Binder composition for non-aqueous secondary battery electrode, slurry composition for non-aqueous secondary battery electrode, electrode for non-aqueous secondary battery, and non-aqueous secondary battery

Abstract

Provided is a binder composition for a non-aqueous secondary battery electrode with which it is possible to form an electrode having excellent electrolyte solution injectability and process adhesiveness. The binder composition for a non-aqueous secondary battery electrode contains a particulate polymer formed by a polymer that includes a block region composed of an aromatic vinyl monomer unit and has a tetrahydrofuran-insoluble content of not less than 5 mass % and not more than 40 mass %. The binder composition for a non-aqueous secondary battery electrode preferably further contains a water-soluble polymer that includes a hydrophilic group and has a weight-average molecular weight of not less than 15,000 and not more than 500,000.
