| Abstract: | In this work, via a facile solvothermal route, we synthesized an anode material for lithium ion batteries (LIBs)-SnS2 nanoparticle/graphene (SnS2 NP/GNs) nanocomposite. The nanocomposite consists of SnS2 nanoparticles with an average diameter of 4 nm and graphene nanosheets without restacking. The SnS2 nanoparticles are firmly anchored on the graphene nanosheets. As an anode material for LIBs, the nanocomposite exhibits good Li storage performance especially high rate performance. At the high current rate of 5,10, and 20 A/g, the nanocomposite delivered high capacities of 525, 443, and 378 mAh/g, respectively. The good conductivity of the graphene nanosheets and the small particle size of SnS2 contribute to the electrochemical performance of SnS2 NP/GNs. |
