<p>[Problem] To provide an aqueous binder composition for secondary battery cathode that is excellent in long-term storage stability, and capable of improving the cycling characteristics and safety of the obtained secondary battery; slurry composition for secondary battery cathode using the binder composition; a secondary battery cathode; and a secondary battery. [Solution] This aqueous binder composition for secondary battery cathode is characterized by including: a binder containing a (meth)acrylic ester monomer unit, a vinyl monomer unit having an acidic group, and an a,ß-unsaturated nitrile monomer unit; and 0.001 to 1.0 part by weight of isothiazoline compound and 0.001 to 1.0 part by weight of chelate compound, based on 100 parts by weight of the binder.</p> |
