    Abstract: Provided are a separator, a lithium secondary battery employing the same, and a method of preparing the separator. The separator includes: a porous substrate; and a coating layer arranged on at least one surface of the porous substrate, wherein the coating layer includes a binder and inorganic particles, the binder includes an aqueous cross-linking reactive polyacrylamide-based copolymer, and the polyacrylamide-based copolymer includes at least two cross-linking reactive groups cross-linkable with each other, a weight ratio of the binder to the inorganic particles is about 1:10 to about 1:35, and a thickness of the coating layer is greater than 0.5 μm and no greater than 4 μm. The separator has significantly improved thermal resistance characteristics and low resistance, and therefore, a lithium secondary battery with improved battery stability and lifespan characteristics at the same time may be provided.

    Abstract: The separator includes: a porous substrate; a first coating layer arranged on at least one surface of the porous substrate, the first coating layer including a binder and inorganic particles, wherein the binder includes a cross-linked product of an aqueous cross-linking reactive poly(vinylamide)-based copolymer, wherein the poly(vinylamide)-based copolymer includes repeating units derived from vinylamide monomers and repeating units derived from cross-linking reactive group-containing monomers, and is cross-linked by the cross-linking reactive groups; and a second coating layer arranged on both surfaces of the porous substrate on which the first coating layer is arranged, the second coating layer including an acrylic copolymer and a polyvinylidene fluoride-based binder in a weight ratio of greater than 1:1 and less than 1:4. The separator has high thermal resistance characteristics and enhanced electrode plate adhesion, and therefore, a lithium battery having excellent lifespan characteristics may be provided.
