Electrode composition, electrode sheet for all-solid state secondary battery, all-solid state secondary battery, and respective methods of manufacturing electrode composition, electrode sheet for all-solid state secondary battery, and all-solid state secondary battery

Abstract

Provided are an electrode composition, an electrode sheet for an all-solid state secondary battery, an all-solid state secondary battery, and respective methods of manufacturing the electrode composition, the electrode sheet for an all-solid state secondary battery, and the all-solid state secondary battery. The electrode composition includes: an inorganic solid electrolyte; an active material; and a distributing component that binds to the inorganic solid electrolyte and the active material, in which one kind of the distributing component is a binder, an adsorption rate A of the binder to the active material and an adsorption rate B of the binder to the inorganic solid electrolyte satisfy the following Expressions I) and II), and a distribution rate of the distributing component to the active material in an electrode active material layer formed of the electrode composition exceeds 50%. Adsorption Rate A≥20%   Expression I) Adsorption Rate A>Adsorption Rate B   Expression II)
