Abstract
An embodiment provides a binder for a non-aqueous electrolyte rechargeable battery including a copolymer (A) and a copolymer (B), wherein the copolymer (A) includes a unit (a-1) derived from a (meth)acrylic acid-based monomer, and a unit (a-2) derived from a (meth)acrylonitrile monomer, and the copolymer (B) includes a unit (b-1) derived from an aromatic vinyl-based monomer; and a unit (b-2) derived from an ethylenic unsaturated monomer which is at least one of an unsaturated carboxylic acid alkylester monomer, a (meth)acrylic acid-based monomer, a unsaturated carboxylic acid amide monomer, or combinations thereof.
