Abstract
An apparatus, system, and method for removing impurities from a non-aqueous electrolyte used in an electrochemical cell. The apparatus includes a vessel having one or more chambers with an inlet and an outlet configured to allow the flow of the electrolyte through the one or more chambers; and an inorganic scavenging agent located within the one or more chambers. The inorganic scavenging agent includes one or more types of zeolite particles, at least one type of absorbent filler particles, or a combination of the zeolite and absorbent filler particles. The inorganic scavenging agent absorbs one or more of moisture, free transition metal ions, or hydrogen fluoride (HF) that is present as impurities in the non-aqueous electrolyte.
