Using　a　simple　hydrothermal　method,　we　developed　a　Si@SnS　anode　material　with　SnS　nanoparticles　uniformly　attached　to　the　surface　of　silicon　nanoparticles.　Utilizing　the　first　charge-discharge　reaction　mechanism　of　SnS,　combined　with　the　artificial　solid　electrolyte　interphase　to　improve　the　solid　electrolyte　interphase　stability　of　silicon-based　materials　and　the　introduction　of　conductive　additives　to　improve　the　conductive　properties　of　silicon-based　materials,　the　Si@SnS　material　exhibits　very　excellent　performance　when　applied　to　lithium-ion　battery　anodes.　At　a　current　density　of　0.5A.g−1,after　two　cycles,　the　overall　resistance　of　the　Si@SnS　material　battery　is　reduced　by　nearly　55%　relative　to　the　resistance　of　the　pure　silicon　battery.　As　a　half-cell　anode　material,　the　first　coulombic　efficiency　of　Si@SnS　at　a　current　density　of　1A.g−1　reached　85%,　and　after　200　cycles,　it　provided　a　reversible　capacity　of　1790　mAh.g−1　and　a　capacity　retention　rate　of　74.6%.　©　2021
