Abstract
Official abstract text for this publication.
Provided is a sealed secondary battery having a current interrupt mechanism with a high heat resistance that prevents fusion of the current collecting plate by the Joule heat generated during high-rate charge and discharged. A current interrupt mechanism 80 of a sealed secondary battery 10 provided in accordance with the present invention is configured such that when the internal pressure inside a battery case 12 rises above the predetermined level, a current interrupt valve 30 is deformed by the internal pressure in a direction of separating from a rectangular plate-shaped current collecting plate 72 and the current collecting plate breaks in the portion of an annular groove 79 of a central thin section 74 of the current collecting plate.
