摘要
研究建立了锂离子电池电极材料LiCoO2 中主成分Li的分析方法。考察了Li在原子吸收光谱和电感耦合高频等离子发射光谱上的行为。所确定的AAS及ICP AES测定方法准确、简便、快速。Li的RSD 0 .5 8%～ 0 .92 %。加标回收率AAS 98.0 %～ 10 2 .7% ;ICP AES98.6%～ 10 2 .9% 。
The analytical methods (AAS and ICP AES) of Li as main content in anode materials LiCoO 2 of lithium ion battery were presented. The research evaluates the behavior of lithium in atomic absorption spectrometry and in inductively coupled plasma atomic emission spectrometry. The method is accurate, simple and efficient. RSD of lithium is 0.58%～0.92%. The range of the recovery is 98.0%～102.7% (AAS) and 99.0%～101.0% (ICP AES). The methods are adaptable to analysie LiCoO 2.
