Document Type and Number:
WIPO Patent Application WO/2021/080258
Kind Code:
A1
Abstract:
The present invention relates to a method of manufacturing an electrode assembly in which pressing is performed by filling, with a polymer solution, pores of a separator porous substrate that will be used as a separator during the steps of laminating and pressing an electrode and a separator. In the present invention, the shape or volume of the pores does not change due to the polymer solution. Accordingly, the porosity of the separator after being manufactured as an electrode assembly maintains a value similar to that of the separator before the lamination. To this end, the electrode assembly according to the present invention has high ionic conductivity in batteries and excellent performance.
