Abstract
To provide a composite solid electrolyte layer with a balance between electrical conductivity and deformability, a method for producing the composite solid electrolyte layer, and a method for producing an all-solid-state battery comprising the composite solid electrolyte layer. Disclosed is a method for producing a composite solid electrolyte layer for all-solid-state batteries, herein the method comprises: preparing a solid electrolyte, preparing a three-dimensional porous film containing a resin, forming a precursor of the composite solid electrolyte layer by bringing the solid electrolyte into contact with the three-dimensional porous film, and applying pressure to the precursor while heating the precursor at a temperature which is 80° C. or more and which is less than a softening temperature of the three-dimensional porous film; wherein a pore diameter of the three-dimensional porous film is more than 2 μm; and wherein the softening temperature of the three-dimensional porous film is lower than a crystallization temperature of the solid electrolyte.
