Abstract: front page image
(EN)The secondary battery according to the present invention comprises: an electrode assembly including an electrode tab; an electrode lead attached to the electrode tab and including at least one lead hole; a pouch case accommodating the electrode assembly in such a manner that the electrode lead is withdrawn to the outside; and a venting pattern portion formed in an area corresponding to the lead hole, and sealing tape provided in such a manner as to be interposed between the electrode lead and the inner surface of the pouch case. According to the present invention, the sealing state of the pouch case is swiftly released in the event that gas is generated in the pouch case due to an abnormality such as excess current flowing through the secondary battery caused by abnormal operation of a protective circuit, and thus the secondary battery can be used safely.
(FR)La batterie secondaire selon la présente invention comprend : un ensemble électrode comprenant une languette d'électrode ; un conducteur d'électrode fixé à la languette d'électrode et comprenant au moins un trou de conducteur ; un boîtier en forme de poche recevant l'ensemble électrode d'une manière telle que le conducteur d'électrode est retiré vers l'extérieur ; et une partie de motif d'aération formée dans une zone correspondant au trou de conducteur, et une bande d'étanchéité disposée de manière à être interposée entre le conducteur d'électrode et la surface interne du boîtier en forme de poche. Selon la présente invention, l'état d'étanchéité du boîtier en forme de poche est libéré de manière rapide dans le cas où du gaz est généré dans le boîtier en forme de poche en raison d'une anomalie, telle qu'un courant en excès circulant à travers la batterie secondaire provoqué par un fonctionnement anormal d'un circuit de protection, et la batterie secondaire peut être ainsi utilisée de manière sécurisée.
(KO)본 발명에 따른 이차전지는, 전극 탭을 구비하는 전극 조립체; 상기 전극 탭에 부착되며 적어도 하나의 리드 홀을 구비하는 전극 리드; 상기 전극 리드가 외부로 인출되도록 상기 전극 조립체를 수용하는 파우치 케이스; 및 상기 리드 홀과 대응되는 영역에 형성되는 벤팅 패턴부를 구비하는 것으로서 상기 전극 리드 및 상기 파우치 케이스의 내측 면 사이에 개재되는 실링 테이프를 포함한다. 본 발명에 따르면, 보호회로가 정상 작동하지 않아 이차전지에 과전류가 흐르는 등의 이상 현상 발생으로 인해 파우치 케이스 내부에 가스가 생성되는 경우 파우치 케이스의 밀봉 상태가 신속히 해제됨으로써 이차전지 사용상의 안전성을 확보할 수 있다.
