An electrode winding disposed within the housing is formed from a multi-layer assembly that is wound in a spiral shape about an axis. The multi-layer assembly including a positive electrode, a negative electrode, and a separator disposed between the electrodes. A first conductor is provided that includes a strip-shaped portion that lies flat between a first end side of the electrode winding and a first of the cell cup and cell top. A second conductor is provided that includes a strip-shaped second portion that lies flat between a second end side of the electrode winding and a second of the cell cup and cell top. The first conductor and the second conductor are metal foils.",
