BINDER HAVING GOOD ADHESION FOR A SECONDARY BATTERY

The present invention relates to a binder for an electrode of a secondary battery, including polymer particles in which two or more types of monomers are polymerized with two or more types of cross-linking agents with mutually different molecular weights. The binder, through which the combination of the specific ingredients above, fundamentally improves electrode stability, starting from the manufacturing process of an electrode, to thereby provide a secondary battery with excellent cycle characteristics.
