Fe2O3 amorphous nanoparticles/graphene composite as high-performance anode materials for lithium-ion batteries

Amorphous Fe2O3 nanospheres anchored on reduced graphene oxide (Fe2O3/rGO) were prepared by the electron beam radiation approach. The Fe2O3/rGO exhibits a highly reversible capacity of 1064 mA h g−1 after 100 cycles at 200 mA g−1 with 88% of capacity retention and a superior rate capacity of 580 mA h g−1 at 5000 mA g−1 for Li ion storage.612
