摘　　要：锂离子电池中电解质常用的锂盐为六氟磷酸锂。随着锂盐的技术发展,引入了有机锂盐,常用的锂盐含量测试方法为离子色谱法。通过对含有多种锂盐的样品进行定量分析,对测试结果进行了研究讨论,希望通过光谱和色谱联合的方法对电解液中锂盐的含量进行准确测定。The lithium salt commonly used in electrolytes in lithium-ion batteries was lithium hexafluorophosphate.With the development of lithium salt technology,organic lithium was introduced,and the commonly used method for lithium salt content measurement was ion chromatography.Through quantitative analysis of samples containing various lithium salts,the test results were studied and discussed.It is hoped that the content of lithium salts in electrolyte can be accurately determined by the combination of spectra and chromatography.
