A method for activating the anode, cathode, and polymeric matrix components of an electrochemical cell is provided. Subsequent to forming the electrochemical cell precursor a quantity of activation fluid comprising electrolyte solvent and an inorganic salt is added into the electrochemical cell precursor at a rate such that substantially all of the activation fluid is incorporated into the electrochemical cell precursor. The method produces electrochemical cells having consistent amounts of solvent and salts therein.

Method of preparing electrochemical cells

Disclosed are methods for extending the cycle life of solid, secondary electrolytic cells employing a solid electrolyte which methods comprise (a) charging the discharged electrolytic cell at a rate of from at least about 0.1 to about 0.5 milliamp per square centimeter; (b) interrupting charging step (a) and conducting a high magnitude discharge pulse in said cell of from about 10 seconds to 2 minutes in duration; and (c) reestablishing the charging rate of step (a) and maintaining this rate until the potential of the electrolytic cell increases by at least 0.5 volts.
