Abstract:
A forming solution for forming a layer containing a solid electrolyte for an all-solid-state alkali metal secondary battery comprising a component derived from A2S and MxSy (A is selected from Li and Na; M is selected from P, Si, Ge, B, Al and Ga; and x and y are a number that gives a stoichiometric ratio in accordance with a species of M) as a starting material for manufacturing the solid electrolyte, a nonpolar organic solvent and a polar organic solvent having a polarity value higher than that of the nonpolar organic solvent by 0.3 or more.
