摘要：
The present invention is able to provide a method for producing an LGPS-type solid electrolyte, the method being characterized by comprising: a step in which a precursor is produced by mixing Li 3 PS 4 crystals having an average grain size (D50) of 0.1 to 5 µm and crystals that are formed of Li, Sn and S, while having an average grain size (D50) of 0.1 to 5 µm; and a step in which the precursor is subjected to the heat treatment at 300 to 700°C.
