Composite separator including porous substrate, heat-resistant coating layer, and electrode adhesive layer and electrochemical device using the same
Provided are a separator for a secondary battery and an electrochemical device using the same. More specifically, provided is a composite separator having a more excellent cycle life and including a coating layer which is not easily swollen in an electrolyte solution. In the composite separator for a secondary battery according to an aspect of the present invention, distortion or lifting phenomenon is suppressed even when the heat and pressure are applied without significant decrease in permeability of the separator.
