Electrochemical energy store, process for the preparation of such electrochemical energy storage battery and having a plurality of such electrochemical energy storage

The invention relates to an electrochemical energy storage (1) having an electrode foil arrangement of a foil-like sheath (1.1) is surrounded, at least two arrester (2) from the envelope (1.1) are led out, and surrounded a with the envelope (1.1) electrode foil arrangement at least partially surrounding the holding frame (4) is peripherally provided. According to the invention, the holding frame (4) dimensions, that an inner surface (4.1) of the holding frame (4) at least in sections with a predetermined distance to a peripheral edge region (1.2) of the foil-like sheath (1.1) being spaced apart and in a space formed by the distance of free space (S), an electrically insulating filling material (6) is arranged. Furthermore, the invention relates to a method for manufacturing such electrochemical energy store (1) and a battery having a plurality of such electrically of interconnected electrochemical energy storage (1).
