Abstract

Provided is a binder composition for secondary battery electrode-use that has high binding capacity, and that is capable of suppressing corrosion of a current collector and an increase in internal resistance when used in production of a secondary battery. The binder composition for secondary battery electrode-use contains a copolymer and a dispersion medium. The copolymer includes at least 5 mass % and no greater than 80 mass % of a constitutional unit represented by formula (I) and at least 5 mass % and no greater than 90 mass % of a constitutional unit represented by formula (II).
