| Abstract: | Determination of Ni, Co and Mn elements in Li-ion battery cathode materials LiNi1-x-yCoxMnyO2 was studied by ICP-OES. Analytical conditions were investigated and optimized through adjusting the direction of observation, choosing appropriate dilution multiple and adopting the secondary sensitive wavelengths of Ni, Co and Mn for the determination of corresponding elements with high contents The results showed that the method has good accuracy and precision with 97.4%~103.0% recovery. The relative standard deviation (RSD) was below 1%. The method is suitable for the determination of Ni, Co and Mn in industrial production for quality analysis. |
