▎ 摘　　要

SnS2/graphene nanosheets (SnS2/GNS) composites were synthesized by a one-step hydrothermalmethod. The composites exhibit remarkably improved Li-storage ability with a good cycling life and high capability superior to that of the pure SnS2 counterpart due to a synergic effect between the graphene and SnS2 nanosheets.
