ABSTRACT
A sheet-on-sheet reduced graphene oxide-ß-In(2)S(3) (RGO-In(2)S(3)) composite, was successfully synthesized via a one-step mild 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 ß-In(2)S(3) sheets and the effective combination of ß-In(2)S(3) and RGO sheets. This results in a high specific surface area and good conductivity of RGO-In(2)S(3) 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.
