An electrochemical energy storage device comprises a plurality of flat storage cells (2) each having a first current conductor (18a) and a second current conductor (18b) on a narrow side of the storage cell (2); a plurality of spacing elements (4) each being arranged between two storage cells (2) for maintaining a predetermined distance between the storage cells (2); and a clamping means (10) for clamping the storage cells (2) and spacing elements (4) together to form a stack. The spacing elements (4) each have a first pressure surface (22a) and a second pressure surface (22b) on their two sides facing a storage cell (2). Thereby, in each case, the one current conductor (18a, 18b) of the storage cells (2) is clamped between the first pressure surface (22a) of two spacing elements (4) by means of force fit by the clamping means (10), and the other current conductor (18b, 18a) of the storage cells (2) is clamped between the second pressure surfaces (22b) of two spacing elements (4) by means of force fit by the clamping means (10). In the region of the first pressure surfaces (22a) and/or in the region of the second pressure surfaces (22b) of a spacing element (4), in each case a contact element (26) is provided for making an electrically conductive connection between the first or second pressure surfaces (22a, 22b) of a spacing element (4), and finally, the spacing elements (4) and/or the contact elements (26) are formed such that the compressions between the first pressure surfaces (22a) and between the second pressure surfaces (22b) are conformed to one another. |
