"textContent": "The present disclosure relates to a method for manufacturing a separator for a lithium secondary battery. Particularly, the method for manufacturing a separator for a lithium secondary battery includes the steps of: preparing slurry for forming a porous coating layer which includes inorganic particles dispersed in an asymmetric linear ketone solvent and a binder polymer, comprising a first binder polymer and a second binder polymer, dissolved therein; and applying the slurry for forming a porous coating layer onto a porous polymer substrate having a plurality of pores, followed by drying.According to an embodiment of the present disclosure, slurry for forming a porous coating layer is prepared by dissolving a first binder polymer and a second binder polymer having predetermined properties in an asymmetric ketone solvent, and a separator may be obtained by using the slurry for forming a porous coating layer. In this manner, it is possible to improve the adhesion (Lami strength) to an electrode and to increase the compression resistance of the separator.",
