Single Cell and Battery Made of a Plurality of Single Cells

A single cell for a battery, comprising:

• an electrode stack;
• a cell housing in which the electrode stack is situated, wherein the cell housing is formed from first and second electrically conductive shell-shaped housing side walls situated in parallel opposite one another, each of the first and second electrically conductive shell-shaped housing side walls having a shell flange extending around edges of the first and second electrically conductive shell-shaped housing side walls,
• wherein the shell flanges of the first and second electrically conductive shell-shaped housing side walls are joined to one another in an integrally bonded manner to form a flange area and each of the first and second electrically conductive shell-shaped housing side walls being electrically insulated from one another,
• wherein pole contact tabs of the electrode stack are electrically connected to the first and second electrically conductive shell-shaped housing side walls,
• wherein at least one of the first and second electrically conductive shell-shaped housing side walls has a section protruding, at least in parts, beyond the flange area of at least one housing edge of the cell housing, wherein the protruding section of the at least one of the first and second electrically conductive shell-shaped housing side walls is angled in a direction of a cell interior and in a direction of a shell base of the first and second electrically conductive shell-shaped housing side walls, and in the angled state protruding beyond the shell base by a predetermined amount.
