Abstract

A round cell rechargeable battery includes a plurality of round cells arranged next to one another and a dissipation element that is electrically insulated from the round cells and connects a group of round cells in thermally-conductive fashion so as to dissipate heat. The dissipation element is in the form of a rod and is bent in such a way that it runs in zigzag fashion alternately in each case along a lower side, an adjoining side wall, and an upper side of the round cells. The battery also includes an electrically-insulating, thermally-conductive, rubber-elastic thermoplastic elastomer, which is arranged at least partially between the dissipation element and the round cells to insulate the dissipation element electrically from the round cells and to dissipate heat from the round cells to the dissipation element.
