Title (EN) SECONDARY BATTERY
(FR) BATTERIE RECHARGEABLE
(JA) 二次電池
Abstract:
(EN) The present invention is a secondary battery that is provided with: an electrode body including a positive electrode plate and a negative electrode plate; an exterior body that has an opening and that accommodates the electrode body; and a sealing plate (2) for sealing the opening in the exterior body, wherein the exterior body and the sealing plate (2) constitute a battery case. The sealing plate (2) is provided with: a deforming section (19) that deforms when the pressure in the battery case is equal to or more than a prescribed value; and a gas discharge valve (18) that fractures and discharges a gas in the battery case to the outside of the battery case when the pressure in the battery case is equal to or more than the prescribed value. A metal reinforcing member (30) is joined to an internal surface of the sealing plate (2).
(FR) La présente invention concerne une batterie rechargeable qui comporte : un corps d'électrode comprenant une plaque d'électrode positive et une plaque d'électrode négative ; un corps extérieur qui comporte une ouverture et qui reçoit le corps d'électrode ; et une plaque d'étanchéité (2) destinée à sceller l'ouverture dans le corps extérieur, le corps extérieur et la plaque d'étanchéité (2) constituant un boîtier de batterie. La plaque d'étanchéité (2) comporte : une section de déformation (19) qui se déforme lorsque la pression dans le boîtier de batterie est égale ou supérieure à une valeur prescrite ; et une soupape d'évacuation de gaz (18) qui fracture et évacue un gaz dans le boîtier de batterie vers l'extérieur du boîtier de batterie lorsque la pression dans le boîtier de batterie est égale ou supérieure à la valeur prescrite. Un élément de renforcement métallique (30) est relié à une surface interne de la plaque d'étanchéité (2).
(JA) 正極板と負極板を含む電極体と、開口を有し電極体を収納する外装体と、外装体の開口を封口する封口板(2)を備え、外装体と封口板(2)が電池ケースを構成する二次電池であって、封口板(2)には、電池ケース内の圧力が所定値以上となった時に変形する変形部(19)と、電池ケース内の圧力が所定値以上となった時に破断し電池ケース内のガスを電池ケースの外部に排出するガス排出弁(18)が設けられており、封口板(2)の内面には金属製の補強部材(30)が接続されている二次電池。
