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.

Abstract: Provided is a slurry composition for a secondary battery electrode that has excellent fibrous carbon nanomaterial dispersibility and is capable of forming an electrode mixed material layer having excellent close adherence to a current collector. The slurry composition is obtained using a conductive material paste composition for a secondary battery electrode that contains a fibrous carbon nanomaterial, a binder, and a solvent. The binder includes a first copolymer that includes an alkylene structural unit and a nitrile group-containing monomer unit and has a weight average molecular weight of at least 170,000 and less than 1,500,000.
