    • A button cell includes a sealed housing including a cup having a base, a circumferential sleeve, an intermediate region connecting the base and sleeve, and a cut edge, a cover having a base, a circumferential sleeve, and a cut edge, and a seal, wherein the cover is arranged with the cut edge in front into the cup, and the seal between the cup and cover is arranged such that it isolates them from each other, and wherein the sleeve of the cover is divided into a single-walled section and an adjoining circumferential double-walled opening edge with a U-shaped cross-section formed by bending the cut edge of the cover radially outwardly, the sleeve of the cover has a circumferential notch directly below the circumferential double-walled opening edge, in which its external diameter has a minimum value, and the sleeve of the cup has a circumferential protuberance formed by radial drawing-in.

    • 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.
    • 具有壳体的按钮单元包括杯部分和盖部分,每个部分具有与其相邻并且延伸到第一切割边缘的底面区域和侧表面区域。 由隔膜隔开的正电极和负电极布置在壳体中。 杯部分和盖部分通过膜密封物理分离并彼此电隔离,其中膜密封件围绕侧部表面区域中的盖部分的外侧如套环一样被覆盖, 覆盖部分向内。 在这种情况下,薄膜密封件与分离器和盖部分一起形成其中布置有负极的封闭空腔。
