▎ 摘　　要

Herein, composites of tin-assisted antimony sulfide decorated on reduced graphene oxide (Sn@Sb2S3-rGO) were prepared by using a simple hydrothermal method. As an anode material of sodium-ion batteries, the Sn@Sb2S3-rGO composites exhibited good electrochemical performance with an initial discharge (sodiation) specific capacity of 1002.0mAhg(-1), and they maintained a specific capacity of approximately 600mAhg(-1) at a current density of 200mAg(-1) after 60 cycles. The good performances could be explained by the composite with graphene and a bimetallic synergistic effect, both of which have an impact on the structure of Sb2S3 and subsequent electrochemical performance. This approach to the bimetallic synergistic effect for graphene composites could be a promising new idea to design other high-performance energy storage materials.
