The electrical energy storage device with flat cells and spacers

An electric energy storage device comprises a plurality of flat memory cells for the storage and delivery of electrical energy with opposing flat current diverters, spacers for maintaining a predetermined distance between the memory cells and a clamping means for clamping the cells to form a stack. The spacer elements have pressure surfaces, said current conductor of the cells are clamped between the respective pressure faces of two spacer elements by means of adhesion by the tensioning means. In the area of ​​opposed pressure surfaces of a spacer a contacting for establishing an electrical connection between the opposing pressure surfaces or an insulating structure is provided either. The spacer elements are designed so that the compressions between the pressure surfaces with insulating structure and between the printing areas with contacting means are equalized to each other.
