SnO2/Graphene Nanocomposite as an Enhanced Anode Material for Lithium Ion Batteries

We report the fabrication of a tin nanoparticles coated anode in graphene (SnO2 /graphene) for lithium-ion batteries. As an anode material for Li ion batteries, it has 806mAhg-1 and 683mAhg-1 capacities for the first discharge and charge, respectively, which is more than the theoretical capacity of tin oxide, and has good capacity retention with a capacity of 606mAhg-1 after 30 cycles.
