摘要：

Utilizing Fe3O4 nanorods as the active Li+ storage material and 5 wt% carbon single-walled nanotubes (SWNTs) as a "conductive net," a Li-ion anode with a high reversible capacity of 1000 mAh g(-1) (similar to 2000 mAh cm(-3)) at C rate is demonstrated. The electrodes exhibit high-rate capability and stable capacities of 800 mAh g(-1) at 5C and similar to 600 mAh g(-1) at 10C.
