Abstract
In this manuscript, we introduce a facile hydrothermal method for the controlled growth of SnO 2 nanoparticles onto graphene oxide. Hydrazine plays a fundamental role in controlling the formation and crystallization of SnO 2 nanoparticles, and the reduction of graphene oxide to graphene. The SnO 2-graphene composite consists of 3-4 nm monodisperse SnO 2 nanocrystals homogeneously dispersed at the surface of graphene. It is demonstrated that the composite can accommodate the large volume change of SnO 2 which occurs during lithiation-delithiation cycles. When used as an anode material for lithium ion batteries, it exhibits a first discharge capacity of 1662 mA h g -1, which rapidly stabilizes and still remains at 626 mA h g -1 even after 50 cycles, when cycled at a current density of 100 mA g -1. Even at the very high current density of 3200 mA g -1, the composite displays a stable capacity of 383 mA h g -1 after 50 cycles.
