Title (EN) SEALING APPARATUS FOR SECONDARY BATTERY
(FR) APPAREIL D'ÉTANCHÉIFICATION DE BATTERIE SECONDAIRE
(KO) 이차전지용 실링장치
Abstract:
(EN) The present invention relates to a sealing apparatus for a secondary battery that seals a sealing part of a case in which an electrode assembly and an electrolyte are accommodated and that includes a sealing member provided with a first sealing piece and a second sealing piece for sealing by heat-welding a surface of the sealing part, wherein the first sealing piece and the second sealing piece are arranged from an external-side end of the surface of the sealing part towards a direction of an internal-side end that is an opposite direction to the outer end, and have a plurality of heat-welding parts that seal by heat-welding a surface of the sealing part, and non-heat-welding parts that are arranged between the plurality of heat-welding parts and that do not seal the surface of the sealing part.
(FR) La présente invention concerne un appareil d'étanchéification de batterie secondaire qui permet de sceller une partie d'étanchéité d'un boîtier dans lequel un ensemble d'électrode et un électrolyte sont logés, ledit appareil incluant un élément d'étanchéité doté d'une première pièce d'étanchéité et d'une seconde pièce d'étanchéité destinées à l'étanchéification par thermosoudage d'une surface de la partie d'étanchéité, la première pièce d'étanchéité et la seconde pièce d'étanchéité étant disposées depuis une extrémité de côté externe de la surface de la partie d'étanchéité en direction d'une extrémité de côté interne (qui est une direction opposée à l'extrémité externe) et ayant une pluralité de parties de thermosoudage qui scellent par thermosoudage une surface de la partie d'étanchéité, ainsi que des parties non thermosoudées étant disposées entre la pluralité de parties de thermosoudage et ne participant pas à l'étanchéification de la surface de la partie d'étanchéité.
(KO) 본 발명에 따른 전극조립체와 전해액이 수용된 케이스의 실링부를 실링하는 이차전지용 실링장치에 관한 것으로, 실링부의 표면을 열융착하여 실링하는 제1 실링편과 제2 실링편으로 마련된 실링부재를 포함하며, 상기 제1 실링편과 상기 제2 실링편은 상기 실링부 표면의 외측 끝단에서 반대쪽인 내측 끝단방향으로 구비되고 상기 실링부의 표면을 열융착하여 실링하는 복수개의 열융착부와, 상기 복수개의 열융착부 사이에 구비되고 상기 실링부의 표면을 실링하지 않는 미열융착부로 마련된다.
