Abstract

Fe 3 O 4–graphene nanocomposites were prepared via a simple hydrothermal method. Ultrafine Fe 3 O 4 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 1456mAhg-1 and 739.9mAhg-1 at high current density of 500mAg-1. Additionally, the charge capacity was also retained at 698.3mAhg-1 after 200 cycles, thereby indicating excellent cycling stability. The results suggested that the as-prepared Fe 3 O 4–graphene nanocomposite is a promising candidate for practical application as a Li -ion battery anode material.
