Abstract

La présente invention concerne une structure de fixation d'une borne d'électrode, ainsi qu'une batterie, une batterie à plusieurs éléments et un véhicule comprenant celle-ci. La structure de fixation d'une borne d'électrode peut comprendre : un boîtier de batterie dont un côté est ouvert et l'autre côté comporte un fond présentant un trou traversant formé dans ce fond ; une borne d'électrode installée à travers le trou traversant sans entrer en contact avec la paroi interne du trou traversant ; et un joint d'étanchéité de borne interposé entre la borne d'électrode et le trou traversant, une couche thermofusible pouvant être interposée au niveau de l'interface entre la borne d'électrode et le joint d'étanchéité de borne ou au niveau de l'interface entre le joint d'étanchéité de borne et le boîtier de batterie.The present invention relates to a structure for securing an electrode terminal, as well as a battery, a multi-cell battery, and a vehicle comprising the battery. The structure for securing an electrode terminal may comprise: a battery case, one side of which is open and the other side of which has a base with a through hole formed in that base; an electrode terminal installed through the through hole without contacting the inner wall of the through hole; and a terminal seal interposed between the electrode terminal and the through hole, a heat-fusible layer being interposed at the interface between the electrode terminal and the terminal seal or at the interface between the terminal seal and the battery case.
