Micron-sized　Si-based　materials　have　attracted　extensive　attention　for　lithium-ion　batteries　due　to　their　high　theoretical　capacity　and　low　cost.　However,　its　large　volume　expansion　and　low　conductivity　limit　its　further　development.　Here,　a　Si/ZnS　anode　material　is　prepared,　in　which　ZnS　nanoparticles　are　uniformly　attached　to　the　surface　of　micro-Si　particles.　The　conversion　reaction　of　ZnS　generates　metal　Zn　and　Li2S,　and　the　alloying　reaction　of　Zn　generates　LixZn,　the　metal　Zn　and　LixZn　are　used　as　conductive　additives　to　improve　the　conductivity　of　the　composites,　while　Li2S　is　used　as　an　artificial　solid　electrolyte　interfacial　phase　to　promote　the　stability　of　the　solid　electrolyte　interface　of　the　composites,　so　that　the　prepared　micron-sized　Si-based　anode　exhibits　excellent　cycling　stability.　At　a　current　density　of　0.5　A　g-1,　the　initial　coulombic　efficiency　reaches　78.67　%　and　the　discharge　specific　capacity　is　1540.2　mAh　g-1　after　200　cycles.
