Zusammenfassung:Presented are a method for manufacturing an electrode assembly and an electrochemical device comprising the electrode assembly, the method comprising at least one of the steps of: preparing a plurality of preliminary electrode assemblies having laminated first separators and electrodes, by pressing heat-treated first separators and electrodes by passing same through a pair of surface-patterned rollers; and pressing a second separator on which the preliminary electrode assemblies are disposed, by passing same through a pair of surface-patterned rollers, and thereafter winding so that the second separator is interposed between the preliminary electrode assemblies. Procédé de fabrication d'un ensemble électrode et dispositif électrochimique comprenant l'ensemble électrode, le procédé comprenant au moins l'une des étapes consistant : à préparer une pluralité d'ensembles électrodes préliminaires ayant des premiers séparateurs et des électrodes stratifiés, en pressant les premiers séparateurs et les électrodes traités thermiquement en les faisant passer à travers une paire de rouleaux à motifs en surface ; et à presser un second séparateur sur lequel les ensembles électrodes préliminaires sont disposés, en le faisant passer à travers une paire de rouleaux à motifs en surface, et par la suite à l'enrouler telle sorte que le second séparateur est interposé entre les ensembles électrodes préliminaires. 열처리된 제1 분리막과 전극을 표면이 패턴화된 한 쌍의 롤러 사이에 통과시켜 가압하여, 복수의 제1 분리막과 전극이 라미네이션된 예비 전극조립체를 준비하는 단계; 및 표면이 패턴화된 한 쌍의 롤러 사이에 상기 예비 전극조립체들이 배치된 제2 분리막을 통과시켜 가압하고, 이후 상기 예비 전극조립체들 사이에 상기 제2 분리막이 개재되도록 권취하는 단계; 중 1단계 이상을 포함하는 전극 조립체의 제조방법 및 상기 전극 조립체를 포함하는 전기화학소자가 제시된다.
