全固态锂硫电池研究进展与展望OA

All-solid-state lithium-sulfur batteries(ASSLSBs)effectively overcome the shuttle effect of polysulfides and lithium dendrite growth issues inherent in conventional Li-S systems by establishing a solid-solid conversion pathway,thereby significantly enhancing both safety and energy density.However,their development remains challenged by sluggish reaction kinetics,poor interfacial con-tact,and substantial volume changes.This review summarized recent advances in ASSLSBs,focusing on cathode material design,solid electrolyte development,interfacial engineering,and mechanistic studies.Future research directions were also outlined,including in-depth understanding of reaction mechanisms,development of novel electrolyte systems,introduction of catalytic strategies to promote conversion reactions,and advancement of practical pouch cell configurations,aiming to facilitate the transition of ASSLSBs from fundamental research to real-world applications.
