Hollow-sphere Fe2O3 is synthesized as a lithium-ion battery anode. Current densities for the initial material activation are important, related to electrode stability during cycling. The as-prepared anodes are able to retain 92% capacity after 1000 cycles at 1 A g-1. The full-cells assembled with Fe2O3 anodes and LiFePO4 cathodes exhibit good electrochemical properties.
