Abstract

See full text

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.
