Abstract
(EN)
A method for producing a sulfide-based inorganic solid electrolyte material, said method comprising: a step (A) for preparing a sulfide-based inorganic solid electrolyte material in a glass state; and a step (B) for annealing the sulfide-based inorganic solid electrolyte material in a glass state with use of a heating means. With respect to this method for producing a sulfide-based inorganic solid electrolyte material, the step (B) sequentially comprises in the following order: step (B1) for arranging the sulfide-based inorganic solid electrolyte material in a glass state in a heating space; a step (B2) for annealing the sulfide-based inorganic solid electrolyte material in a glass state, said inorganic solid electrolyte material being arranged within the heating space, while raising the temperature of the heating means from the initial temperature T0 to the annealing temperature T1; and a step (B3) for annealing the sulfide-based inorganic solid electrolyte material in a glass state, said inorganic solid electrolyte material being arranged within the heating space, at the annealing temperature T1. In the step (B2), the heating rate from the initial temperature T0 to the annealing temperature T1 is 2°C/minute or more.
