Abstract: front page image
(EN)The present invention provides an integrated electrode assembly wherein: a positive electrode, a negative electrode, and a separating layer located between the positive electrode and negative electrode have a mutually integrated structure; the separating layer is formed of three phases of a liquid component including ionic salt, a solid component which supports the separating layer between the positive electrode and negative electrode, and a polymer matrix which includes linear polymers and crosslinking polymers forming a viscoelastic structure while containing the liquid component and solid component therein; the polymer matrix is coupled with the positive electrode and negative electrode, respectively; and, in the manufacture of the electrode assembly, the liquid component of the separating layer flows into the electrode, so that the wetting characteristic of the electrode is significantly improved, and ion conductivity is also improved.
(FR)La présente invention concerne un ensemble d'électrodes intégré, une électrode positive, une électrode négative, et une couche de séparation située entre l'électrode positive et l'électrode négative ayant une structure mutuellement intégrée ; la couche de séparation étant formée de trois phases d'un composant liquide comprenant un sel ionique, un composant solide qui supporte la couche de séparation entre l'électrode positive et l'électrode négative, et une matrice polymère qui comprend des polymères linéaires et des polymères de réticulation formant une structure viscoélastique tout en contenant à l'intérieur le composant liquide et le composant solide ; la matrice polymère étant couplée à l'électrode positive et à l'électrode négative, respectivement ; et, dans la fabrication de l'ensemble d'électrodes, le composant liquide de la couche de séparation circule dans l'électrode, de sorte que la caractéristique de mouillage de l'électrode est sensiblement améliorée, de même que la conductivité ionique.
(KO)본 발명은 양극, 음극, 및 상기 양극과 음극 사이에 위치하는 분리층이 상호 일체형 구조를 가지고, 상기 분리층은 이온성 염을 포함하는 액상 성분과, 양극과 음극 사이에서 분리층을 지지하는 고상 성분, 및 상기 액상 성분과 고상 성분을 내장한 상태에서 선형 고분자와 가교 고분자가 점탄성 구조체를 형성하고 있는 폴리머 매트릭스의 3상(three-phase)으로 이루어져 있으며, 상기 폴리머 매트릭스는 양극 및 음극과 각각 결합하고 있고, 전극조립체의 제작 과정에서 분리층의 액상 성분이 전극으로 유입되어 전극의 wetting 특성이 매우 우수하게 개선되고, 이온 전도도가 향상되는 것을 특징으로 하는 일체형 전극조립체을 제공한다.
