| Abstract: | LiFePO4 was synthesized via the hydrothermal method with the starting reagents of FeSO4 · 7H2O, LiOH·H2O, and H3PO4. The as-prepared samples were characterized by using XRD and FT-IR techniques. The influence of different hydrothermal temperatures, actor on the structure of LiFePQ was investigated in hydrothermal time, and compactedness of hydrothermal redetails. The results showed that the optimal reaction param- eters were as follows： hydrothermal temperature 180 ℃, hydrothermal time 24 h, and compactedness 70%. |
