ELECTROCHEMICAL ENERGY STORAGE DEVICE

摘要

A storage device for electric energy according to an aspect of the invention comprises a plurality of flat storage cells (2), wherein a plurality of storage cells (2) are stacked in a stacking direction into a cell block (1) and are held together by a tensioning device (22, 24, 26, 222) between two pressure plates (18, 20), and wherein the storage cells (2) are connected to each other within the cell block (1) in parallel and/or in series. Each storage cell (2) is held in the edge region (6) thereof between two frame elements (12, 14, 16). According to another aspect, each storage cell comprises current conductors (8, 10) in the edge region (6) and electric contacting between current conductors (8, 10) of successive storage cells (2) is carried out via the tensioning device (22, 24, 26, 222) by way of a non-positive fit.
