摘要
对制备橄榄石型锂离子电池正极材料LiFePO4进行了实验研究,采用固相合成法合成了LiFePO4和掺杂碳的LiFePO4正极材料。分析测试结果表明:掺杂碳的LiFePO4作为正极材料具有良好的电化学性能,在0.1C倍率下放电,其室温初始放电容量为130mA·h/g,循环10次后几乎没有衰减。
Test is made on olivine LiFePO_4 anode material for lithium-ion battery.LiFePO_4 and carbon-doped LiFePO_4 were prepared by solid-phase synthesization. Test results showed that carbon-doped LiFePO_4 had good electrochemical performance.Discharging at 0.1 C rate,the initial discharge capacity was 130 mA·h/g with little capacity decrease after 10 circles at room temperature.
