Beschreibung
Zusammenfassung:	The present invention provides a method for coating sulfide-based solid electrolyte powder having excellent moisture barrier properties, a sulfide-based solid electrolyte coating powder manufactured therefrom, and an all-solid-state battery. The method for coating sulfide-based solid electrolyte powder includes a step of forming an inorganic oxide coating on the surface of the sulfide-based solid electrolyte powder through an atomic layer deposition (ALD) process. The present invention can form a uniform coating. 본 발명은 수분 차단성이 우수한 황화물계 고체전해질 분말의 코팅 방법, 그로부터 제조된 황화물계 고체전해질 코팅 분말 및 전고체전지를 제공한다.
