Abstract
Official abstract text for this publication.
Provided are a binder composition for an all-solid-state secondary battery with which it is possible to obtain an all-solid-state secondary battery that has good battery characteristics and for which processability during all-solid-state secondary battery production is excellent, a slurry composition for an all-solid-state secondary battery that contains this binder composition for an all-solid-state secondary battery, a functional layer for an all-solid-state secondary battery that is formed from this slurry composition for an all-solid-state secondary battery, and an all-solid-state secondary battery that includes this functional layer for an all-solid-state secondary battery. The binder composition for an all-solid-state secondary battery contains a polymer, an unsaturated acid metal salt monomer, and a solvent. The unsaturated acid metal salt monomer includes a divalent metal.
First claim
Opening claim text (preview).
1 . A binder composition for an all-solid-state secondary battery comprising a polymer, an unsaturated acid metal salt monomer, and a solvent, wherein the unsaturated acid metal salt monomer includes a divalent metal. 2 .
