Abstract
A method of manufacturing a lithium ion battery cell. A non-aqueous liquid electrolyte solution is placed in contact with particles of a lithium ion-exchanged zeolite material for a time sufficient to remove water molecules from the liquid electrolyte solution. Thereafter, the liquid electrolyte solution may be introduced into an electrochemical cell assembly and hermetically sealed within a cell casing to form a lithium ion battery cell.
