Title (EN) POUCH-TYPE SECONDARY BATTERY COMPRISING ELECTRODE TAB CUTTING DEVICE
(FR) BATTERIE SECONDAIRE DE TYPE POCHE COMPRENANT UN DISPOSITIF DE DÉCOUPAGE DE LANGUETTE D'ÉLECTRODE
(KO) 전극 탭 절단 장치를 포함하는 파우치형 이차전지
Abstract:
(EN) The present invention relates to a pouch-type secondary battery comprising an electrode tab cutting device, wherein an electrode assembly of a structure, in which a positive electrode, a separation film, and a negative electrode are laminated, is housed within a pouch case, wherein an electrode tab or an electrode lead within the pouch case of the electrode assembly is cut by means of an elastic member which is positioned within the pouch case and is triggered by an increase in the internal pressure of the pouch.
(FR) La présente invention concerne une batterie secondaire de type poche comprenant un dispositif de découpage de languette d'électrode, un ensemble d'électrodes d'une structure, dans lequel une électrode positive, un film de séparation et une électrode négative étant stratifiés, est logé à l'intérieur d'un boîtier de poche, une languette d'électrode ou un fil d'électrode à l'intérieur du boîtier de poche de l'ensemble d'électrodes étant découpé au moyen d'un élément élastique qui est positionné à l'intérieur du boîtier de poche et est déclenché par une augmentation de la pression interne de la poche.
(KO) 본 발명은 양극, 분리막 및 음극이 적층된 구조의 전극조립체를 파우치 케이스 내에 수용하는 파우치형 이차전지에 있어서, 상기 파우치 케이스 내에 위치하며 상기 파우치의 내압 증가에 의해 트리거링 되는 탄성 부재에 의하여 상기 전극조립체의 상기 파우치 케이스 내의 전극 탭 또는 전극리드를 절단하는 전극 탭 절단 장치를 포함하는 파우치형 이차전지에 대한 것이다.
