ABSTRACT:
A method of making a lithium electrochemical cell includes treating the cathode active material with an agent that includes lithium but not sodium. A cathode including the cathode active material, an anode, a separator, and an electrolyte are assembled in a housing to provide a cell containing less than 1500 ppm by weight of sodium.
