Zusammenfassung:A button cell includes a housing having a metal cell cup having a cell cup plane region and a metal cell top having a cell top plane region. An electrode winding is disposed within the housing, the electrode winding having a first end side and a second end side, the electrode winding being formed from a multi-layer assembly wound in a spiral shape, the multi-layer assembly including a positive electrode formed from a current collector. A conductor is connected to the current collector, wherein the conductor at least partially lies flat between (i) the first end side of the electrode winding and (ii) a first of the cell cup plane region or the cell top plane region. The first conductor is welded to the first of the cell cup plane region or the cell top plane region. An insulator is positioned between the first conductor and the electrode winding.
