrolytes and the industrial promotion of all-solid-state lithium batteries.
