ELECTRODE COMPOSITION, ELECTRODE SHEET FOR ALL-SOLID STATE SECONDARY BATTERY, AND ALL-SOLID STATE SECONDARY BATTERY, AND MANUFACTURING METHODS FOR ELECTRODE SHEET FOR ALL-SOLID STATE SECONDARY BATTERY AND ALL-SOLID STATE SECONDARY BATTERY
Abstract:
There is provided an electrode composition containing a sulfide-based inorganic solid electrolyte, a polymer binder, an active material having a specific surface area of 10 m2/g or more, and a dispersion medium, in which a polymer that forms the polymer binder has a constitutional component derived from a (meth)acrylic monomer or vinyl monomer, which has an SP value of 19.0 MPa1/2 or more. There also provided an electrode sheet for all-solid state secondary battery and an all-solid state secondary battery, and manufacturing methods for an electrode sheet for an all-solid state secondary battery and an all-solid state secondary battery, in which the electrode composition is used.
