Title (EN) METHOD FOR MANUFACTURING ELECTRODE ASSEMBLY FOR SECONDARY BATTERY

Abstract: front page image
(EN)The present invention relates to a method for manufacturing a secondary battery. More particularly, the present invention relates to a method for manufacturing an electrode assembly by laminating multiple bi-cell type and/or mono-cell type unit cells. The electrode assembly manufacturing method according to the present invention is advantageous in that curvatures, which have occurred in the unit cells due to a roll lamination process, are easily removed, and a planar-shaped electrode assembly can be manufactured through a simple process. There is another advantage in that, when an electrode assembly is manufactured by the above method, curvatures between unit cells, which constitute the electrode assembly, counterbalance each other, thereby remarkably lengthening the period of time during which the electrode assembly maintains the planar shape.
(FR)La présente invention concerne un procédé de fabrication d'une batterie secondaire. Plus particulièrement, la présente invention concerne un procédé de fabrication d'un ensemble d'électrodes par laminage de multiples cellules unitaires de type bi-cellule et/ou de type mono-cellule. Le procédé de fabrication d'un ensemble d'électrodes selon la présente invention est avantageux en ce que des courbures, qui sont apparues dans les cellules unitaires en raison d'un processus de laminage au cylindre, sont facilement supprimées et qu'un ensemble d'électrodes de forme plane peut être fabriqué par un processus simple. La présente invention présente encore un autre avantage en ce que, lorsqu'un ensemble d'électrodes est fabriqué par le procédé susmentionné, les courbures entre des cellules unitaires, qui constituent l'ensemble d'électrodes, se compensent les unes les autres, ce qui allonge de manière remarquable la période de temps durant laquelle l'ensemble d'électrodes conserve sa forme plane.
(KO)본 발명은 이차 전지의 제조 방법에 대한 것이다. 더욱 상세하게는 다수의 바이셀 타입 및/또는 모노셀 타입인 단위셀을 적층하여 전극 조립체를 제조하는 방법에 대한 것이다. 본 발명에 따른 전극 조립체 제조 방법은 롤 라미네이션 공정에 의해 단위셀에 발생된 만곡을 용이하게 제거하고 간단한 공정에 의해 평면 형상의 전극 조립체를 제조할 수 있는 효과가 있다. 또한 상기 방법에 의해 전극 조립체를 제조하는 경우 전극 조립체를 구성하는 단위셀들간의 만곡이 서로 상쇄되므로 전극 조립체에서 평면 형상의 유지 기간이 현저하게 연장되는 효과가 있다.
