| Abstract: | LiFe1-xCoxPO4/C （ x = 0, 0.05, 0.1 ）, positive material was synthesized for Li - ion batteries by sol - gel method with Fe （III） salt as Fe source and with PEG - 400 as assistant. The effect of different amount of Co. or, the crystal structure, morphology and electrochemical performance of the samples of LiFePO4/C were studied by XRD, SEM and galvanostatic charge -discharge methods. |
