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 capable of forming an electrode for a non-aqueous secondary battery that has excellent peel strength and can cause a non-aqueous secondary battery to display excellent cycle characteristics. The binder composition for a non-aqueous secondary battery electrode contains: a first particulate polymer including an aliphatic conjugated diene monomer unit in a proportion of more than 90 mass % and having a volume average particle diameter of at least 0.6 μm and not more than 2.5 μm; and a second particulate polymer including an aliphatic conjugated diene monomer unit in a proportion of at least 20 mass % and not more than 60 mass % and having a volume average particle diameter of at least 0.01 μm and not more than 0.5 μm.

Dependencies are inferred from the claim text.
