▎ 摘　　要

Fe2O3 has attracted increasing attention recently as a promising anode material for lithium-ion battery due to its high lithium storage capacity and low cost. Here, we report amorphous Fe2O3 nanoparticles anchored on reduced graphene oxide Fe2O3/rGO) by the electron beam radiation approach. The Fe2O3/rGO exhibits a highly reversible capacity of 1064 mAh g(-1) after 100 cycles at a current density of 200 mA g-1 with 88% of capacity retention and a superior rate capability of 580 mAh g(-1) at 5000 mA g(-1). The remarkable electrochemical performances are ascribed to the synergistic effects of the small particle size (similar to 2 nm), amorphous structures, large specific surface area (236 m(2) g(-1)) and conductive rGO nanosheets.
