However, a huge gap between fundamental research and practical implementation remains a major obstacle to commercialization. This review first outlines critical design parameters and technical challenges in realizing practical high energy density Li-S batteries, and summarizes the recent advancements. It then systematically discusses potential strategies to address these challenges, focusing on cathode kinetics, electrolyte optimization, and anode interface engineering. The review further explores the opportunities, challenges, structural designs, and capacity enhancement strategies for next-generation all-solid-state lithium-sulfur batteries (ASSLSBs). Finally, future research directions are proposed to guide the continued development of high energy density Li-S battery technologies.
