Beschreibung
Zusammenfassung:	The present invention provides a precursor for preparation of cathode active material, the precursor being characterized by particles comprising a central part and a surface part in sequence from the center to the outer surface thereof, and the density of the surface part being relatively low when compared to that of the central part. La présente invention concerne un précurseur pour la préparation d'un matériau actif de cathode, le précurseur étant caractérisé par des particules comprenant une partie centrale et une partie de surface en séquence du centre à la surface externe de celui-ci, et la densité de la partie de surface étant relativement faible par rapport à celle de la partie centrale. 본 발명은, 양극 활물질의 제조를 위한 전구체로서, 입자의 중앙으로부터 외면 방향으로 중심부와 표면부가 순차적으로 형성되어 있고, 상기 표면부는 중심부와 비교할 때 상대적으로 저밀도로 이루어진 것을 특징으로 하는 양극 활물질 제조용 전구체를 제공한다.
