Abstract:
Electrolyte analysis in batteries is crucial for verifying composition and detecting impurities. Gas chromatography mass spectrometry (GC-MS) is ideal for this due to the volatile nature of electrolyte components. However, electrolytes can't be injected directly because of the conducting salt, LiPF6, which must be removed first. An automated workflow for analyzing unprocessed electrolytes in lithium-ion batteries is proposed by means of the Thermo Scientific™ TriPlus™ RSH SMART robotic autosampler. This automated process includes removing LiPF6 via precipitation and centrifugation, and diluting to various levels for GC-MS analysis of major components, additives, and degradation products.
