Abstract
The present disclosure relates to a method for manufacturing an electrode assembly for an electrochemical device. More particularly, the present disclosure relates to a method for manufacturing a curved electrode assembly having a curve with a uniform curvature radius. According to the present disclosure, as the curved electrode assembly is manufactured by stacking a plurality of curved unit cells having a uniform curvature radius, restoration to the original shape is low and shape stability is high as compared to an electrode assembly manufactured by bending a flat electrode assembly. In addition, as unit cells included in an electrode assembly are produced to have a curve by a roll lamination process under a uniform condition and they have the same curvature radius or a small difference in curvature radius, it is possible to easily manufacture an electrode assembly having a desired curvature radius without excessive deformation of the unit cells.
