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.
