Disclosed are methods for extending the cycle life of solid, secondary electrolytic cells employing a solid electrolyte. Also disclosed are solid electrolytes comprising from greater than 80 to about 92 weight percent of electrolytic solvents which, when employed in solid, secondary electrolytic cells extend the cycle life of the cells as compared to solid, secondary electrolytic cells employing solid electrolytes having less solvent.
