摘要:
A single cell for a battery includes an electrode foil stack situated in a housing formed from two enveloping metal sheets and a frame that electrically insulates the two enveloping metal sheets from one another. Current discharge tabs of electrode foils of one polarity are connected to one another to form a pole contact, and the respective pole contact is connected to an enveloping metal sheet, and an enveloping metal sheet in each case forms an electrical pole of the single cell. The current discharge tabs of the same polarity are led out in each case at a pole side of the electrode foil stack and connected to one another in a middle area of the pole side. The pole contacts are angled parallel to the pole side, in particular with respect to one-half of the particular pole side, and are connected to an enveloping metal sheet.
