摘      要：A facile high-energy ball-milling method was developed to synthesize SnS2-carbon(SnS2/C-x（x = 40, 50, 60 wt%）) nanocomposites. The results showed that as anode materials for lithium-ion batteries（LIBs）, the SnS2-C nanocomposites exhibited high discharge capacity and excellent cycling stability. For the optimized SnS2/C-50 wt% nanocomposite, a discharge capacity as high as 700 mA h g-1and the initial coulombic efficiency of 80.8% were achieved at a current density of 100 mA g-1. The unique structure with SnS2nanoparticles（NPs）embedded into carbon network provided abundant Li-ion storage sites, high electronic conductivity and fast ion diffusion. The ball-milled synthesis is applicable for large-scale preparation of new sulfide-based anode materials with good performance for LIBs.
