摘要： Disclosed is a binder for a secondary battery electrode including a copolymer of a hydrophilic monomer and a hydrophobic monomer, wherein, when a concentration of the copolymer is 5% in a solution based upon NMP as a solvent, a viscosity of the solution including the copolymer is 800 cP to 10000 cP. By using the binder, stability of an electrode is fundamentally improved from an electrode preparation process and, as such, a secondary battery having excellent lifespan characteristics is provided.

摘要： 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.
