ABSTRACT:
A flat capacitor is manufactured by placing an anode foil within a fold of spacer within a folded cathode foil, impregnating with electrolyte, and heat-sealing between layers of heat-sealable polymer. The foils have electrode tabs attached thereto that are spaced laterally from each other and extend beyond the same edges of the polymer. Leads are attached to the tabs external to the sealed polymer edges.
