ABSTRACT=<p>SnS<sub>2</sub> nanosheets/reduced graphene oxide (rGO) composite was prepared by reflux condensation and hydrothermal methods. In this composite, SnS<sub>2</sub> nanosheets <italic>in-situ</italic> grew on the surface of rGO nanosheets. The SnS<sub>2</sub>/rGO composite as anode material was investigated both in lithium ion battery (LIB) and sodium ion battery (SIB) systems. The capacity of SnS<sub>2</sub>/rGO electrode in LIB achieved 514 mAh g<sup>−1</sup> at 1.2 A g<sup>−1</sup> after 300 cycles. Moreover, the SnS<sub>2</sub>/rGO electrode in SIB delivered a discharge capacity of 645 mAh g<sup>−1</sup> at 0.05 A g<sup>−1</sup>; after 100 cycles at 0.25 A g<sup>−1</sup>, the capacity retention still keep 81.2% relative to the capacity of the 6th cycle. Due to the introduction of rGO in the composite, the charge-transfer resistance became much smaller. Compared with SnS<sub>2</sub>/C electrode, SnS<sub>2</sub>/rGO electrode had higher discharge capacity and much better cycling performance.</p>
