Synthesis of LiFePO4 Cathode Materials by a Chemical Method

Abstract:

Article Preview

The olivine-type LiFePO4 powder was prepared by a chemical method using the synthesized FePO4 1.78H2O, LiOH, citric acid and PEG as raw materials. The synthesized FePO4 1.78H2O precursor powder was obtained by co-precipitation method. LiFePO4 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 LiFePO4 was in a single phase when fabricated by using the synthesized FePO4 1.78H2O powder at pH of 3.5 in argon atmosphere.
