LiFePO4/C复合材料中的碳源研究
Carbon source in LiFePO4/C composite cathode material
摘要
Abstract
Olivine LiFePO4/C composite cathode materials were synthesized by a solid state method using sucrose,phenolic resin and polypropylene as carbon sources respectively. The effects of different carbon sources on the performance of as-synthesized cathode materials were investigated and analyzed. The crystal structure and the electrochemical performance were characterized by XRD, SEM, Raman spectrum, charge-discharge testing and AC impedance. The results demonstrate that the composite material carbon-coated by polypropylene has the most excellent electrochemical performance which has an initiative capacity of 154.9 mAh/g at 0.1 Cand 131.3 mAh/g at 2 Cand the capacity is 130.1 mAh/g after 30 cycles at 2 C.关键词
