Anion Analysis in Lithium Salts (3) (SI-90 4E)

Lithium tetrafluoroborate, lithium hexafluorophosphate and lithium perchlorate are used as an electrolyte of a lithium ion secondary battery. In this application, the anions of these salts were analyzed using IC SI-90 4E, an anion analysis column for non-suppressor method.
