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 for 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 inward 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 parts thereof. The valve body has an annular thin-wall part capable of deforming when the internal pressure in the battery rises. The thin-wall part forms a recess on the insulating member side of the valve body. The insulating member has a portion P1 covering the valve body-side surface of the metal plate. The portion P1 has a rib housed in the recess.
(FR) L’invention concerne une batterie cylindrique qui comporte : un groupe d’électrodes ; un électrolyte ; un boîtier de batterie destiné à loger le groupe d’électrodes et l’électrolyte ; et un corps étanche destiné à sceller une ouverture du boîtier de batterie. Le corps étanche comporte un corps de soupape, une plaque de métal disposée plus loin à l’intérieur de la batterie que le corps de soupape, et un organe isolant annulaire intercalé entre le corps de soupape et la plaque de métal. Le corps de soupape et la plaque de métal sont connectés entre eux par leurs parties centrales respectives. Le corps de soupape a une partie annulaire à paroi mince pouvant se déformer lorsque la pression interne dans la batterie augmente. La partie à paroi mince forme un évidement du côté de l’organe isolant du corps de soupape. L’organe isolant a une partie (P1) recouvrant la surface du côté du corps de soupape de la plaque de métal. La partie (P1) a une nervure logée dans l’évidement.
(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し、肉薄部により弁体の絶縁部材側に凹部が形成されている。絶縁部材は、金属板の弁体側の表面を覆う部位P1を有し、部位P1は、凹部内に収容されるリブを有する。
