One-dimensional (1D) transition metal oxides materials with unique mesoporous structure have potential applications in the energy conversion and storage field. In this work, 1D mesoporous Fe2O3 nanowires growth on strain steel substrate were prepared through a two-step solution method and used as anode materials for lithium batteries. The electrode delivers discharge capacity of 1460 mAh·g−1 at 100 mA g−1 density after 200 cycles. Furthermore, the electrode exhibited outstanding rate capability and its reversible capacity reaches to 700 mAh·g−1 at 800 mA g−1 density. Such excellent cycle performance may ascribe to the capacitive effect caused by the unique mesoporous nanowire structure. This work may provide a facile and efficient method for the preparation of high performance Fe2O3 anode materials.
