Abstract
Disclosed are a binder with a core-shell structure for a secondary battery electrode, and a secondary battery including the same, wherein the core includes styrene-butadiene rubber (SBR), the shell includes a copolymer of two or more monomers selected from the group consisting of a conjugated diene-based monomer, a (meth)acrylic ester-based monomer, an acrylate-based monomer, a vinyl-based monomer, a nitrile-based monomer, and an ethylenically unsaturated carboxylic acid monomer, and the binder includes a functional group providing binding capacity to surfaces of the SBR particles. Such a binder provides excellent adhesive strength and elasticity and, thus, overall performance of a secondary battery including the same may be improved.
