Title:
BINDER AGENT COMPOSITION FOR LITHIUM BATTERY ELECTRODE, AND ELECTRODE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/143383
Kind Code:
A1
Abstract:
The purpose of the invention is to provide: an excellent binder agent composition that overcomes such problems as a reduction in charge/discharge capacity; a slurry composition and an electrode using said binder agent composition; and a method for preparing said electrode. This invention relates to: "a binder agent composition comprising a copolymer including, as constituent components, an acrylic acid-derived monomer unit and one or two types of monomer units derived from a compound represented by general formula (I) etc., a bivalent to decavalent alcohol, and water (in the formula, R1 represents a hydrogen atom or a methyl group (if R2 is a hydrogen atom, R1 represents a methyl group), and R2 is, for example, a hydrogen atom, an alkyl group, a fluorine atom, or an alkyl group substituted by a hydroxy group)"; "a slurry composition for lithium batteries, comprising (1) a carbon-containing active material, (2) an electroconductive aid, and (3) said binder agent composition"; "an electrode for lithium batteries, comprising (1) a carbon-containing active material, (2) an electroconductive aid, (3) a binder agent derived from said binder agent composition, and (4) a charge collector"; and "a method for preparing an electrode for lithium batteries, characterized by applying said slurry composition on a charge collector, and then drying the same."
