摘要：Disclosed is a method for manufacturing a separator. The method includes (S1)preparing a porous planar substrate having a plurality of pores, (S2) preparing a slurrycontaining inorganic particles dispersed therein and a polymer solution including a firstbinder polymer and a second binder polymer in a solvent, and sequentially coating theslurry on the porous substrate through a first discharge hole and a non-solvent incapableof dissolving the second binder polymer on the slurry through a second discharge holeadjacent to the first discharge hole, and (S3) simultaneously removing the solvent and thenon-solvent by drying. According to the method, a separator with good bindability toelectrodes can be manufactured in an easy manner. In addition, problems associated withthe separation of inorganic particles in the course of manufacturing an electrochemicaldevice can be avoided.
