Title:

COPOLYMER FOR BINDERS FOR NONAQUEOUS BATTERY ELECTRODES, SLURRY FOR NONAQUEOUS BATTERY ELECTRODES, NONAQUEOUS BATTERY ELECTRODE, AND NONAQUEOUS BATTERY

Document Type and Number:

WIPO Patent Application WO/2017/150200

Kind Code:

A1

Abstract:

To provide: a copolymer for binders, which is capable of reducing the internal resistance of a battery, while ensuring sufficient bonding adhesion between active materials and between an active material and a collector in a nonaqueous battery electrode; a composition for binders; a slurry for nonaqueous battery electrodes; a nonaqueous battery electrode; and a nonaqueous battery. This copolymer for binders is a copolymer (P) of a monomer mixture (M) that contains at least a monomer (A) represented by general formula (1) and a (meth)acrylate salt monomer (B); and the ratio of the structure derived from the monomer (A) relative to the copolymer (P) is set to 0.5-20.0% by mass. (In the formula, each of R1 and R2 independently represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms (inclusive).)
