Patent ID: 8012618

Claim:
A rechargeable battery, comprising: a cell received in a cell cup, wherein said cell has a positive pole and an elongated cylindrical shape with a jacket face, a temperature-dependent element which monitors the temperature of the cell, the temperature-dependent element at least partially surrounding the jacket face and the cell cup, and wherein the temperature-dependent element is a PTC element, said PTC element comprising: a first metal layer soldered and/or welded and/or glued on the cell cup, the first metal layer producing an electrical connection between the PTC element and the cell cup or cell, said first metal layer extending into a vicinity of the positive pole, a plastic intermediate layer adjoining the first metal layer, the intermediate layer having cold conductor properties, said plastic intermediate layer not extending as far toward the positive pole as the first metal layer, and a second metal layer covering the intermediate layer, wherein the PTC element is connected electrically to the cell cup such that a series circuit of the temperature-dependent element and the cell is effected, and wherein the second metal layer forms a new negative pole of the cell.
