摘要:
The invention relates to an electrical energy storage device comprising: a plurality of flat storage cells for storing and discharging electrical energy, having opposing, flat current conductors, a plurality of spacer elements for maintaining a predetermined distance between the storage cells, and a clamping means for clamping the cells into a stack, wherein cells are clamped by the clamping means at the current conductors thereof between spacer elements by means of a force fit, wherein at least some of the spacer elements are designed as heat sinks. The heat sinks have fins extending sideways out from the stack. The heat sinks are alternatively thermally connected to the current conductors by means of a soft, heat conductive material. In a further alternative, two heat sinks are disposed between adjacent current conductors. In a final alternative, the spacer elements comprise relief holes for weight reduction. The alternatives can be combined.

The invention relates to a galvanic cell (101, 401) having arresters (407, 408) and heat sinks (103, 104, 105, 106, 403, 404, 405, 406) attached thereto. Said heat sinks are designed such that the arrester can be used simultaneously for transporting electrical energy into the cell or out of the cell, and also for removing heat from the cell. The heat sink for cooling galvanic cells is designed such that same can be attached to an arrester of a galvanic cell by force closure, form closure, or adhesive force closure such that the arrester can be used simultaneously for transporting electrical energy into the cell or out of the cell, and also for removing heat from the cell.

A profile strip to border an electrochemical energy storage device having at least one, essentially, longitudinally extending first recess, which is bordered by a first arm and a second arm. The first and the second arm are made such that they are attachable to opposite sides of an boundary area of the electrochemical energy storage device, and at least partially connected to each other with a backside part. In a method of producing such a profile strip for an electrochemical energy storage device, at least one first recess is inserted into the profile strip by a suitable method, and the profile strip is converted in said first recess from a first, stretched, state into a second, angled, state. The corner resulting from bending may have a connection by force-fit or by material engagement.
