Abstract：All-solid-state lithium-sulfur batteries(ASSLSBs)based on sulfide electrolyte systems have emerged as highly promising next-generation energy storage technologies,owing to their ultra-high theoretical energy density,intrinsic safety,and low-cost potential.This article provides a systematic review of their research progress,core challenges,and commercialization strategies.In terms of material systems,sulfide-based solid electrolytes have become a focal point of research due to their high ionic conductivity,excellent mechanical properties,and processing advantages.Composite design is employed to balance conductivity with energy density,while the anode side must address issues such as the high reactivity of lithium metal/alloys and dendrite growth.Industrialization still faces multiple challenges:it is necessary to reduce electrolyte thickness and construct stable interfaces to enhance energy density and suppress side reactions,develop scalable manufacturing processes,and promote standardization of materials and processes.Moving forward,strengthening interdisciplinary collaboration is essential to accelerate the practical application of ASSLSBs..
