Title:
BINDER COMPOSITION FOR SECONDARY BATTERIES, SLURRY COMPOSITION FOR SECONDARY BATTERIES, NEGATIVE ELECTRODE FOR SECONDARY BATTERIES, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2014/141721
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a binder composition for secondary batteries, which has excellent binding properties and is capable of improving the electrical characteristics of a secondary battery if used for the formation of a battery member. A binder composition for secondary batteries of the present invention contains: a water-soluble thickening agent (A) that has a hydroxyl group or a carboxyl group; a crosslinking agent (B) that has a functional group which is reactive with the hydroxyl group or the carboxyl group of the water-soluble thickening agent (A); and a particulate polymer (C). The particulate polymer (C) has a functional group that is reactive with the crosslinking agent (B), and contains an aliphatic conjugated diene monomer unit and an aromatic vinyl monomer unit. This binder composition for secondary batteries contains 0.001 part by mass or more but less than 100 parts by mass of the crosslinking agent (B) and 10 parts by mass or more but less than 500 parts by mass of the particulate polymer (C) per 100 parts by mass of the water-soluble thickening agent (A).
