【摘要】 为了获得颗粒均匀和优异电化学性能的LiFePO4,采用不同锂源用碳热还原法合成了LiFePO4正极材料。利用XRD进行结构表征,通过充放电测试电化学性能。结果显示:以乙酸锂为锂源制得的样品颗粒粒径最小、电化学性能最佳。
【Abstract】 In order to obtain fine-particle LiFePO4 with excellent electrochemical performance,different Li sources with carbothermal reduction methods were used to synthesis LiFePO4 cathode material.LiFePO4 cathode material were characterized by X-ray powder diffraction and the electrochemical properties were investigated by charge-discharge tests.The results showed that the sample,synthesized by CH3COOLi·2H2O,had the smallest particle size and the best electrochemical performance.
【Key words】 Lithium iron phosphate; CH3COOLi·2H2O; carbothermal reduction; cathode material;
