Nanostructured LiFePO4 is appealing cathode material for rechargeable lithium batteries. Herein, however, we report the intriguing anode properties of carbon coated LiFePO4 nanocrystals. In the potential range of 0–3.0 V, the LiFePO4 nanocrystal electrodes afford high reversible capacity of 373 mAh[Formula: see text]g[Formula: see text] at a current rate of 0.05 A[Formula: see text]g[Formula: see text] and retains 239 mAh[Formula: see text]g[Formula: see text] at a much higher rate of 1.25 A[Formula: see text]g[Formula: see text]. In addition, it is capable of sustaining 1000 cycles at 1.25 A[Formula: see text]g[Formula: see text] without any capacity fading. Such superior properties indicate that nanostructured LiFePO4 could also be promising anode for rechargeable battery applications.
