Abstract

A hybrid anode based on SnS nanosheets bonded with reduced graphene oxide (SnS NS/RGO) and synthesized with graphene oxide is formed through a facile solvothermal method. It is found that the 2D SnS nanosheets with few layers are well dispersed on the crumpled reduced graphene oxide surface. Electrochemical tests indicate that the SnS NS/RGO hybrid exhibits a very high reversible capacity (791 mA h gāˆ’1) with excellent cycle stability and significantly enhanced rate capability. The factors contributing to the enhanced electrochemical performance of the hybrid anode can be ascribed to the chemically bonded interface between SnS NS and RGO, creating effective charge transportation with electron coupling in the novel two-dimensional composite nanostructure. This work provides insights into the structural design of SnS-based hybrid electrode materials, which will be important for the future development of high performance electrode materials.
