Abstract: front page image
(EN)Disclosed is a sealed battery in which a case (20) is partially provided with a safety valve (40) that is provided with a thin portion (42), which is formed thinner than the peripheral portion of the safety valve. A portion of the safety valve surrounding the thin portion is provided with a slit (80) for preventing heat conduction from the other portions of the case to the thin portion, said slit (80) being formed so as to surround the thin portion.
(FR)L'invention porte sur une batterie scellée dans laquelle un boîtier (20) est partiellement muni d'une soupape de sûreté (40) qui comprend une partie mince (42), qui est formée plus mince que la partie périphérique de la soupape de sûreté. Une partie de la soupape de sûreté entourant la partie mince comprend une fente (80) pour empêcher une conduction de chaleur des autres parties du boîtier à la partie mince, ladite fente (80) étant formée de façon à entourer la partie mince.
