Abstract

The present disclosure provides a method for manufacturing a separator, the method including (S10) preparing a separator coating slurry composition including pore-inducing particles; inorganic particles; a particle-type binder and a solvent; (S20) applying the separator coating slurry composition to at least one surface of a porous polymer substrate to form a porous coating layer; (S30) removing at least some of the pore-inducing particles of the porous coating layer by an etching solution; and (S40) drying the porous coating layer from which the at least some of the pore-inducing particles have been removed.
