SnO2/graphene nanocomposite was prepared via an in situ chemical synthesis method. The nanocomposite was characterized by X-ray diffraction, filed emission scanning electron microscope and transmission electron microscope, which revealed that tiny SnO2 nanoparticles could be homogeneously distributed on the graphene matrix. The electrochemical performance of the SnO2/graphene nanocomposite as anode material was measured by galvanostatic charge/discharge cycling. The SnO2/graphene nanocomposite showed a reversible capacity of 665 mAh/g after 50 cycles and an excellent cycling performance for lithium ion battery, which was ascribed to the three-dimensional architecture of SnO2/graphene nanocomposite. These results suggest that SnO2/graphene nanocomposite would be a promising anode material for lithium ion battery. (C) 2010 Elsevier B.V. All rights reserved.
