Zusammenfassung:	A button cell with a housing includes a cup part and a cover part, which each have a floor region and a lateral surface region adjacent thereto and extending up to a first cut edge. A positive and a negative electrode, separated by a separator, are arranged in the housing. The cup part and the cover part are physically separated and electrically isolated from one another by a film seal, wherein the film seal surrounds the outer side of the cover part in the lateral surface region like a collar and is turned over the cut edge of the cover part inwardly. The film seal in this case forms, together with the separator and the cover part, a closed cavity in which the negative electrode is arranged.
