摘要：
The olivine-type LiFePO(4) powder was prepared by a chemical method using the synthesized FePO(4)center dot 1.78H(2)O, LiOH, citric acid and PEG as raw materials. The synthesized FePO(4)center dot 1.78H(2)O precursor powder was obtained by co-precipitation method. LiFePO(4) powder was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermo-gravimetric analysis (TGA)/differential scanning calorimetry (DSC). The results showed that the calcined LiFePO(4) was in a single phase when fabricated by using the synthesized FePO(4)center dot 1.78H(2)O powder at pH of 3.5 in argon atmosphere.
