Document Type and Number:
WIPO Patent Application WO/2021/241599
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a slurry composition for all-solid-state secondary batteries, said slurry composition being capable of forming a solid electrolyte-containing layer that enables an all-solid-state secondary battery to exhibits excellent output characteristics and excellent cycle characteristics. A slurry composition according to the present invention contains a solid electrolyte, a particulate polymer and an organic solvent. The particulate polymer has a core/shell structure which comprises a core part and a shell part that covers at least a part of the outer surface of the core part; a polymer that constitutes the core part has a glass transition temperature of from -60°C to -10°C; and a polymer that constitutes the shell part has a glass transition temperature of from 15°C to 100°C. In addition, the polymer that constitutes the shell part contains from 10% by mass to 90% by mass of a nitrogen functional group-containing monomer unit.
