Inorganic　solid　electrolyte-based　all-solid-state　lithium-sulfur　batteries　(ASSLSBs)　have　garnered　significant　attention　due　to　their　inherent　safety　and　higher　energy　density,　making　them　a　promising　candidate　for　the　upcoming　lithium　batteries.　However,　employing　sulfur　as　the　active　material　in　all-solid-state　composite　cathodes　introduces　two　critical　challenges:　sluggish　electrochemical　reaction　kinetics　and　insufficient　solid-solid　contact　between　the　sulfur,　conductive　additive,　and　solid　electrolyte　phases.　These　issues　directly　impact　battery　performance　and　hinder　the　commercialization　of　ASSLSBs.　In　this　comprehensive　review,　the　underlying　causes　of　these　issues　are　first　discussed　to　gain　a　fundamental　understanding　of　potential　improvement　directions.　Subsequently,　we　summarize　the　recent　progress　in　enhancing　sulfur　reaction　kinetics　and　optimizing　solid-solid　contact.　The　fundamental　principles,　fabrication　techniques,　and　resultant　performance　enhancement　of　diverse　strategies　are　systematically　categorized,　summarized,　and　evaluated.　Finally,　the　challenges　and　future　outlook　of　advanced　ASSLSB　cathode　research　are　discussed　at　the　end　of　this　review.　(Figure　presented.)　©　Science　China　Press　2025.
