Metal　1T　phase　molybdenum　disulfide　(1T-MoS2)　is　being　actively　considered　as　a　promising　anode　due　to　its　high　conductivity,　which　can　improve　electron　transfer.　Herein,　we　elaborately　designed　stable　Sb-doped　metallic　1T　phase　molybdenum　sulfide　(1T-MoS2-Sb)　with　a　few-layered　nanosheet　structure　via　a　simple　calcination　technique.　The　N-doping　of　the　carbon　and　Sb-doping　induce　the　formation　of　T-phase　MoS2,　which　not　only　effectively　enhances　the　entire　stability　of　the　structure,　but　also　improves　its　cycling　performance　and　stability.　When　employed　as　an　anode　of　sodium-ion　batteries　(SIBs),　1T-MoS2-Sb　exhibits　a　reversible　capacity　of　493　mA　h　g−1　at　0.1　A　g−1　after　100　cycles　and　delivers　prominent　long-term　performance　(253　mA　h　g−1　at　1　A　g−1　after　2200　cycles)　along　with　decent　rate　capability.　Paired　with　a　Na3V2(PO4)3　cathode,　it　displays　a　superior　capacity　of　242　mA　h　g−1　at　0.5　A　g−1　over　100　cycles,　which　is　one　of　the　best　performances　of　a　MoS2-based　full　cell　for　SIBs.　Employed　as　the　anode　for　potassium-ion　batteries　(PIBs),　it　exhibits　a　satisfactory　specific　capacity　of　343　mA　h　g−1　at　0.1　A　g−1　after　100　cycles.　This　facile　strategy　will　provide　new　insights　for　designing　T-phase　advanced　anode　materials　for　SIBs/PIBs.　©　2022　The　Royal　Society　of　Chemistry.
