[Analysis Case] Identification and Quantitative Evaluation of Solvents and Additives in LIB Electrolytes

Qualitative and quantitative evaluation is possible from the sampling of the electrolyte.

The electrolyte of lithium-ion secondary batteries can be qualitatively and quantitatively analyzed using GC/MS. In the example below, ethylene carbonate (EC) and ethyl methyl carbonate (EMC) were identified as organic solvents, and vinylene carbonate (VC) was identified as an additive. It is also possible to determine the composition ratio of the solvents and the content of the additives. Additionally, other additives such as fluoroethylene carbonate (FEC) and ethylene sulfite (ES) can also be evaluated.
