摘要
采用热重(TG)单曲线经验法、热重(TG)对比曲线法,以及碳-硫(C-S)测试仪测试了磷酸铁锂电极的碳含量,并对三种方法的测试结果进行了比较。研究表明,文献中常采用的热重(TG)测试方法会导致磷酸铁锂电极碳含量的估算值偏高。
TG single curve experiential method, TG experimental comparison method and C-S measurement were adopted to measure carbon contents of LiFePO4 electrodes. The compared study on carbon contents of electrodes by different methods was carried out. It is indicated that both TG single curve experiential method and TG experimental comparison method will lead to a higher estimated value on carbon contents of LiFePO4 electrode.
