Benefits of ICP-MS for the Elemental Compositional Analysis of Lithium-Ion Battery Electrolytes

This month’s column investigates the elemental composition of electrolytes in lithium-ion batteries (LIBs) using inductively coupled plasma–mass spectrometry (ICP-MS). In addition to offering quantitative results for the target elements, the technique also provided valuable insight into the semiquantitative analysis of up to 78 elements in the samples. To complete the study, method detection limits and long-term stability in LIB electrolyte matrices were also evaluated.
