A layered SnS2-reduced graphene oxide (SnS2-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).
