Title:
BINDER COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY AND PRODUCTION METHOD THEREFOR, SLURRY COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY ELECTRODE, ELECTRODE FOR NON-AQUEOUS SECONDARY BATTERY, AND NON-AQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/153670
Kind Code:
A1
Abstract:
The binder composition for a non-aqueous secondary battery according to the present invention is characterized by comprising: a particulate polymer including a graft polymer having an acidic graft chain and obtained by causing an acidic group-containing monomer and/or a macromonomer to undergo a graft polymerization reaction with respect to core particles containing a block copolymer having an aromatic vinyl block domain including an aromatic vinyl monomeric unit and an aliphatic conjugated diene block domain including an aliphatic conjugated diene monomeric unit; and an acidic group-containing water-soluble polymer having a weight-average molecular weight of at most 200,000.
