The composition and content of carbonates, such as dimethyl carbonate and ethyl methyl carbonate, in electrolytic solution plays an important role in the development and quality control of lithium ion batteries. Monitoring the composition and ratio of carbonates has important implications for energy density, cycle life and the safety of lithium ion batteries.
Download this application note for a reliable methodology for the determination of nine carbonates found in lithium ion battery electrolytes. Utilizing a Clarus® SQ 8 GC/MS with EI source, this method offers precise results with the recovery, linearity and detection limits required by users in the lithium ion battery industry.
