Abstract:
The present invention relates to a binder composition for a secondary battery, including: a copolymer having a functional group; and an alkali metal ion bound to the functional group of the copolymer or with which a constituent element of the functional group is substituted. The binder composition exhibits enhanced adhesive strength and also exhibits low resistance due to the alkali metal ion included in the copolymer, and thus may exhibit more stable electrochemical performance.

Claim (Index 1):
A binder composition for a secondary battery comprising:\n a copolymer having a functional group; and an alkali metal ion bound to the functional group of the copolymer or with which a constituent element of the functional group is substituted, wherein the alkali metal ion is included in an amount of 0.2 parts by weight to 5 parts by weight with respect to 100 parts by weight of the copolymer, and the copolymer comprises three or more selected from the group consisting of: (a) a repeating unit derived from a conjugated diene-based monomer or a unit derived from a conjugated diene-based polymer; (b) a repeating unit derived from a (meth)acrylic acid ester-based monomer; (c) one or more repeating units selected from the group consisting of a repeating unit derived from a vinyl-based monomer, a repeating unit derived from a (meth)acrylamide-based monomer, and a repeating unit derived from a nitrile-based monomer; and (d) a repeating unit derived from an unsaturated carboxylic acid-based monomer.
