6. A button cell closed without flanging comprising:
-
a housing formed of two housing halves comprising a cell cup and a cell lid, an electrically insulating seal separating the cell cup and the cell lid, an electrode-separator assembly comprising at least one positive and at least one negative electrode arranged inside the housing, metal diverters electrically connecting the at least one positive and the at least one negative electrode to the housing halves, and a thermal fuse connected to or integrated into one of the diverters, wherein the cell cup comprises a bottom region, a shell region, a border region arranged between the bottom region and the shell region, and a cut edge, the cell lid comprises a lid region, a shell region, a border region arranged between the lid region and the shell region, and a cut edge, the cell lid is inserted into the cell cup, the shell region of the cell cup has a substantially constant radius in a direction of the cut edge, the housing formed by the cell cup and the cell lid has a substantially planar bottom region and a substantially planar lid region substantially parallel thereto, and the assembly is present as a winding whose end face sides point in a direction of the planar bottom region and the planar lid region. - View Dependent Claims (7, 8, 9, 10, 12)

11. A button cell comprising:
-
two metal housing halves separated from one another by an electrically insulating seal and which form a housing having a substantially planar bottom region and a planar lid region parallel thereto, an electrode-separator assembly having at least one positive and at least one negative electrode within the housing, wherein the assembly is a winding whose end face sides point in a direction of the planar bottom region and the planar lid region, and metal diverters which electrically connect the at least one positive and the at least one negative electrode to in each case one of the housing halves, wherein at least one of the diverters is provided with a thermal fuse.
