Conductive material paste composition for secondary battery electrode, slurry composition for secondary battery electrode, current collector with undercoat layer for secondary battery electrode, electrode for secondary battery, and secondary battery

摘要

An object of this invention is to provide the slurry composition which can form the electrode compound-material layer which is excellent in the dispersibility of fibrous carbon nanomaterial, and is excellent in adhesiveness with a collector. The slurry composition for a secondary battery electrode of the present invention includes a fibrous carbon nanomaterial, a binder, and a solvent, and the binder contains an alkylene structural unit and a nitrile group-containing monomer unit. And a conductive material paste composition for a secondary battery electrode, comprising a first copolymer having a weight average molecular weight of 170,000 or more and less than 1500,000.
