BINDER FOR A SECONDARY BATTERY HAVING SUPERIOR ADHESIVE FORCE

摘要

The present invention relates to a binder for an electrode of a secondary battery, comprising: polymer particles obtained by polymerizing a (meth)acrylic acid ester-based monomer; one or more monomers selected from a group consisting of an acrylate-based monomer, a vinyl-based monomer, and a nitrile-based monomer; a (meth)acrylamide-based monomer and an unsaturated monocarboxylic acid-based monomer; and two or more cross-linking agents having different molecular weights. The binder of the present invention, which is formed by combining the above-described specific components, fundamentally improves the stability of the electrode during the manufacturing processes of the electrode, thereby providing a secondary battery having superior cycle performance.
