Abstract
A method for producing an all solid state battery using a precipitation-dissolution reaction of metallic Li as a reaction of an anode, includes a preparation step, a liquid composition preparation step, a coating layer formation step, and a separator formation step. The preparation step includes preparing a sulfide solid electrolyte represented by LiPSX(X is at least one of Cl, Br, and I, and a satisfies 0≤a≤2), the liquid composition preparation step includes dissolving the sulfide solid electrolyte in an alcohol-based solvent to prepare a liquid composition, the coating layer formation step includes applying the liquid composition to an anode current collector to form a coating layer, the separator formation step includes forming a separator by volatilizing the alcohol-based solvent from the coating layer by drying, and the ratio of the sulfide solid electrolyte contained in the liquid composition is 10% by weight to 30% by weight.
