All-solid-state batteries (ASSBs) have garnered significant interest as a potential energy storage solution, primarily because of their enhanced safety features and high energy density. Sulfide solid electrolytes have emerged as a focal point in solid-state battery research, attributed to their exceptional ionic conductivity, wide electrochemical stability range, and robust mechanical properties. However, their practical performance is frequently limited by interfacial compatibility issues with lithium-metal anodes and challenges associated with the high-cost of sulfide solid electrolyte. Therefore, the design and optimization of low-cost sulfide solid electrolytes, as well as compatibility strategies for lithium metal anodes, are vital for broadening the application prospects of sulfide solid electrolytes. This review systematically analyses the classification and synthesis methods of sulfide solid electrolytes, focusing on low-cost synthesis approaches. Furthermore, this review examines recent advancements in optimizing the interface between sulfide solid electrolytes and lithium-metal anodes, and provides strategic insights into the optimal selection and engineering of materials for the interfacial layer of lithium-metal anodes by synthesizing the latest experimental and theoretical findings. Finally, this review provides insights into the developmental trends and future prospects of sulfide all-solid-state lithium-metal batteries (ASSLMBs), offering valuable guidance for the practical application of high-performance ASSLMBs.
