    摘要： The present invention provides a method for manufacturing a separator, comprising the steps of (S1) preparing a porous planar substrate having multiple pores; (S2) coating a coating solution obtained by dissolving a binder polymer in a solvent and dispersing inorganic particles therein on the porous substrate to form a porous coating layer and drying the porous coating layer; and (S3) applying a binder solution on the surface of the dried porous coating layer to form an adhesive layer, wherein the binder solution has a surface energy of at least 10 mN/m higher than that of the porous coating layer and a contact angle of the binder solution to the surface of the porous coating layer maintained at 80° or more for 30 seconds. In accordance with the present invention, a separator capable of obtaining sufficient adhesion force with minimizing the amount of an adhesive used for the adhesion with an electrode, and minimizing the deterioration of battery performances can be easily manufactured.
