Herein, composites of tin‐assisted antimony sulfide decorated on reduced graphene oxide (Sn@Sb 2 S 3 ‐rGO) were prepared by using a simple hydrothermal method. As an anode material of sodium‐ion batteries, the Sn@Sb 2 S 3 ‐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 Sb 2 S 3 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.
