Effect on the Characteristic and Properties of Carbon Coated LiFePO4/C Composite
LiFePO4/C composite with different types of organic carbon sources has been synthesized by carbon thermal reduction technique. The physical characteristics and electrochemical properties of LiFePO4/C composite have been studied compared with commercial products. It is shown that good carbon-coated LiFePO4/C composite can be obtained with 13wt.% glucose as carbon source, which has effected on the good processing performance due to its suitable specific surface area of 26.3m2/g and high tap density of 1.3g/cm3. Furthermore, it has contributed to the high-rate electrochemical property with discharge capacity of 128mAh/g at 1C (1C=170 mAh/g).
