Abstract:
The electric energy storage cell according to the invention is provided with: an active part, which is designed and adapted to store electric energy supplied externally and to release stored electric energy to the exterior; a casing consisting of a film material, which surrounds the active part in a gas- and liquid-tight manner; and at least two current collectors that are connected to the active part and are designed and adapted to supply electric current externally to the active part and to release electric current from the active part to the exterior. According to the invention, the part that is surrounded by the casing follows the contours of a prismatic structure with a substantially parallelepipedal form, said structure extending to a substantially lesser extent in a first spatial direction than in the other two remaining spatial directions and substantially defining two opposing, parallel flat faces and four narrow faces that connect the two flat faces. The first and the second current collectors project from the casing parallel to the planes of the two flat faces in opposite directions from two opposing narrow faces. The extension of said first and second current collector along the narrow faces from which they project is greater than half the length of said narrow faces.
