Metal　sulfide　has　recently　emerged　as　an　attractive　anode　material　for　sodium-ion　batteries　(SIBs)　with　large　layer　spacing　and　desirable　electrochemical　reversibility,　but　its　low-rate　performance　and　severe　volume　expansion　during　cycling　immensely　hinder　further　application.　In　this　work,　SnS@Co1-xS　nanocubes　are　uniformly　anchored　in　the　conductive　reduced　graphene　oxide　(rGO)　network　through　a　straightforward　coprecipitation　and　vulcanization　process.　The　obtained　SnS@Co1-xS-rGO　composite　with　tunable　morphologies　can　achieve　the　high　dispersion　of　nanoparticles　and　enhanced　charge　transfer　kinetics　simultaneously.　Consequently,　this　SnS@Co1-xS-rGO　electrode　possesses　an　impressive　cycling　performance　of　571.23　mAh/g　at　0.1　A/　g　after　80　cycles　and　sustains　a　high-rate　capacity　of　352.92　mAh/g　at　a　high　current　density　of　10　A/g,　which　is　far　outperforming　reported　tin/cobalt　sulfides.　It　can　be　demonstrated　that　rGO　plays　an　important　role　in　the　capacity　stability　of　bimetallic　sulfides.
