Abstract
(EN)
This negative electrode composition contains: a sulfide-based inorganic solid electrolyte; a negative electrode active material having silicon atoms or tin atoms; and a polymer, wherein the polymer exhibits substantially no adsorptive capacity with respect to the negative electrode active material and the sulfide-based inorganic solid electrolyte, and has an elastic modulus of 100-1000 MPa as measured in conformity with JIS K 7161 (2014), and is contained in the form of particles in a negative electrode active material layer formed of the negative electrode composition. The present invention also pertains to: a negative electrode sheet for a solid-state secondary battery; a solid-state secondary battery; and a method for producing a solid-state secondary battery negative electrode sheet or a solid-state secondary battery.
