Document Type and Number:
WIPO Patent Application WO/2021/065634
Kind Code:
A1
Abstract:
The present invention provides a slurry composition for a nonaqueous secondary battery electrode that has excellent stability and a binder composition for a nonaqueous secondary battery electrode capable of forming an electrode for a nonaqueous secondary battery having excellent peel strength after heating and drying. The binder composition for a nonaqueous secondary battery electrode of the present invention is characterized by including a particulate polymer A and a particulate polymer B, the particulate polymer A having a stem moiety, comprising a block copolymer including an aromatic vinyl monomer unit and an aliphatic conjugated diene monomer unit, and a graft moiety, and the particulate polymer B including aliphatic conjugated diene monomer units in a proportion of 70.0 mass% or higher and having a graft moiety.
