Title (EN) CABLE-TYPE SECONDARY BATTERY HAVING A POLYMER CURRENT COLLECTOR COATED WITH METAL
(FR) BATTERIE SECONDAIRE DE TYPE CÂBLE COMPRENANT UN COLLECTEUR DE COURANT POLYMÈRE RECOUVERT DE MÉTAL
(KO) 금속 코팅된 고분자 집전체를 갖는 케이블형 이차전지
Abstract: front page image
(EN)The present invention relates to a cable-type secondary battery comprising: a current collector having a horizontal cross-sectional surface of a predetermined shape; and electrodes, each of which includes an active material layer formed on the surface of the current collector, and each of which extends in a lengthwise direction, wherein the electrodes are arranged in parallel. The current collector includes: a polymer core portion; and a metal coating layer formed on the surface of the polymer core portion. The above-described cable-type secondary battery uses the polymer current collector which is coated with metal and which is both highly flexible and highly conductive, thus maintaining battery performance and superior flexibility. In addition, the secondary battery of the present invention is lightweight.
(FR)L'invention concerne une batterie secondaire de type câble comprenant : un collecteur de courant dont la section transversale possède une surface horizontale ayant une forme prédéterminée ; et des électrodes comprenant chacune une couche d'un matériau actif formée sur la surface du collecteur de courant et s'étendant chacune dans le sens de la longueur, lesquelles électrodes sont parallèles. Le collecteur de courant comprend : une partie noyau polymère ; et une couche de revêtement métallique formée sur la surface de la partie noyau polymère. Cette batterie secondaire de type câble utilise le collecteur de courant polymère qui est recouvert de métal et qui est à la fois grandement flexible et hautement conducteur, ce qui permet de préserver les performances de la batterie ainsi qu'une flexibilité supérieure. En outre, la batterie secondaire de la présente invention a un faible poids.
(KO)본 발명은 소정 형상의 수평 단면을 가지는 집전체 및 상기 집전체의 표면에 형성된 활물질층을 포함하고, 길이 방향으로 연장되며 평행하게 배치되는 전극을 구비하는 케이블형 이차전지에 있어서, 상기 집전체는 고분자 코어부 및 상기 고분자 코어부 표면에 형성된 금속 코팅층을 포함하는 것을 특징으로 하는 케이블형 이차전지에 대한 것이다. 이러한 케이블형 이차전지는 높은 가요성 및 전도성을 동시에 갖는 금속 코팅된 고분자 집전체를 사용하여, 전지성능을 유지하면서 우수한 가요성을 갖는다. 또한 경량화가 가능하다.
