▎ 摘　　要

SnS2/GCP (graphene composite powder) microcomposite was synthesized through a facile one-pot hydrothermal method. Graphene composite powder was used as an additive in the SnS2 synthesis process. In the resulting SnS2/GCP microcomposites, the sphere-like SnS2 particles were made of several intertwining SnS2 nanosheets accompanied by the formation of many pores on the surface of it and GCP was homogeneously anchored on SnS2 particles. When tested as anode material for lithium-ion batteries, the SnS2/GCP microcomposites showed a larger specific capacity (795.6 mAh.g(-1) at a current density of 0.1 A.g(-1)) and remarkable cycling stability (less than 1% capacity loss after 100 cycles) compared with pure SnS2. This superb energy storage performance could be mainly attributed to the existence of GCP that could not only prevent SnS2 particles from aggregating, but also mitigate the volume changes of SnS2 particles during charge/discharge cycle. Otherwise, the GCP could also ameliorate the electric conductivity of the SnS2 particles.
