Fund Project: We are grateful for the financial support from the Natural Science Foundation of Hunan Province (Grant No. 04JJ0388) and from Central South University.

LiFePO₄/C was synthesized by high temperature solid-state method with cheap Fe₂O₃, LiH₂PO₄ and glucose as raw materials in absence of inert gas. The sample had ordered olivine-type structure other impurities characterized by the test of X-ray diffraction(XRD). The charge-discharge test showed the sample could demonstrate 120.5 mAh/g at 0.2C rate with good cyclic capability. The powder microelectrode cyclic voltammetry test indicated that the redox process of the sample had good reversibility.
