Synthesis and Electrochemical Behavior of LiFePO4-xFx (x=0.05, 0.1, 0.15, 0.2) by Solvothermal Method

摘要

The F-doped LiFePO4 material was prepared through a simple solvothermal method by applying hydrofluoric acid as the source of fluorine. The obtained LiFePO3.85F0.15 at 0.1 C and 10 C delivered a higher capacity of 153.185 and 81.972 mAh.g(-1) compared with LiFePO4 at 0.1 C and 10 C (143.351 and 48.707 mAh.g(-1)).
