  • Publication number: 20210296651
    Abstract: The present invention relates to a copolymer for a binder for a non-aqueous battery electrode, which ensures sufficient binding properties between active materials and between the active materials and a current collector, suppresses generation of aggregates in a slurry containing the electrode active material, suppresses generation of cracks in an electrode active material layer, and sufficiently ensures peel strength of the electrode active material layer against the current collector. The copolymer for a binder for a non-aqueous battery electrode is a copolymer (P) of a monomer mixture (M) containing a monomer (A) represented by general formula (1), a (meth)acrylic acid monomer (B), and a monomer (C) represented by general formula (2), wherein a content of a structure derived from the monomer (A) in the copolymer (P) is 0.5 to 20.0 mass % and a content of a structure derived from the monomer (C) in the copolymer (P) is 0.5 to 20.0 mass %.

  • Publication number: 20200395613
    Abstract: The invention relates to a method for producing a slurry for a nonaqueous battery electrode, a method for producing a nonaqueous battery electrode, and a method for producing a nonaqueous battery. The method for producing a slurry for a nonaqueous battery electrode includes a dispersing step of dispersing a conductive auxiliary agent in an aqueous binder composition, and a mixing step of mixing the conductive auxiliary agent-containing binder composition obtained in the dispersing step with an active material. In the conductive auxiliary agent-containing binder composition, a particle diameter at which particles begin to appear, which is measured according to a degree of dispersion by a grain gauge method, is 90 ?m or less.
