Abstract
Provided are composite particles for an all-solid-state secondary battery electrode with which it is possible to form an electrode for an all-solid-state secondary battery that can cause an all-solid-state secondary battery to display excellent output characteristics, and a method of producing these composite particles. The composite particles for an all-solid-state secondary battery electrode contain an electrode active material, a binder, and an inorganic solid electrolyte that is distributed more in an outer part than in an inner part, and have a volume-average particle diameter of not less than 5 μm and not more than 90 μm. The method of producing the composite particles for an all-solid-state secondary battery electrode includes granulating a slurry composition containing an electrode active material and a binder to obtain base particles and externally adding an inorganic solid electrolyte to the base particles.
