An electrical energy storage means (3) has a number of prismatic energy storage cells (1). The storage cells (1) are arranged adjacent to one another such that interfaces (4) of adjacent storage cells (1) run at a distance (a) from one another such that the interfaces (4) of the adjacent storage cells (1) form an intermediate space (5). A respective first layer (6) consisting of a compressible, flexible, and heat-conducting material is arranged between the interfaces (4) of adjacent storage cells (1), said first layer abutting one of the two interfaces (4) of the adjacent storage cells (1) under pressure. Either the respective first layer (6) also abuts the second of the two interfaces (4) of the adjacent storage cells (1) under pressure, or a second layer (8) consisting of a compressible, flexible, and heat-conducting material is arranged between the interfaces (4) of adjacent storage cells (1), said second layer abutting the second of the two interfaces (4) of the adjacent storage cells (1) under pressure. A heat-conducting device (10, 12, 10+12) is arranged in the first layer (6) or in the first layer (6) and the second layer (8) or between the first layer (6) and the second layer (8), by means of which device heat energy produced during charging and/or discharging the storage cells (1) is conducted out of the intermediate space (5) between the adjacent storage cells (1).
