BINDER FOR A SECONDARY BATTERY HAVING SUPERIOR ADHESIVE FORCE |
摘要 |
Provided is a binder for secondary battery electrodes comprising polymer particles obtained by polymerizing (a) a (meth)acrylic acid ester monomer; (b) at least one monomer selected from the group consisting of an acrylate monomer, a vinyl monomer and a nitrile monomer; and (c) a (meth)acrylamide monomer and an unsaturated monocarbonic acid monomer, with two or more cross-linking agents with different molecular weights. Based on the combination of specific components, the binder basically improves stability of an electrode in the process of fabricating the electrode, thus providing secondary batteries with superior cycle properties. |
