Non-aqueous secondary battery electrode binder composition, non-aqueous secondary battery electrode slurry composition, non-aqueous secondary battery electrode, non-aqueous secondary battery negative electrode and non-aqueous secondary battery, and non-aqueous secondary Manufacturing method of battery electrode

摘要

The present invention ensures excellent stability of the slurry composition for a non-aqueous secondary battery electrode, and suppresses the non-aqueous secondary battery electrode from swelling due to repetition of charge and discharge. An object of the present invention is to provide a binder composition for a non-aqueous secondary battery electrode that can exhibit excellent cycle characteristics. The binder composition of the present invention comprises a particulate polymer A and a particulate polymer B, wherein 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 containing an aliphatic conjugated diene monomer unit and an aromatic vinyl monomer unit.
