Fe3O4–graphene nanocomposites were prepared via a simple hydrothermal method. Ultrafine Fe3O4 nanoparticles were evenly anchored on graphene substrates. As anode material for Li-ion batteries (LIB), the nanocomposite showed high initial discharge and charge capacities of 1456 mAhg-1 and 739.9 mAhg-1 at high current density of 500 mAg-1. Additionally, the charge capacity was also retained at 698.3 mAhg-1 after 200 cycles, thereby indicating excellent cycling stability. The results suggested that the as-prepared Fe3O4–graphene nanocomposite is a promising candidate for practical application as a Li-ion battery anode material.
