Li–Solid Electrolyte Interfaces/Interphases in All-Solid-State Li Batteries

Abstract The emergence of all-solid-state Li batteries (ASSLBs) represents a promising avenue to address critical concerns like safety and energy density limitations inherent in current Li-ion batteries. Solid electrolytes (SEs) show significant potential in curtailing Li dendrite intrusion, acting as natural barriers against short circuits. However, the substantial challenges at the SEs−electrode interface, particularly concerning the anode, pose significant impediments to the practical implementation of ASSLBs. This review aims to delineate the most viable strategies for overcoming anode interfacial hurdles across four distinct categories of SEs: sulfide SEs, oxide SEs, polymer SEs, and halide SEs.…
