Abstract A facile one-step hydrothermal method has been developed to synthesise Fe2O3-graphene nanocomposites using l-arginine as the hydrolysis-controlling agent. In the synthesised composites, highly crystallized Fe2O3 nanocrystals with an average size of ∼50 nm are firmly anchored on the graphene sheets. When applied as the anode material for lithium ion batteries, the resulting Fe2O3-graphene nanocomposites show excellent cycling stability and good rate performance. The composites deliver a capacity of 946 and 634 mA h g-1 at a current density of 200 and 2000 mA g-1, respectively. After cycling at 200 mA g-1 for 450 cycles, a capacity of 1049 mA h g-1 can still be maintained.
