Summary:To provide a separator for a secondary battery, a method of manufacturing the same, and a lithium secondary battery including the same.SOLUTION: The separator for a secondary battery includes a porous substrate and a coating layer formed on the porous substrate. The coating layer includes a plurality of inorganic particles, and a binder binding the plurality of inorganic particles. The binder includes a copolymer of a monomer mixture containing an acrylamide monomer, a vinyl cyan monomer, and an acrylic monomer having a carboxyl group.SELECTED DRAWING: None 【課題】二次電池用セパレータ、その製造方法、およびそれを含むリチウム二次電池を提供する。【解決手段】多孔性基材と、前記多孔性基材上に形成されたコーティング層と、を含むセパレータであって、前記コーティング層は、複数の無機粒子、および前記複数の無機粒子を結着するバインダーを含み、前記バインダーは、アクリルアミド系単量体、ビニルシアン系単量体、およびカルボキシル基を有するアクリル系単量体を含む単量体混合物の共重合体を含む、二次電池用セパレータに関する。【選択図】 なし
