Title:
BINDER COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY POSITIVE ELECTRODE, CONDUCTIVE MATERIAL DISPERSION FOR NONAQUEOUS SECONDARY BATTERY POSITIVE ELECTRODE, SLURRY COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY POSITIVE ELECTRODE, NONAQUEOUS SECONDARY BATTERY POSITIVE ELECTRODE, AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/162609
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a binder composition which is for a nonaqueous secondary battery positive electrode and from which a conductive material dispersion having excellent dispersibility of a conductive material can be prepared. A binder composition for a nonaqueous secondary battery positive electrode according to the present invention comprises a polymer, wherein: the polymer includes a nitrile group-containing monomer unit, an alkylene structural unit, and a hydrophilic group-containing monomer unit; the content of the hydrophilic group-containing monomer unit in the polymer is at least 6.5 mass%; and an 8 mass% aqueous solution of the polymer has a haze of at most 70% at a pH of 8.0 or higher.
