dc.description.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. | - |
