  • Patent number: 5759215
    Abstract: 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.

  • Patent number: 5500583
    Abstract: 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.
