Abstract
Provided are a binder composition for a secondary battery electrode that enables favorable dispersion of a conductive material when used in production of a slurry composition for a secondary battery electrode, and a slurry composition for a secondary battery electrode in which a conductive material is favorably dispersed. The binder composition for a secondary battery electrode contains a solvent and a copolymer including an alkylene structural unit and a nitrile group-containing monomer unit. The copolymer has a Mooney viscosity (ML1+4, 100° C.) of 40 or less. The slurry composition for a secondary battery electrode contains an electrode active material, a conductive material, the aforementioned binder composition for a secondary battery electrode, and a polymer other than the aforementioned copolymer.
