摘要： Provided are a separator for a secondary battery and an electrochemical device using the same. More particularly, a composite separator which has a lower Gurley permeability after curing than that before curing when forming a heat-resistant coating layer having low resistance, does not have a Gurley permeability which is greatly increased as compared with the Gurley permeability of a porous substrate itself before forming a coating layer to have an overall low Gurley permeability, and has a high surface hardness to have penetration stability, is provided.

摘要： Provided is an ultra large-width coating device applied to a consecutive process. More particularly, the present invention relates to a coating device capable of maximizing productivity by consecutively manufacturing a large-width film without reducing physical properties of the manufactured film by overcoming a problem in that a coating width is limited during a coating process using the existing contact type coating roller, and a method for manufacturing an ultra large-width membrane using the same.
