Abstract
There is provided an organic/inorganic complex coating porous separator including a porous substrate, and an organic/inorganic complex coating layer formed in a single layer or multiple layers on a single surface or both surfaces of the porous substrate or at least a part of a pore portion of the porous substrate using a coating solution comprising a binder dispersed or suspended in a certain size and selectively comprising inorganic particles, and a secondary battery including the same. According to the present invention, since the coating solution comprising the binder dispersed in a certain size or less in a solvent is coated/dried on the porous substrate, a organic/inorganic complex coating porous separator having excellent air permeability and adhesive strength and a secondary battery including the organic/inorganic complex coating porous separator are provided.
