NOVELTY - Energy storage module (1) comprises a number of prismatic storage cells (2), each having one front side (3) on which at least one power tap (4) is arranged and one rear side (5), which is opposite to the front side; and a longitudinal support having two opposite outside walls. At least one storage cell contacts each outside wall by the rear side.    USE - The energy storage module is useful for the voltage supply of a motor vehicle (claimed).    ADVANTAGE - The energy storage module: is safe to operate; has cost-efficient production and assembly; and ensures optimal cooling of the individual storage cell.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) an energy storage arrangement comprising at least two energy storage modules, and at least one cross member, where cross member is fixed to the longitudinal support of at least two energy storage modules;    (2) a motor vehicle comprising the energy storage module and/or an energy storage arrangement, where the largest surface of the prismatic storage cells are arranged horizontally in the motor vehicle; and    (3) producing an energy storage module, comprising providing at least two prismatic storage cells having a front surface on which at least one power-tap is arranged, and a rear side opposite to the front side, bonding at least two storage cells to a common film, where storage cells are adhered to its rear side, providing a longitudinal support having two opposing outside walls, and exposing the film with the storage cells affixed to the longitudinal support, so that each outside wall of at least one storage cell is applied with its rear side, or providing at least two prismatic storage cells, bonding at least one first storage cell to a first film and at least one second storage cell to a second film, where storage cells are adhered to its rear side, and placing the first film with the glued first storage cell on a first outside wall the longitudinal support and the second film with the affixed second storage cell on a second outside wall the longitudinal support.
