Zusammenfassung:The present invention relates to a method for manufacturing a solid electrolyte, the method including the steps of (S1) mixing sulfide-based solid electrolyte raw materials with a solvent to prepare a precursor mixture and (S2) thermally treating the precursor mixture, wherein the solvent has a relative polarity to water of 0.15 or less, with the content thereof ranging 2 wt% (exclusive) to 5 wt% (inclusive) on the basis of the total weight of the precursor mixture. La présente invention concerne un procédé de fabrication d'un électrolyte solide, le procédé comprenant les étapes consistant à (S1) mélanger des matières premières d'électrolyte solide à base de sulfure avec un solvant pour préparer un mélange précurseur et (S2) traiter thermiquement le mélange précurseur, le solvant présentant une polarité relative à l'eau de 0,15 ou moins, sa teneur allant de 2 % en poids (exclus) à 5 % en poids (inclus) sur la base du poids total du mélange précurseur. 본 발명은 황화물계 고체 전해질 원료물질 및 용매를 혼합하여 전구체 혼합물을 제조하는 단계(S1) 및 상기 전구체 혼합물을 열처리하는 단계(S2)를 포함하고, 상기 용매는 물에 대한 상대 극성도가 0.15 이하이며, 상기 용매의 함량은 상기 전구체 혼합물의 전체 함량에 대하여 2 중량% 초과 5 중량% 이하인 것인 고체 전해질 제조방법에 관한 것이다.
