Title:
非水系電池電極用バインダー用共重合体、非水系電池電極用スラリー、非水系電池電極、および非水系電池
Document Type and Number:
Japanese Patent JP6872525
Kind Code:
B2
Abstract:
The invention relates to a copolymer for binders, which is capable of reducing the internal resistance of a battery, while ensuring sufficient binding properties 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 for binders (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 an amount of structure derived from the monomer (A) based on the copolymer for binders (P) is set to 0.5 to 20.0% by mass. (In the formula, each of R 1 and R 2 independently represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms.)
