| 中文摘要 | The LiFePO4/C composite was prepared by carbothermal reduction method (CTR) with FePO4 center dot 2H(2)O, Li2CO3 as starting materials, and acetylene black or polyethylene glycol (PEG; mean molecular weight of 10,000) as carbon sources. The structural and electrochemical properties were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmittance electron microscopy (TEM), and charge-discharge tests. The results showed that LiFePO4/C is olivine-type phase, and the addition of carbon reduced the LiFePO4 grain size with uniform distribution. The carbon is dispersed between the grains, forming a good electronic contact. The synthesized LiFePO4 composites showed excellent electrochemical performance with initial discharge capacity of 161, 142 and 96mAh.g(-1) at 0.1C, 1C and 5C, respectively and displays a robust rate capacity and stable cycling life. |
