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.
