摘要：
A sheet-on-sheet reduced graphene oxide-beta-In2S3 (RGO-In2S3) composite, was successfully synthesized via a one-stepmild method. This fresh composite used as an anode material exhibits enhanced cyclability and specific capacity for lithium storage. These results are linked with the intrinsic layered structure of beta-In2S3 sheets and the effective combination of beta-In2S3 and RGO sheets. This results in a high specific surface area and good conductivity of RGO-In2S3 composites, with higher transport rates of electrolyte ions and electrons, and a more effective electrochemical reaction of the active material. This facile and rapid synthesis method is a promising route for a large-scale production of graphene-based metal sulfides, which could be used as electrode materials for Li-ion batteries.
