Electrochemical energy storage, method for producing such an electrochemical energy storage and battery with a number of such electrochemical energy storage

摘要

The invention relates to an electrochemical energy store (1) with an electrode foil arrangement which is surrounded by a foil-like sheath (1.1), wherein at least two arresters (2) are led out of the sheath (1.1) and one surrounded by the sheath (1.1) Electrode sheet assembly at least partially surrounding frame holding frame (4) is provided. According to the invention, the holding frame (4) has dimensions such that an inner surface (4.1) of the holding frame (4) is spaced at least in sections at a predetermined distance from a peripheral edge region (1.2) of the film-like casing (1.1) and in a free space formed by the distance (S) an electrically insulating filler material (6) is arranged. Furthermore, the invention relates to a method for producing such an electrochemical energy store (1) and a battery having a plurality of such electrically interconnected electrochemical energy store (1).
