Abstract

A battery cell (2) with a film cover (4) for electrochemically active material, wherein the film cover (4) is present substantially in a prismatic shape, and therefore the film cover (4) can be assigned two mutually opposite main surfaces (6a, b), and with current collectors (10a, b) which electrically contact the electrochemically active material and serve for the interconnection of the battery cell (2). At least one current collector (10a, b) has a flat element (12a, b) which substantially covers a main surface (6a, b) of the film cover (4) and has a connection region for connection to a cooling device, or is provided with cooling ducts.
