Beschreibung
Zusammenfassung:	The present invention relates to a positive electrode active material including secondary particles formed by aggregation of a plurality of primary particles, wherein at least a part of the primary particles has a radial arrangement structure, and specifically, to a positive electrode active material for an all-solid-state battery, a method for manufacturing the same, and an all-solid-state battery including the same, wherein the positive electrode active material for an all-solid-state battery includes: a first boron coating unit present on the surface of the secondary particles; and a second boron coating unit present on the surface of the primary particles inside the secondary particles. 복수의 1차 입자들이 응집되어 이루어지고, 상기 1차 입자들의 적어도 일부분이 방사형 배열 구조를 갖는 2차 입자를 포함하는 양극 활물질로서, 상기 양극 활물질은 상기 2차 입자의 표면에 존재하는 제1 보론 코팅부, 및 상기 2차 입자 내부의 1차 입자들의 표면에 존재하는 제2 보론 코팅부를 포함하는, 전고체 전지용 양극 활물질과 이의 제조 방법 및 이를 포함하는 전고체 전지에 관한 것이다.
