Abstract

An electrical energy storage device includes prismatic energy storage cells arranged adjacent to one another such that interfaces of adjacent storage cells run at a distance from one another such that the interfaces of the adjacent storage cells form an intermediate space. A respective first layer is arranged between the interfaces of adjacent storage cells, the first layer abutting one of the two interfaces of the adjacent storage cells under pressure. Either the respective first layer also abuts the second of the two interfaces of the adjacent storage cells under pressure, or a second layer is arranged between the interfaces of adjacent storage cells, the second layer abutting the second of the two interfaces of the adjacent storage cells under pressure. A heat-conducting device is arranged in or between the first layer and the second layer is conducted out of the intermediate space between the adjacent storage cells.
