PREPARATION METHOD OF SEPARATOR, SEPARATOR FORMED THEREFROM, AND PREPARATION METHOD OF ELECTROCHEMICAL DEVICE CONTAINING THE SAME |
摘要 |
<p>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 slurry containing inorganic particles dispersed therein and a polymer solution including a first binder polymer and a second binder polymer in a solvent, and coating the slurry on at least one surface of the porous substrate, (S3) spraying a non-solvent incapable of dissolving the second binder polymer on the slurry, and (S4) simultaneously removing the solvent and the non-solvent by drying. According to the method, a separator with good bindability to electrodes can be manufactured in an easy manner. In addition, problems associated with the separation of inorganic particles in the course of manufacturing an electrochemical device can be avoided.</p> |
