Title (EN) SECONDARY BATTERY WITH ENHANCED SEALING PERFORMANCE
(FR) ACCUMULATEUR SECONDAIRE À PERFORMANCES D'ÉTANCHÉITÉ SUPÉRIEURES
(KO) 밀봉성이 향상된 이차전지
Abstract: front page image
(EN)The present invention relates to a secondary battery provided with an electrode assembly, which is embedded in an angular can, wherein the electrolyte injection port of a base plate, which is mounted on the open top of the angular can, comprises an upper portion having a chamfer structure with the diameter of the inner surface decreasing in the bottom direction, and a lower portion having a non-chamfer structure, wherein the chamfer structure comprises an uneven form so as to increase the path for leaking the electrolyte from the inside to the outside of the secondary battery. The present invention provides the secondary battery in which, when a sealing member is press-fitted into the electrolyte injection port, the sealing member is modified according to the inner surface structure of the electrolyte injection port to perform sealing.
(FR)La présente invention concerne un accumulateur secondaire comprenant un ensemble d'électrodes qui est logé dans un boîtier angulaire. L'orifice d'injection d'électrolyte d'une plaque de base, qui est montée sur la partie supérieure ouverte du boîtier angulaire, comprend une partie supérieure ayant une structure chanfreinée dont le diamètre de la surface intérieure diminue dans la direction du bas et une partie inférieure dotée d'une structure non chanfreinée. La structure chanfreinée comprend une forme irrégulière afin d'augmenter la section de fuite de l'électrolyte entre l'intérieur et l'extérieur de l'accumulateur secondaire. La présente invention concerne un accumulateur secondaire dans lequel, lorsqu'un élément d'étanchéité est monté à force dans l'orifice d'injection d'électrolyte, l'élément d'étanchéité est modifié en fonction de la structure de la surface intérieure de l'orifice d'injection d'électrolyte afin de réaliser l'étanchéité.
(KO)본 발명은 전극조립체가 각형 캔에 내장되어 있는 이차전지로서, 상기 각형 캔의 개방 상단에 장착되는 베이스 플레이트의 전해액 주입구의 내면은 상부가 하부 방향으로 직경이 작아지는 챔퍼 구조로 형성되어 있고, 하부가 비챔퍼 구조로 형성되어 있으며, 상기 챔퍼 구조는 이차전지 내부에서 외부로의 전해액 누액 경로를 증가시키기 위해 요철 형상으로 이루어져 있고, 상기 전해액 주입구에 밀봉부재를 압입할 때 상기 전해액 주입구의 내면 구조에 대응하여 밀봉부재가 변형되면서 밀봉이 이루어지는 이차전지를 제공한다.
