摘要
A ternary composite of Fe3O4/SnO2/rGO has been synthesized via a facile one-step hydrothermal method. In the composite, rGO serves as a conductive and robust matrix, Fe3O4 and SnO2 nanoparticles are uniformly loaded on the rGO nanosheets without aggregation, due to the space-confine effect of the simultaneous nucleation and growth of Fe3O4 and SnO2 nanocrystallites. As an anode material for lithium-ion batteries, the Fe3O4/SnO2/rGO nanocomposite exhibited a reversible capacity of 947 mAh g(-1) at a current density of 200 mA g(-1) in the first cycle, and maintained 831 mAh g(-1) after 200 cycles. The cyclic performance and rate capability of the Fe3O4/SnO2/rGO are markedly improved compared with the binary counterparts of FeOx/rGO and SnOx/rGO obtained in the control experiment, as a result of enhanced structural stability and kinetics for charge and Li+ transfer due to the synergetic effect in the ternary composite.
