A novel and facile approach is applied to couple SnS2 nanoparticles with three-dimensional reduced graphene oxide (3DRGO), resulting in a SnS2@3DRGO composite which displays remarkable cycling performance and high reversible capacity as anode material for sodium ion batteries. The SnS2@3DRGO composite is equipped with SnS2 nanoparticles with the size of 30 nm robustly anchoring on 3DRGO. Compared with SnS2, SnS2@3DRGO delivers a higher specific capacity of 753.8 mAh g(-1) at 0.1 A g(-1) and a superior long cycle-life with a capacity retention rate of 75.4% after 700 cycles at 2 A g(-1). During the cycling process, the unique porous structure and well confined SnS2 nanoparticles by graphene buffer layer make a critical difference in achieving rapid kinetic of insertion/extraction and suppressing aggregation of SnS2 and the corresponding discharge product, rendering SnS2@3DRGO to be an extraordinary and stable anode material for SIBs.
