    摘要： An electrochemical energy storage element includes an electrode-separator assembly enclosed in a housing that includes a closure assembly. The closure assembly includes a first sheet metal part having a first side, an opposite second side, and an aperture. The closure assembly also includes a second sheet metal part having a contact segment extending on the first side of the first sheet metal part, a fixing segment extending on the second side of the first sheet metal part, and a tubular feedthrough connecting the connecting the contact segment and the fixing segment through the aperture. An electrically insulating seal is disposed between the first sheet metal part and the second sheet metal part. A first part of the fixing segment is formed as a bottom that closes the tubular feedthrough on the second side of the first sheet metal part.

    摘要： An energy storage element includes a cathode including a cathode current collector with a main region and a free edge strip and an anode including an anode current collector with a main region and a free edge strip. The energy storage element also includes first and second contact sheet metal members in direct contact with the free edge strips. The cathode and the anode are separated by a separator or a solid electrolyte layer and are arranged relative to one another such that one free edge strip protrudes from one side of an assembly including the cathode and the anode and the other free edge strip protrudes from the other side. At least one free edge strips has, as a result of a folding and/or a rolling-up process, a thickness that corresponds at least to the thickness of the associated cathode or anode in an adjacent main region.

    摘要： An energy storage element includes a housing enclosing an interior space, which housing is formed of a first metal housing part and a second metal housing part and has a substantially circular upper side and a substantially circular lower side spaced from one another and parallel to one another, and an annular housing side that connects the upper side and the lower side; a winding arranged in the interior, which winding includes a strip-shaped positive and a strip-shaped negative electrode and a strip-shaped separator arranged between the electrodes that are wound in a spiral around a winding axis; wherein the winding has a first end face and a second end face and an annularly circumferential winding outer side, the first and second end faces face in the direction of the circular and mutually parallel upper side and lower side such that the winding axis is oriented perpendicular or at least substantially perpendicular to the upper side and the lower side, and the winding has an axial cavity through which the winding axis runs; and an electrically conductive pin arranged in the cavity and electrically connects one of the electrodes of the winding to one of the housing parts, wherein the first and the second housing part are designed such that they are able moveable against each other along an axis running vertically through the circular upper side and the circular lower side of the housing, and the pin is configured such that the electrical contact to one of the electrodes of the winding is broken when the housing parts move away from one another along the axis.
