Analysis of Contaminants in Low Viscosity Solvents for Electrolytes in Liquid-LIB by GC-TOFMS
Introduction
The electrolyte in a lithium-ion battery (LIB) is made by dissolving the electrolyte in a liquid mixture of ethylene carbonate (EC) and various low-viscosity solvents. Producing a high purity electrolyte requires a high purity solvent and therefore it is important to have a good understanding of the composition of impurities in the solvent.JEOL's latest analytical software, msFineAnalysis AI, is designed for rapid analysis of GC-HRMS data acquired by both EI and SI, chemical formula determination, and chemical structure prediction. This application note reports a qualitative analysis of impurity components of dimethyl carbonate (DMC), which is commonly used as a solvent in electrolytes, as a case study of msFineAnalysis AI analysis.
