Making LiFePO4 presoma by using chelation of C=O bond and metal ion in citric acid and taking LiNO3, NH4H2PO4, citric acid, ferrous oxalate, absolute ethyl alcohol and glycol as reactant. After maturing, through 100℃ drying and 400℃, 500℃ and 700℃ sintering, the paper was explored varying pattern of performance of anode material through compared with LiFePO4 which was added orthosilicate of metasilicic acid and polysorbate of activator-80.
