Title:
BINDER COMPOSITION FOR ALL-SOLID-STATE SECONDARY BATTERY, SLURRY COMPOSITION FOR ALL-SOLID-STATE SECONDARY BATTERY, FUNCTIONAL LAYER FOR ALL-SOLID-STATE SECONDARY BATTERY, AND ALL-SOLID-STATE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/248698
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a binder composition for an all-solid-state secondary battery capable of giving excellent adhesive properties to a functional layer for an all-solid-state secondary battery while reducing internal resistance of the all-solid-state secondary battery. The present invention is a binder composition for an all-solid-state secondary battery comprising a copolymer that contains a nitrile group-containing monomer unit and a solvent. In the binder composition for an all-solid-state secondary battery, the solvent contains an ester solvent of C6 or higher, the content ratio of the nitrile group-containing monomer unit in the copolymer is 10-22 mass% inclusive when all repeating units in the copolymer are 100 mass%, and when the copolymer is dissolved in the solvent so that the tetrahydrofuran insoluble fraction of the copolymer is 0.5-3 mass% inclusive and the copolymer concentration is 8 mass%, the haze of the obtained copolymer solution is 30-80% inclusive.
