Abstract: |
A polycrystalline LiFePO4 powder with olivine structure is prepared from Fe(Ac)2, FeSO4.7H2O, Ba(Ac)2 and organic acid by the sol-gel method. Its advantages are short period, low burning temp., low energy consumption, high purity and electric conductivity, and high granularity uniformity. It is suitable for making Li-ion battery. |
