Binder composition for all-solid-state secondary battery, solid-state electrolyte-containing sheet and all-solid-state secondary battery, and method for producing solid-state electrolyte-containing sheet and all-solid-state secondary battery.

摘要

A binder composition for an all-solid-state secondary battery containing a polymer particle (A) and a non-aqueous dispersion medium (B), wherein the polymer particle (A) does not have a surfactant and is a dynamic light scattering type. A graft polymer that shows two or more peaks in the scattering intensity distribution measured by a particle size distribution measuring device, and has a water content of 100 ppm or less on a mass basis, a binder composition for an all-solid-state secondary battery, and a solid electrolyte. A method for producing a containing sheet and an all-solid secondary battery, and a solid electrolyte-containing sheet and an all-solid-state secondary battery.
