A simple, green, and ultra-fast one-pot supercritical ethanol (scEtOH) route was developed to synthesize tin sulfide-reduced graphene oxides (SnS-RGOs) by the simultaneous reduction of GO and the heterogeneous nucleation and growth of SnS nanosheets on the basal plane of RGO. The SnS-RGO composites exhibited a mesoporous structure with porosity up to 63%. When tested as an anode in lithium-ion batteries, the SnS-RGO composite with 44 wt% SnS loading delivered high reversible capacity of 613 mAh g(-1) at 50 mA g(-1) after 100 cycles and high rate capacity of 198 mAh g(-1) at a high charge-discharge rate of 1 A g(-1).
