Abstract
(EN) The present invention relates to a secondary battery in which an insulation sheet is inserted between a cap-up and a case, thereby increasing safety. Disclosed according to an embodiment is a secondary battery comprising: an electrode assembly; a case for receiving the electrode assembly; a cap assembly coupled to an upper part of the case; and a gasket interposed between the cap assembly and the case, wherein the cap assembly comprises: a cap-up; a safety belt installed at a lower part of the cap-up and extending to an upper part of the cap-up so as to surround a periphery of the cap-up; and an insulation sheet positioned at an upper part of the safety belt extending to the upper part of the cap-up.
(FR) La présente invention concerne une batterie secondaire dans laquelle une feuille d'isolation est introduite entre un capuchon et un boîtier, ce qui permet d'augmenter la sécurité. Selon un mode de réalisation, l'invention concerne une batterie secondaire comprenant : un ensemble électrode ; un boîtier permettant de recevoir l'ensemble électrode ; un ensemble capuchon couplé à une partie supérieure du boîtier ; et un joint d'étanchéité intercalé entre l'ensemble capuchon et le boîtier, l'ensemble capuchon comprenant : un capuchon ; une ceinture de sécurité installée au niveau d'une partie inférieure du capuchon et s'étendant jusqu'à une partie supérieure du capuchon de manière à entourer une périphérie du capuchon ; et une feuille d'isolation positionnée au niveau d'une partie supérieure de la ceinture de sécurité s'étendant jusqu'à la partie supérieure du capuchon.
