According to the performance tests of LiFePO4 prepared by different iron sources, the product of Fe(NO3)3 had a pure phase and good electrochemical performances, while the raw material is cheaper, so Fe(NO3)3 was choosen as the iron source. The best determination of the experiment was that the lithium:iron ratio was 1, the carbon source content was 10 %, the sintering temperature was 700 °C for 6 h, and the sintering process was undertaken in a nitrogen atmosphere. The results showed that the initial discharge capacity of LiFePO4 synthesized in such conditions was 118 mAh/g in 2.5–4.2 V and at 0.1 C rate, and the capacity experienced almost no loss after 20 circulations.
