We demonstrate a facile, single step, low temperature and energy efficient strategy for the synthesis of SnO 2 -reduced graphene oxide (RGO) nanocomposite where the crystallization of SnO 2 nanoparticles and the reduction of graphene oxide takes place simultaneously by an in situ chemical reduction process. The electrochemical property of the SnO 2 -RGO composite prepared by using low concentrations of reducing agent shows better Li storage performance, good rate capability (378 mAh g −1 at 3200 mA g −1 ) and stable capacitance (522 mAh g −1 after 50 cycles). Increasing the reductant concentration lead to crystallization of high concentration of SnO 2 nanoparticle aggregation and degrade the Li ion storage property.
