Abstract

Disclosed is an electrode assembly manufacturing method, in which, in a step of stacking and pressing electrodes and a separator, the pressing is performed in that state in which pores of a porous substrate are filled with a polymer solution. The form or volume of the pores is not changed due to the polymer solution. Consequently, porosity of the separator after manufacture of an electrode assembly is similar to porosity of the separator before stacking. As a result, a battery including the electrode assembly has high ionic conductivity and excellent performance.
