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,hydrothermal time,and compactedness of hydrothermal reactor on the structure of LiFePO4 was investigated in details.The results showed that the optimal reaction parameters were as follows: hydrothermal temperature 180 ℃,hydrothermal time 24 h,and compactedness 70%.
