Abstract

Herein, we demonstrate a facile method to prepare hollow-structured oxygen-vacancy-rich Fe₂O₃/MnO₂ nanorods. Our results show that oxygen vacancies are induced by nanoscale ion intermixing between Fe and Mn ions during the annealing process. Owing to their unique core-shell hollow nanostructure and the presence of oxygen vacancies, the Fe₂O₃/MnO₂ nanorods show excellent electrochemical performances as an anode material for lithium ion batteries and a reversible capacity higher than 700 mA h g^-1 after 2000 cycles.
