Abstract:
Demand for lithium has increased due to the market for lithium-ion batteries. The two most important compounds in which lithium is traded are Li2CO3 and LiOH.
ICP-OES is used for lithium analysis as it can quickly perform multi-element analysis, handle diverse sample types, and quantify sub μg∙L-1 to % levels of impurities. In coming years, purity requirements will increase to increase battery performance. Increased purity will challenge ICP-OES methods and ICP-MS may be required.
Here, we highlight how both techniques can determine impurities in Li2CO3 and LiOH. 45 elements were analyzed using ICP-OES, whereas >60 elements were analyzed using ICP-MS.
