Title (EN) CABLE-TYPE SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE À CÂBLE
(KO) 케이블형 이차전지
Abstract: front page image
(EN)The present invention relates to a cable-type secondary battery comprising: a lithium-ion supply core portion; an inner electrode comprising an inner current collector that encases the outer surface of the lithium-ion supply core portion and has an open structure, an active material layer that is formed on the surface of the inner current collector, and an electrolyte absorbing layer that is formed on the outer surface of the active material layer; a separation layer, which is formed so as to encase the outer surface of the inner electrode, for preventing a short circuit of an electrode; and an outer electrode that encases the outer surface of the separation layer, and is provided with an outer electrode active material layer and an outer current collector, wherein the cable-type secondary battery has a horizontal cross-section that has a specific shape and is extended in the lengthwise direction. The lithium-ion supply core portion comprising the electrolyte, according to the present invention, is positioned inside the inner electrode, which has an open structure, wherein the electrolyte in the lithium-ion supply core portion can easily penetrate into the active material of the electrode, thereby facilitating supply and exchange of lithium-ion. Also, the inner electrode, according to the present invention, is provided with the electrolyte absorbing layer on the outer surface thereof, which allows containing the electrolyte in the lithium-ion supply core portion inside the inner electrode, thereby facilitating supply and exchange of lithium-ion.
(FR)La présente invention concerne une batterie secondaire à câble comprenant: une partie centrale d'alimentation en lithium-ion; une électrode intérieure comprenant un appareil de prise de courant interne qui revêt la surface extérieure de la partie centrale d'alimentation en lithium-ion et présente une structure ouverte, une couche d'une matière active qui est formée sur la surface de l'appareil de prise de courant interne; et une couche d'absorption de l'électrolyte qui est formée sur la surface extérieure de la couche de matière active; une couche de séparation qui est formée de manière à revêtir la surface extérieure d'une électrode intérieure pour empêcher un court-circuit d'une électrode; et une électrode extérieure qui revêt la surface extérieure de la couche de séparation, et qui est pourvue d'une couche d'une matière active d'électrode extérieure et d'un appareil de prise de courant; la batterie secondaire à câble présente une section transversale horizontale ayant une forme spécifique et s'étendant dans le sens de la longueur. La partie centrale d'alimentation en lithium-ion comprenant l'électrolyte, selon la présente invention, est disposée à l'intérieur de l'électrode intérieure, laquelle présente une structure ouverte. L'électrolyte dans la partie centrale d'alimentation en lithium-ion peut pénétrer facilement dans la matière active de l'électrode, ce qui permet de faciliter l'alimentation et l'échange de lithium-ion. En outre, l'électrode intérieure selon l'invention est pourvue d'une couche d'absorption d'électrolyte sur sa surface extérieure, ce qui permet de contenant l'électrolyte dans la partie centrale d'alimentation en lithium-ion à l'intérieur de l'électrode intérieure, facilitant ainsi l'alimentation et l'échange de lithium-ion.
(KO)본 발명은 전해질을 포함하는 리튬이온 공급 코어부; 상기 리튬이온 공급 코어부의 외면을 둘러싸며 형성된 열린 구조의 내부집전체, 상기 내부집전체의 표면에 형성된 내부전극 활물질층과 상기 내부전극 활물질층의 외면에 형성된 전해질 흡수층을 구비하는 내부전극; 상기 내부전극의 외면을 둘러싸며 형성된 전극의 단락을 방지하는 분리층; 및 상기 분리층의 외면을 둘러싸며 형성되고, 외부전극 활물질층과 외부집전체를 구비하는 외부전극;을 포함하는 소정 형상의 수평 단면을 가지고 길이 방향으로 연장된 케이블형 이차전지에 관한 것이다. 본 발명의 전해질을 포함하는 리튬이온 공급 코어부는 내부전극의 내부에 위치하고 있으며 상기 내부전극은 열린 구조를 가지므로, 이러한 리튬이온 공급 코어부의 전해질은 전극의 활물질으로의 침투가 용이하여, 리튬이온의 공급 및 리튬이온의 교환을 용이하게 할 수 있다. 또한, 본 발명의 내부전극은 외면에 전해질 흡수층을 구비하므로 리튬이온 공급 코어부의 전해질을 내부전극의 내부에 함유할 수 있으므로, 리튬이온의 공급 및 리튬이온의 교환을 돕는다.
