Abstract

Una batería secundaria cilíndrica (100) que incluye un conjunto (400) de caperuza construido con una estructura en la que un conducto (420), el cual intercepta la corriente eléctrica y descarga el gas a presión cuando aumenta la presión interior de la batería debido al funcionamiento anormal de la batería, está en contacto con una caperuza superior (410) que tiene una parte central que sobresale, en donde el extremo del conducto (420) está curvado para rodear la superficie circunferencial exterior (414) de la caperuza superior (410), y una acanaladura (416) para impedir la fuga de un electrolito e impedir la ocurrencia de defectos en la batería durante el montaje de la batería está formada en las interfaces entre el conducto (420) y la caperuza superior (410) de modo que la acanaladura (416) está de forma continua dispuesta en paralelo con la superficie circunferencial exterior (414) de la caperuza superior (410).
