Abstract:
| In lithium-ion batteries, the electrolyte provides a conductive medium for lithium ions to move between electrodes. Degradation mechanisms are often unknown, with no reference materials available. Research has used low-resolution gas chromatography–mass spectrometry (GC-MS), nuclear magnetic resonance (NMR), and other techniques to identify compounds. This study shows the identification of known carbonate dimers using GC-HRAM-MS as part of a targeted analysis. The objective was to identify carbonate substructures by detecting known species and screening for lower abundance related compounds through accurate mass fragmentation and chromatographic features. |
