AU002026: Determination of Tetrafluoroborate, Perchlorate, and Hexafluorophosphate in an Electrolyte Sample for Lithium-Ion Battery Production Be the first to rate this application


This application demonstrated an improved method for the determination of tetrafluoroborate, perchlorate, and hexafluorophosphate in simulated lithium-ion battery production samples using a RFIC system with suppressed conductivity detection, and 2 mm versions of Dionex IonPac AS20 columns. This method significantly reduces eluent consumption and thus prolongs the life of the EGC as flow rate is reduced from 1.2 to 0.3 mL/min. The method has a linear calibration over the concentration range of 1 to 40 mg/L and was shown to be precise and accurate.
