The present invention is a binder for the electrode of the secondary battery, the gel content comprising a polymer particle copolymerized three or more monomers is 50 to 100%, the swelling degree of the electrolyte solution characterized in that the 1.1 to 5.0 Provided are binders for electrodes. Such a binder, by the gel content as described above, the chemical resistance is increased to fundamentally improve the stability of the electrode from the manufacturing process of the electrode, the ionic conductivity is increased by the swelling degree to provide a secondary battery excellent in cycle characteristics. . |
