Title (EN) CYLINDRICAL BATTERY
(FR) BATTERIE CYLINDRIQUE
(JA) 円筒形電池
Abstract:
(EN) A cylindrical battery provided with: an electrode group; an electrolyte; a battery can housing the electrode group and the electrolyte; and a sealing body for sealing an opening of the battery can. The sealing body is provided with a valve body, a metal plate disposed farther towards the inside of the battery than the valve body, and an annular insulating member interposed between the valve body and the metal plate. The valve body and the metal plate are connected to each other at the respective center sections. The valve body has an annular thin-walled part capable of deforming when the internal pressure of the battery rises. The metal plate and the insulating member have holes that communicate with each other. The insulating member has a portion P1 covering the valve body-side surface of the metal plate, and a portion P2 which is provided in continuation from the portion P1 and which covers the side surface of the hole in the metal plate.
(FR) L'invention concerne une batterie cylindrique comprenant : un groupe d'électrodes; un électrolyte; un boîtier de batterie logeant le groupe d'électrodes et l'électrolyte; et un corps d'étanchéité pour étanchéifier une ouverture du boitier de batterie. Le corps d'étanchéité comprend un corps de soupape, une plaque métallique disposée plus loin vers l'intérieur de la batterie que du corps de soupape, et un élément isolant annulaire interposé entre le corps de soupape et la plaque métallique. Le corps de soupape et la plaque métallique sont reliés l'un à l'autre au niveau des sections centrales respectives. Le corps de soupape comporte une partie annulaire à paroi mince apte à se déformer lorsque la pression interne de la batterie s'élève. La plaque métallique et l'élément isolant ont des trous qui communiquent l'un avec l'autre. L'élément isolant a une partie P1 recouvrant la surface côté corps de soupape de la plaque métallique, et une partie P2 qui est disposée dans la continuation de la partie P1 et qui recouvre la surface latérale du trou dans la plaque métallique.
(JA) 円筒形電池は、電極群と、電解質と、電極群と電解質とを収容する電池缶と、電池缶の開口を封口する封口体と、を備える。封口体は、弁体と、弁体よりも電池の内方側に配置される金属板と、弁体と金属板との間に介在する環状の絶縁部材と、を備える。弁体および金属板は、それぞれの中央部において、互いに接続されている。弁体は、電池の内圧上昇時に変形可能な環状の肉薄部を有する。金属板および前記絶縁部材は、それぞれ、互いに連通する孔を有する。絶縁部材は、金属板の弁体側の表面を覆う部位P1と、部位P1に続いて設けられるとともに金属板の孔の側面を覆う部位P2と、を有する。
