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).
