Abstract

Provided is a binder composition for a non-aqueous secondary battery electrode that can ensure excellent stability of a slurry composition for a non-aqueous secondary battery electrode while also inhibiting swelling of an electrode for a non-aqueous secondary battery associated with repeated charging and discharging and causing a non-aqueous secondary battery to display excellent cycle characteristics. The binder composition contains a particulate polymer A and a particulate polymer B. The particulate polymer A is a copolymer having a block region composed of an aromatic vinyl monomer unit. The particulate polymer B is a random copolymer including an aliphatic conjugated diene monomer unit and an aromatic vinyl monomer unit.
