Claim Text:
1. A binder composition for an electrode of a non-aqueous electrolyte battery, the binder composition comprising a polymer A containing 80% by weight or more and 99.9% by weight or less of a repeating unit derived from a monomer including a nitrile group and 0.1% by weight or more and 20% by weight or less of a repeating unit derived from an ethylenically unsaturated compound, wherein a weight-average molecular weight of the polymer A is 500,000 to 2,000,000, a molecular weight distribution (Mw/Mn) of the polymer A is 13 or smaller, the binder composition further comprises a polymer B containing 10% by weight or more and 40% by weight or less of a repeating unit derived from acrylonitrile or methacrylonitrile, and the polymer B has an iodine number of 50 g/100 g or lower.
