Embodiment Construction

[0037] exist figure 1 A battery cell is shown schematically in and generally indicated at 10 . The battery cell 10 has a cell housing 12 with a housing container 14 and a housing cover 16 . For example in figure 1 A single-cell coil, not shown in FIG. Aluminum and copper foils are coated with active cathode and anode materials. Furthermore, the electrolyte material, for example surrounding the electrodes of the cell coil, is located in the inner region of the housing container 14 . The electrode contacting of the single-cell coils takes place via electrical contacts welded from copper and / or aluminum. exist figure 1Electrical contacts, not shown in FIG. 2 , extend from the electrodes arranged in the inner region of the housing container 14 through the housing cover 16 into the region outside the cell housing 12 .

[0038] When constructing the battery cell 10 , care must be taken to securely seal the cell housing 12 . For example, it must be prevented that the electroly...
