A novel SnO 2 /graphene composite has been synthesized via an in situ chemical synthesis method, in which single crystal SnO 2 nanosheets are uniformly grown on graphene support. The as-prepared products were characterized by X-ray diffraction, field emission scanning electron microscope, transmission electron microscope, Thermogravimetric analyses and Nitrogen adsorption/desorption. When used as an anode material for lithium ion batteries, the SnO 2 /graphene composite exhibits an enhanced reversible lithium storage capacity and good cyclic performance. The first discharge and charge capacities are 1,366 and 975 mAh g −1 , respectively. After 100 cycles, the reversible discharge capacity is still maintained at 451 mAh g −1 at the current densities of 100 mA g −1 , indicating that it’s a promising anode material for high performance lithium ion batteries.
