Beschreibung
Zusammenfassung:	Provided is a transition metal oxide precursor comprising a core part and a shell part, wherein the core part comprises a compound of chemical formula 1 below, and the shell part comprises a compound of chemical formula 2 below. [Chemical formula 1] NiaMnbCo1-(a+b+c)Mc[OH(1-x)2-y]A(y/n). [Chemical formula 2] Nia'Mnb'Co1-(a'+b'+c')M'c'[OH(1-x')2-y']A'(y'/n). L'invention concerne un précurseur d'oxyde de métal de transition qui comprend une partie noyau et une partie enveloppe, la partie noyau comprenant un composé de formule chimique 1 ci-dessous, et la partie enveloppe comprenant un composé de formule chimique 2 ci-dessous. [Formule chimique 1] NiaMnbCo1-(a+b+c)Mc[OH(1-x)2-y]A(y/n). [Formule chimique 2] Nia'Mnb'Co1-(a'+b'+c')M'c'[OH(1-x')2-y']A'(y'/n). 코어부 및 쉘부를 포함하고, 상기 코어부는 하기 화학식 1의 화합물을 포함하고, 상기 쉘부는 하기 화학식 2의 화합물을 포함하는 전이금속 산화물의 전구체가 제공된다. [화학식 1] NiaMnbCo1-(a+b+c)Mc[OH(1-x)2-y]A(y/n) [화학식 2] Nia'Mnb'Co1-(a'+b'+c')M'c'[OH(1-x')2-y']A'(y'/n)
