Title (EN) SECONDARY BATTERY HAVING CATHODE TERMINAL-INTEGRATED CAP PLATE
(FR) BATTERIE SECONDAIRE AYANT UNE PLAQUE DE CAPUCHON INTÉGRÉE À UNE BORNE DE CATHODE
(KO) 양극 단자 일체형 캡 플레이트를 갖는 이차 전지
Abstract:
(EN) Various embodiments of the present invention relate to a secondary battery, and the technical problem to be solved is to provide a secondary battery having a cathode terminal-integrated cap plate, which prevents the occurrence of weld defects during welding of a bus bar. To this end, the present invention provides a secondary battery comprising: a case; an electrode assembly received in the case; and a cap plate coupled to the case so as to protect the electrode assembly, wherein the cap plate includes a terminal part to which the electrode assembly is electrically connected and which is formed integrally with the cap plate, and the terminal part is thicker than the cap plate.
(FR) Divers modes de réalisation de la présente invention concernent une batterie secondaire, et le problème technique à résoudre est de fournir une batterie secondaire ayant une plaque de capuchon intégrée à une borne de cathode, qui empêche l'apparition de défauts de soudure pendant le soudage d'une barre omnibus. A cet effet, la présente invention concerne une batterie secondaire comprenant : un boîtier; un ensemble d'électrodes reçu dans le boîtier; et une plaque de capuchon couplée au boîtier de façon à protéger l'ensemble d'électrodes, la plaque de capuchon comprenant une partie de borne à laquelle l'ensemble d'électrode est électroconnecté et qui est formée d'un seul tenant avec la plaque de capuchon, et la partie de borne est plus épaisse que la plaque de capuchon.
(KO) 본 발명의 다양한 실시예는 이차 전지에 관한 것으로, 해결하고자 하는 기술적 과제는 버스바의 용접 시 용접 불량이 발생하지 않는 양극 단자 일체형 캡 플레이트를 갖는 이차 전지를 제공하는데 있다. 이를 위해 본 발명은 케이스; 상기 케이스의 내측에 수용된 전극 조립체; 및 상기 케이스에 결합되어 상기 전극 조립체를 보호하는 캡 플레이트를 포함하고, 상기 캡 플레이트는 상기 전극 조립체가 전기적으로 연결되며 상기 캡 플레이트와 일체로 형성된 단자부를 포함하고, 상기 단자부의 두께는 상기 캡 플레이트의 두께보다 두꺼운 이차 전지를 개시한다.
