Abstract
- A ternary composite of Fe 3 O 4 /SnO 2 /rGO has been synthesized via a facile one-step hydrothermal method. In the composite, rGO serves as a conductive and robust matrix, Fe 3 O 4 and SnO 2 nanoparticles are uniformly loaded on the rGO nanosheets without aggregation, due to the space-confine effect of the simultaneous nucleation and growth of Fe 3 O 4 and SnO 2 nanocrystallites. As an anode material for lithium-ion batteries, the Fe 3 O 4 /SnO 2 /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 Fe 3 O 4 /SnO 2 /rGO are markedly improved compared with the binary counterparts of FeO x /rGO and SnO x /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.
