Abstract

Disclosed are a method for manufacturing a separator and a separator obtained thereby. The method includes forming a porous coating layer by using slurry for forming a porous coating layer including inorganic particles, lithium halide and a polyvinylidene fluoride-based binder polymer. It is possible to provide a separator showing reduced resistance and an electrochemical device including the same by modifying the properties of the binder polymer.
