BINDER FOR SECONDARY BATTERY EXHIBITING EXCELLENT ADHESIVE FORCE

摘要

PURPOSE: A binder for a secondary battery is provided to improve the cycleability and the structural stability of an electrode by offering the superior supporting force of the binder to an active material. CONSTITUTION: A binder for a secondary battery contains a polymer particle obtained by polymerizing more than three kinds of monomers having the average particle diameter of 0.3-0.7 microns. The more than three kinds of monomers are a mixture of a (meth)acrylic acid ester-based monomer, an unsaturated monocarboxylic acid based monomer, and more than one monomer selected from the group consisting of an acrylate based monomer, a vinyl based monomer, and a nitrile based monomer.
