Dionex announces an IC method for the determination of lithium salts in simulated electrolyte samples from lithium ion battery production. Application Note 258: Determination of Tetrafluoroborate, Perchlorate, and Hexafluorophosphate in a Simulated Electrolyte Sample from Lithium Ion Battery Production demonstrates the accurate determination of anionic content in simulated electrolyte samples using a Reagent-Free^TM (RFIC^TM) IC system and the IonPac® AS20 column set with potassium hydroxide mobile phase.

Lithium ion batteries are commonly used in portable consumer electronic devices. The electrolyte solution in these batteries consists of a lithium salt in an organic solvent. The electrolyte's concentration in the solvent ranges from 0.1 to 2 mol/L, with an optimal range of 0.8-1.2 mol/L. The method demonstrated in AN 258 avoids the problems encountered in eluent preparation and delivers excellent retention time reproducibility for easy and reproducible quantification in the analysis of lithium ion battery electrolyte solutions.
