All-solid-state　batteries　(SSBs)　are　prospective　candidates　for　a　range　of　energy　accumulation　systems,　delivering　higher　energy　densities　compared　to　batteries　which　use　liquid　electrolytes.　Amongst　the　numerous　solid-state　electrolytes　(SEs),　sulfide-based　electrolytes　in　particular　have　received　more　attention　given　that　they　have　a　high　ionic　conductivity.　However,　the　incompatibility　between　the　electrode　and　SEs　is　still　an　ongoing　challenge　that　leads　to　poor　electrochemical　performance.　In　this　work,　we　focus　on　1T-MoS2.　It　is　well　known　that　1T　metallic　MoS2　is　unstable　even　at　room　temperature.　However,　we　showed　that　1T-MoS2　can　be　stabilized　at　600　°C　for　at　least　2　h,　and　the　1T-MoS2-600　interlayer　spacing　expanded　to　0.95　nm.　The　high　crystallinity　of　the　1T　phase　is　highly　compatible　with　solid　electrolytes　and　coupled　with　the　increased　interlayer　spacing,　so　in　the　all-solid-state　lithium-ion　battery　(ALLLIB),　we　achieved　outstanding　cycling　performance.　At　the　current　density　of　0.2　C　(1　C　=　670　mA　g−1),　this　material　delivered　a　capacity　of　406　mA　h　g−1　after　50　cycles.　©　2022　by　the　authors.
