ABSTRACT:
A solid electrolyte capacitor cell includes a cathode contact layer, a cathode layer of carbon and RbAg.sub.4 I.sub.5 surrounded by a peripheral portion of the cathode contact layer, a larger electrolyte layer of RbAg.sub.4 I.sub.5 attached to the cathode layer, and an anode layer of carbon and RbAg.sub.4 I.sub.5, an anode contact layer, and an insulative, annular silver barrier extending between and contacting peripheral portions of the cathode contact layer, the anode contact layer, and edges of the cathode, electrolyte, and anode layers to prevent silver migration. A composite capacitor includes a plurality of the series-connected solid electrolyte cells stacked in an elastic housing that maintains isostatic internal pressure throughout the electrolyte layers of all of the cells, making them resistant to formation of minute cracks in all of the electrolyte layers. This prevents deposition of silver in such cracks during charge/discharge cycling and therefore prevents cathode-to-anode shorts.
