Rechargeable secondary battery having improved safety against puncture and collapse

摘要

Aspects of embodiments of the present invention are directed toward a rechargeable secondary battery having improved safety against puncture and collapse. Consequently, a rechargeable battery (100) is provided, comprising an electrode assembly (110) having a first electrode plate (111), a second electrode (112) plate, and a separator (113) interposed between the first and the second electrodes plates (111, 112), a case (120) for mounting the electrode assembly (110) therein and a cap plate (150) for closing an opening of the case (120). A short-circuit induction member (160) is provided being electrically connected to the electrode assembly (110) and being arranged between the case (120) and the electrode assembly (110). The short-circuit induction member (160) is adapted to form a short-circuit of the electrode assembly (110).
