A layered SnS 2 ‐reduced graphene oxide (SnS 2 ‐RGO) composite is prepared by a facile hydrothermal route and evaluated as an anode material for sodium‐ion batteries (NIBs). The measured electrochemical properties are a high charge specific capacity (630 mAh g −1 at 0.2 A g −1 ) coupled to a good rate performance (544 mAh g −1 at 2 A g −1 ) and long cycle‐life (500 mAh g −1 at 1 A g −1 for 400 cycles).
