Title:
BINDER COMPOSITION FOR ELECTROCHEMICAL ELEMENT, CONDUCTIVE MATERIAL DISPERSION LIQUID FOR ELECTROCHEMICAL ELEMENT, SLURRY FOR ELECTROCHEMICAL ELEMENT ELECTRODE, ELECTRODE FOR ELECTROCHEMICAL ELEMENT, AND ELECTROCHEMICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/276709
Kind Code:
A1
Abstract:
The present invention provides a binder composition that can be used to prepare a conductive material dispersion liquid having excellent dispersibility, and that can exhibit cycle characteristics excellent for an electrochemical element. A binder composition according to the present invention contains a first polymer, a second polymer, and an organic solvent. The first polymer includes a nitrile group-containing monomer unit and also includes an aliphatic conjugated diene monomer unit and/or an alkylene structural unit. The second polymer contains a structural unit of formula (I) at a proportion of 70-95 mass%. Note that in formula (I): R1 represents a hydrogen atom or a methyl group; R2 represents a hydrogen atom, a phenyl group, a 1-6C alkyl group, or a phenyl group having one to three 1-6C alkyl groups; and n is an integer of 3 or higher.
