Abstract: A simple one-pot hydrothermal approach is employed for the fabrication of Fe3O4/reduced graphene oxide (rGO) nanocomposite as the superior anode material for lithium ion batteries (LIBs). The reduction of graphene oxide sheets into rGO is achieved successfully during the hydrothermal process. The well-dispersed Fe3O4 nanoparticles are decorated on the surface of rGO sheets densely and homogeneously. With the introduction of rGO, the Fe3O4/rGO nanocomposite exhibits significant improvement in the reversible capability, cycling stability and rate performance in comparison with bare Fe3O4, delivering a high capacity of 884 mAh g-1 at a current density of 200 mA g-1 after 100 cycles. This hybrid composite is a potential candidate as anode material of high performance rechargeable lithium ion batteries.
