Title (EN) CABLE-TYPE SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE DU TYPE À CÂBLE
(KO) 케이블형 이차전지
Abstract: front page image
(EN)The cable-type secondary battery of the present invention comprises: an inner electrode including a thin and long first polar current collector having a cross section in the shape of a circle, an oval, or a polygon when crossing at a right angle therewith in the direction of the length thereof, a first polar electrode active material layer formed on the outer surface of the first polar current collector, and a first polar electrode having an electrolyte layer filled so as to surround the first polar electrode active material layer; and one or more wire-type second polar electrodes, enshrouding the whole inner electrode, and wound on the outer surface thereof. The cable-type secondary battery having the wound outer electrode of the present invention has an excellent fusibility and prevents the abscission of the active material.
(FR)La présente invention concerne une batterie secondaire du type à câble qui comprend : une électrode interne comprenant un premier collecteur de courant polaire mince et long dont la coupe transversale a la forme d'un cercle, d'un ovale ou d'un polygone lors d'une coupe à angle droit avec celui-ci dans le sens de sa longueur, une première couche de matériau actif d'électrode polaire formée sur la surface externe du premier collecteur de courant polaire, et une première électrode polaire possédant une couche d'électrolyte remplie de façon à entourer la première couche de matériau actif d'électrode polaire ; et une ou plusieurs secondes électrodes du type à câble, enveloppant l'intégralité de l'électrode interne, et enroulées sur sa surface externe. La batterie secondaire du type à câble de l'invention possédant l'électrode externe enroulée présente une excellente aptitude à la fusion et évite l'abscission du matériau actif.
(KO)본 발명의 케이블형 이차전지는, 그 길이 방향에 직교하는 단면이 원형, 타원형 또는 다각형 형태의 가늘고 긴 제1 극성 집전체, 상기 제1 극성 집전체의 외면에 형성된 제1 극성 전극 활물질층, 및 상기 제1 극성 전극 활물질층을 둘러싸도록 충진된 전해질층을 구비하는 제1 극성 전극을 하나 이상 포함하는 내부전극; 및 상기 내부전극 전체를 감싸며 그 외면에 권선되는 하나 이상의 와이어형 제2 극성 전극을 구비한다. 와인딩된 외부전극을 구비하는 케이블형 이차전지인 본 발명은 가요성이 우수하고, 활물질의 탈리를 예방할 수 있다.
