    • PURPOSE: A method for qualitatively and quantitatively analyzing trace components of an anodic material is provided to obtain a higher detection limit than the detection limit of a conventional ICP analysis method, to quickly and accurately analyze an extremely little component of an anodic active material, and to be used for battery and materials research fields. CONSTITUTION: A method for qualitatively and quantitatively analyzing trace components of a high voltage anodic material of a secondary lithium battery comprises the following steps: manufacturing an analyte sample by putting LiCoO_2 anodic active material, which is manufactured by coating TiO_2, into nitrohydrochloric acid and heating the mixture; diluting the sample for ion chromatography analysis; injecting the diluted sample into the ion chromatography and analyzing the sample; and obtaining the content of phosphate among the diluted solution by substituting a peak area with a calibration curve and drawing the content of the phosphate among the sample.
    • 目的:提供一种定性和定量分析阳极材料痕量成分的方法,以获得比常规ICP分析方法的检测限更高的检测限,快速准确地分析阳极活性物质的极少成分,以及 用于电池和材料研究领域。 构成:用于定性和定量分析二次锂电池的高电压阳极材料的痕量组分的方法包括以下步骤:通过将通过涂覆TiO 2制造的LiCoO 2阳极活性材料放入硝酸盐酸和加热来制造分析物样品 混合物; 稀释样品进行离子色谱分析; 将稀释的样品注入离子色谱并分析样品; 并通过用校准曲线取代峰面积并抽出样品中的磷酸盐的含量来获得稀释溶液中的磷酸盐含量。
