Title:
BINDER COMPOSITION FOR ALL-SOLID-STATE SECONDARY BATTERIES, SLURRY COMPOSITION FOR ALL-SOLID-STATE SECONDARY BATTERIES, FUNCTIONAL LAYER FOR ALL-SOLID-STATE SECONDARY BATTERIES, AND ALL-SOLID-STATE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/249933
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a binder composition for all-solid-state secondary batteries, the binder composition being capable of preparing a slurry composition for all-solid-state secondary batteries, the slurry composition exhibiting excellent dispersibility, while enabling a functional layer for all-solid-state secondary batteries to exhibit excellent adhesiveness. A binder composition according to the present invention contains a binder and a solvent. The binder contains a polymer A; and the polymer A contains a nitrile group-containing monomer unit and a hydroxyl group-containing monomer unit. The content ratio of the nitrile group-containing monomer unit in the polymer A is from 3% by mass to 30% by mass; and the molar ratio of the content ratio of the hydroxyl group-containing monomer unit to the content ratio of the nitrile group-containing monomer unit is from 0.01 to 0.30.
