Electrolyte treatment system and method

An apparatus for removing impurities from a non-aqueous electrolyte prior to being used in an electrochemical cell;

• the apparatus comprising:
• a vessel that includes one or more chambers having an inlet and an outlet;
• the inlet configured to allow the electrolyte to enter the vessel in order for the electrolyte to flow through the one or more chambers, the outlet being in fluid communication with the electrochemical cell and configured to allow the electrolyte to exit the vessel in order to fill the electrochemical cell;
• and
• an inorganic scavenging agent located within the one or more chambers, such that the inorganic scavenging agent is held in place as the electrolyte flows there through;
• the inorganic scavenging agent comprising a mixture of one or more types of zeolite particles and at least one type of absorbent filler particles;
• wherein the mixture absorbs one or more of moisture, free transition metal ions, or hydrogen fluoride (HF) that is present as impurities in the non-aqueous electrolyte.
