Abstract: The invention relates to a battery cell, in particular a lithium-ion battery cell, wherein compared to conventional battery cells, a number of components can be reduced. The battery cell has at least one winding element, two current collectors each electrically connected to one of the electrodes of the winding element, and a metal housing. In order to be able to establish an electrical contact between one of the electrodes of the winding element and the housing, one of the current collectors is specifically configured and arranged such that said current collector is in direct mechanical and electrically conductive contact with the housing. To this end, said housing contact current collector (29) can be provided with a suitably wide plate-shaped area (35), which in edge regions (37) that are bent away at a right angle can rest against an interior wall of the housing of the battery cell in a planar manner, and can establish an electrical contact therewith.

Abstract: The invention relates to a battery cell, in particular a lithium-ion battery cell, wherein a cover plate (23) forming a part of a battery cell housing, which is designed as a plane sheet in a conventional manner, is modified to avoid short circuits between the poles of the battery cell due to moisture, for example. To this end, the cover plate (23) is provided with a central area (33) and an edge area (35) surrounding said central area (33). The central area (33) is located above an opening (14) to be closed off by the cover plate (23) of a container (13) forming a part of the battery cell housing, whereas the edge area (35) extends inside said opening (14). Thus, occurring moisture can drain off the platform-like raised central area (33) sideways toward a channel (37) in the edge area (35), and evaporate from there.

The first holder is connected here to the tubular base body at a first fastening point of the tubular base body. The second holder is also connected to the tubular base body at a second fastening point of the tubular base body. The tubular base body has at least one bend at least between the first fastening point and the second fastening point. A base body having a meandering pattern may be implemented in this way, enabling adjustment of thermal changes in the length of a cylinder head on which the fuel distributor is mounted.

Abstract: A battery (e.g., lithium-ion) cell having fewer components than conventional cells. A metallic housing, having a winding element, two current collectors, and an electrolyte, is closed off in a gas- and pressure-tight manner with a cover assembly having a cover plate by which a housing opening is largely closed off. A click spring area (formable in this plate) has a smaller thickness than surrounding areas of the plate, and can snap from a first state, in which the click spring area is bent inwardly into the housing, into a second state in which the click spring area is bent outwardly from the housing when a threshold internal pressure in the housing is exceeded, and establishes an electrical connection between the plate and a current collector. When there is a pressure rise in the housing due to temperature, for example, the battery cell may be deactivated in a targeted manner.
