Abstract: front page image
(EN) According to one embodiment of the present invention, a rechargeable battery comprises: an electrode assembly formed by winding a first electrode, a separator, and a second electrode; and a pouch having a sealing portion formed by thermally bonding the outer peripheries of a first external material and a second external material, which have the electrode assembly accommodated therein, so as to withdraw, to the outside, tabs respectively connected to the first electrode and the second electrode, wherein the electrode assembly has first curved portions convex on both sides of a first plane portion in a winding cross section, the pouch has a second plane portion corresponding to the first plane portion and a second curved portion connected to the second plane portion by corresponding to the first curved portions, and the sealing portion is located within a space set by: an extending plane set in an extending direction of the first plane portion; an outer surface of the second curved portion protruding in the extending direction; and a crossing plane set in a direction that crosses the extending direction at the end of the extending direction of the second curved portion.
(FR) Selon un mode de réalisation de la présente invention, une batterie rechargeable comprend : un assemblage d'électrodes formé par enroulement d'une première électrode, un séparateur, et une seconde électrode; et une poche ayant une portion d'étanchéité formée par liaison thermique des périphéries externes d'un premier matériau externe et d'un second matériau externe, dans laquelle est logé l'assemblage d'électrodes, de manière à retirer, à l'extérieur, des languettes respectivement reliées à la première électrode et à la seconde électrode, l'assemblage d'électrodes ayant des premières portions incurvées convexes sur les deux côtés d'une première portion plane dans une section transversale d'enroulement, la poche a une seconde portion plane correspondant à la première portion plane et une seconde partie incurvée reliée à la seconde portion plane par correspondance avec les premières portions incurvées, et la portions d'étanchéité est située à l'intérieur d'un espace défini par: un plan d'extension défini dans une direction d'extension de la première portion plane; une surface externe de la seconde portion incurvée faisant saillie dans la direction d'extension; et un plan de croisement réglé dans une direction qui croise la direction d'extension à l'extrémité de la direction d'extension de la seconde portion incurvée.
(KO) 본 발명의 일 실시예에 따른 이차 전지는, 제1전극, 세퍼레이터 및 제2전극을 권취하여 형성되는 전극 조립체, 및 상기 제1전극과 상기 제2전극에 각각 연결되는 탭을 외부로 인출하도록 상기 전극 조립체를 수용하는 제1외장재와 제2외장재의 외곽을 열융착하여 실링부를 형성되는 파우치를 포함하며, 상기 전극 조립체는, 권취 단면에서 제1평면부의 양측에 볼록한 제1곡면부를 구비하고, 상기 파우치는, 상기 제1평면부에 대응하는 제2평면부와 상기 제1곡면부에 대응하여 상기 제2평면부에 연결되는 제2곡면부를 구비하며, 상기 실링부는, 상기 제1평면부의 연장 방향으로 설정되는 연장 평면, 상기 연장 방향으로 돌출되는 상기 제2곡면부의 외면, 및 상기 제2곡면부의 상기 연장 방향 끝에서 상기 연장 방향에 교차하는 방향으로 설정되는 교차 평면으로 설정되는 공간 내에 위치한다.
