▎ 摘　　要

In this paper, we introduce an innovative method to synthesize graphene via chemical reduction of graphite oxide (GO) with the assistance of CuBr. The reduced material is examined by high-resolution transmission electron microscopy (HR-TEM), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy analysis (XPS). It is found that the graphene sheet process a thin winkled voile-like structure and fewer layers (similar to 2 layers). When used as anode material for lithium-ion batteries (LIB), the reduced GO (r-GO) based on this reducing method delivers a high reversible capacity of 1259 mA h g(-1) at a current density of 100 mA g(-1) and fine cycle performance. The increasing current density of r-GO with the growth of cycle numbers revealed the peculiar electrochemical performance. (C) 2013 Elsevier B.V. All rights reserved.
