    • 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.
    • 一种电化学能量存储装置,包括多个平面存储单元(2),每个平面存储单元在存储单元(2)的窄边上具有第一电流导体(18a)和第二电流导体(18b)。 多个间隔元件(4)各自布置在两个存储单元(2)之间,用于在存储单元(2)之间保持预定的距离; 以及夹持装置(10),用于将存储单元(2)和间隔元件(4)夹在一起以形成堆叠。 间隔元件(4)在其面向储存室(2)的两侧各自具有第一压力表面(22a)和第二压力表面(22b)。 因此,在每种情况下,存储单元(2)的一个电流导体(18a,18b)通过夹紧装置(10)的力配合被夹紧在两个间隔元件(4)的第一压力表面(22a) ),并且存储单元(2)的另一个电流导体(18b,18a)通过夹紧装置(10)的力配合夹在两个间隔元件(4)的第二压力表面(22b)之间。 在间隔元件(4)的第一压力表面(22a)和/或第二压力表面(22b)的区域中,在每种情况下,提供接触元件(26)用于形成导电连接 在间隔元件(4)的第一或第二压力表面(22a,22b)之间,最后,间隔元件(4)和/或接触元件(26)形成为使得第一压力表面 22a)之间并且在第二压力表面(22b)之间彼此一致。
