Summary:An electrode assembly preparation method and an electrode assembly pressing apparatus are disclosed. According to the present invention, an electrode assembly having a curved surface which has a radius of curvature in accordance with an originally intended radius of curvature can be prepared. According to the present invention, an electrode assembly having a curved surface which has a uniform radius of curvature can be prepared by means of reducing or eliminating the differential between the radius of curvature of the central part of the electrode assembly and the radius of curvature of the both end parts of the electrode assembly. According to an aspect of the present invention for attaining the purpose, provided is an electrode assembly preparation method comprising: a step for preparing an electrode assembly, which comprises an electrode and a separator membrane, and a pressing means which is for pressing the electrode assembly; and a pressing step for forming a curved surface on the electrode assembly by pressing the upper surface or the lower surface of the electrode assembly by means of the pressing means, wherein, in the pressing step, a plurality of areas positioned away from one another are pressed from the upper surface or the lower surface of the electrode assembly by means of the pressing means and the gap between the plurality of areas is not pressed. L'invention concerne un procédé de préparation d'ensemble électrode et un appareil de pressage d'ensemble électrode. Selon l'invention, un ensemble électrode comportant une surface incurvée ayant un rayon de courbure en conformité avec un rayon de courbure initialement prévu peut être préparé. Selon la présente invention, un ensemble électrode comportant une surface incurvée qui présente un rayon uniforme de courbure peut être préparé en réduisant ou supprimant le différentiel entre le rayon de courbure de la partie centrale de l'ensemble électrode et le rayon de courbure des deux parties d'extrémité de l'ensemble électrode. À cet effet, un aspect de l'invention concerne un procédé de préparation d'ensemble électrode comprenant : une étape de préparation d'un ensemble électrode, qui comporte une électrode et une membrane séparatrice, et d'un moyen de pression destiné à presser l'ensemble électrode ; et une étape de pressage consistant à former une surface incurvée sur l'ensemble électrode par pression de la surface supérieure ou inférieure de l'ensemble électrode à l'aide du moyen de pression, dans l'étape de pressage, une pluralité de zones éloignées les unes des autres sont pressées à partir de la surface supérieure ou inférieure de l'ensemble électrode à l'aide du moyen de pression et l'espace entre la pluralité de zones n'est pas pressé. 전극 조립체 제조 방법 및 전극 조립체 가압 장치가 개시된다. 본 발명에 따르면, 원래 형성하고자 하였던 곡률 반경에 부합하는 곡률 반경을 갖는 곡면이 형성되는 전극 조립체를 제조할 수 있다. 또한, 본 발명에 따르면 전극 조립체의 중앙부의 곡률 반경 및 전극 조립체의 양끝부의 곡률 반경 간의 차이를 줄이거나 없앰으로써 균일한 곡률 반경을 갖는 곡면이 형성되는 전극 조립체를 제조할 수 있다. 상기 목적을 달성하기 위한 본 발명의 일 측면에 따르면, 전극과 분리막을 포함하는 전극 조립체 및 상기 전극 조립체를 가압하는 가압 수단을 준비하는 단계; 및 상기 가압 수단을 이용하여 상기 전극 조립체의 상면 또는 하면을 가압하여 전극 조립체에 곡면이 형성되도록 하는 가압 단계; 를 포함하고, 상기 가압 단계는, 상기 가압 수단을 통해 상기 전극 조립체의 상면 또는 하면에서 서로 이격된 복수 영역들을 가압하고, 상기 복수 영역들 사이는 가압하지 않는 전극 조립체 제조방법이 제공된다.
