ABSTRACT:
An aluminum electrolyte capacitor is provided composed of two aluminum foils between which spacers saturated with the operating electrolyte are arranged. Terminal elements are riveted and/or welded to the foils. The anode foil provided with the dielectrically acting oxide layer may potentially be produced from a larger, formed foil web. The non-formed cut edges of the aluminum foil as well as the terminal elements are covered with a fine-grained, electrolyte-compatible material. As a result thereof, the maximum operating voltage U.sub.max of traditional operating electrolytes is boosted.
