Abstract

Abstract: Herein, composites of tin‐assisted antimony sulfide decorated on reduced graphene oxide (Sn@Sb2 S3 ‐rGO) were prepared by using a simple hydrothermal method. As an anode material of sodium‐ion batteries, the Sn@Sb2 S3 ‐rGO composites exhibited good electrochemical performance with an initial discharge (sodiation) specific capacity of 1002.0 mAh g −1, and they maintained a specific capacity of approximately 600 mAh g −1 at a current density of 200 mA g −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 Sb2 S3 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.
