Abstract
A storage device for electric energy according to an aspect of the invention comprises a plurality of flat storage cells, wherein a plurality of storage cells are stacked in a stacking direction into a cell block and are held together by a tensioning device between two pressure plates, and wherein the storage cells are connected to each other within the cell block in parallel and/or in series. Each storage cell is held in the edge region thereof between two frame elements. According to another aspect, each storage cell comprises current conductors in the edge region and electric contacting between current conductors of successive storage cells is carried out via the tensioning device by way of a non-positive fit.
