摘要
采用化学分析法对锂离子电池正极材料中的高含量锰进行测定。探讨了在大量干扰元素镍、钴存在下的测定条件。结果表明:该方法准确,精密度高,标准偏差不大于0.070,变异系数小于0.15%,回收率为99.63%～100.50%。
The chemical analysis method was used to determine high content Mn in Li-ion battery cathode material. The determination conditions with interfering elements of high content Ni and Co were discussed. The results showed that the method was accurate and precise. The standard deviation was no more than 0.070, the coefficient of variation was below 0.15%, the recovery ratio was 99.63% - 100.50%.
