Title (EN) CABLE-TYPE SECONDARY BATTERY 케이블형 이차전지
(FR) ACCUMULATEUR DE TYPE CÂBLE
(KO) 케이블형 이차전지
Abstract: front page image
(EN)The present invention relates to a cable-type secondary battery, comprising: an electrode assembly further including a first polar electrode and a second polar electrode, each of the electrodes which are formed in a thin and long shape on the surface of a current collector having a cross section that creates a right angle with the lengthwise direction thereof in the shape of a circle, an asymmetric ellipse, or a polygon, the surface of the electrode being coated with an electrode active material, and including electrolyte or a dividing film that is interposed between the first power electrode and the second polar electrode; and a cover member for covering the electrode assembly, wherein the cover member is provided with an uneven pattern of a predetermined form that is at least partially concave or protruding in the direction of the electrode assembly. The present invention is highly flexible as the cover member is provided with the uneven pattern having an uneven structure. Also, when the cover member having the uneven structure is applied to the cable-type secondary battery, which is provided with an active material layer that forms the pattern, flexibility can be maximized.
(FR)La présente invention concerne un accumulateur de type câble comprenant : un ensemble électrode constitué en outre d'une première et d'une deuxième électrode polaire, chacune des électrodes ayant une forme mince et allongée sur la surface d'un collecteur de courant dont la section transversale forme un angle droit avec le sens longitudinal de celui-ci sous la forme d'un cercle, d'une ellipse asymétrique ou d'un polygone, la surface de l'électrode étant recouverte d'un matériau actif et comprenant un électrolyte ou un film de séparation qui est placé entre la première et la deuxième électrode polaire; et un élément de recouvrement permettant de recouvrir l'ensemble électrode, l'élément de recouvrement étant pourvu d'un motif irrégulier d'une forme prédéterminée qui est au moins partiellement concave ou fait saillie dans le sens de l'ensemble électrode. La présente invention est extrêmement flexible du fait que l'élément de recouvrement est pourvu du motif irrégulier présentant une structure irrégulière. En outre, lorsque l'élément de recouvrement présentant la structure irrégulière est appliqué sur l'accumulateur de type câble, qui est pourvu d'une couche de matériau actif formant le motif, sa flexibilité peut être accrue.
(KO)본 발명은 그 길이 방향에 직교하는 단면이 원형, 비대칭형 타원 또는 다각형 형태의 집전체 표면에 전극 활물질이 도포된 가늘고 길게 각각 구성된 제1 극성 전극과 제2 극성 전극, 및 상기 제1 극성 전극과 상기 제2 극성 전극 사이에 개재된 분리막 또는 전해질을 포함하는 전극 조립체; 및 상기 전극 조립체를 감쌀 수 있는 커버부재를 구비하는 케이블형 이차전지에 있어서, 상기 커버부재는 상기 전극 조립체 방향으로 적어도 부분적으로 인입 또는 돌출된 미리 결정된 형태의 요철 패턴을 구비하는 것을 특징으로 하는 케이블형 이차전지에 관한 것이다. 본 발명은, 커버부재가 요철구조를 가지는 요철 패턴을 구비하므로 가요성이 우수하다. 또한, 패턴을 형성하는 활물질층을 구비하는 케이블형 이차전지에 요철구조의 커버부재를 적용하는 경우에는 가요성을 극대화할 수 있다.
