Abstract
Provided are a negative electrode composition including a sulfide-based inorganic solid electrolyte, a negative electrode active material containing a silicon atom or a tin atom, and a polymer, in which the polymer has substantially no adsorption capacity to the negative electrode active material and the sulfide-based inorganic solid electrolyte, a modulus of elasticity of the polymer measured in accordance with JIS K 7161 (2014) is 100 MPa or higher and 1000 MPa or lower, and in a case where a negative electrode active material layer is formed of the negative electrode composition, the polymer is contained in the negative electrode active material layer in a particle form, a negative electrode sheet for an all-solid state secondary battery, an all-solid state secondary battery, a method for manufacturing a negative electrode sheet for an all-solid state secondary battery, and a method for manufacturing an all-solid state secondary battery.
