摘要

The battery (1) has individual cells (4) enclosed and surrounded by a housing (3), and a pressure relief valve (5) arranged in the housing. The pressure relief valve is arranged in a housing frame (3.3) that connects upper and lower housing sides (3.1, 3.2) circumferentially. The pressure relief valve is formed by multiple breaking regions (3.3.1) that are inserted in the housing frame. The pressure relief valve is formed in respective breaking regions of the housing frame by a cavity, recess (6), a predetermined breaking point and an opening provided with a safety membrane e.g. breaking foil.
