In 2022,Parhizi, Mohammad; Caceres-Martinez, Louis Edwards; Modereger, Brent A.; Kenttamaa, Hilkka I.; Kilaz, Gozdem; Ostanek, Jason K. published an article in Energies (Basel, Switzerland). The title of the article was 《Determining the Composition of Carbonate Solvent Systems Used in Lithium-Ion Batteries without Salt Removal》.SDS of cas: 872-36-6 The author mentioned the following in the article:
In this work, two methods were investigated for determining the composition of carbonate solvent systems used in lithium-ion (Li-ion) battery electrolytes. One method was based on comprehensive two-dimensional gas chromatog. with electron ionization time-of-flight mass spectrometry (GCxGC/EI TOF MS), which often enables unknown compound identification by their electron ionization (EI) mass spectra. The other method was based on comprehensive two-dimensional gas chromatog. with flame ionization detection (GCxGC/FID). Both methods were used to determine the concentrations of six different commonly used carbonates in Li-ion battery electrolytes i.e., ethylene carbonate (EC), propylene carbonate (PC), di-Me carbonate (DMC), di-Et carbonate (DEC), Et Me carbonate (EMC), and vinylene carbonate (VC) in model compound mixtures (MCMs), single-blind samples (SBS), and a com. obtained electrolyte solution (COES). Both methods were found to be precise (uncertainty < 5%), accurate (error < 5%), and sensitive (limit of detection <0.12 ppm for FID and <2.7 ppm for MS). Furthermore, unlike the previously reported methods, these methods do not require removing lithium hexafluorophosphate salt (LiPF6) from the sample prior to anal. Removal of the lithium salt was avoided by diluting the electrolyte solutions prior to anal. (1000-fold dilution) and using minimal sample volumes (0.1μL) for anal. In the experiment, the researchers used many compounds, for example, Vinylene carbonate(cas: 872-36-6SDS of cas: 872-36-6)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.SDS of cas: 872-36-6
