Abstract:
(EN) Disclosed is a method for manufacturing a cathode active material powder of a secondary battery, the method comprising the steps of: preparing a mixed solution by mixing balls with a reaction solution containing a lithium ion, a transition metal ion, and a poly-anion; forming seeds by reacting the lithium ion, the transition metal ion, and the poly-anion in the mixed solution while stirring the mixed solution; forming an active material powder by spray-drying the mixed solution in which the seeds are formed; and heat-treating the active material powder.
(FR) L'invention concerne un procédé de fabrication d'une poudre de matériau actif de cathode d'une batterie secondaire, le procédé comprenant les étapes consistant à : préparer une solution mélangée par mélange de billes avec une solution de réaction contenant un ion lithium, un ion de métal de transition et un polyanion; la formation d'un germe par réaction de l'ion lithium, de l'ion de métal de transition et du polyanion dans la solution mélangée tout en agitant la solution mélangée; la formation d'une poudre de matériau actif par séchage par pulvérisation de la solution mélangée dans laquelle le germe est formé; et le traitement thermique de la poudre de matériau actif.
(KO) 리튬 이온, 전이금속 이온 및 다중산 음이온을 함유하는 반응용액과 볼들을 혼합하여 혼합용액을 제조하는 단계, 혼합용액을 교반하면서 혼합용액 내에 리튬 이온, 전이금속 이온 및 다중산 음이온을 반응시켜 씨드(seed)를 형성하는 단계, 씨드가 형성된 혼합용액을 분무건조하여 활물질 분말을 형성하는 단계 및 활물질 분말을 열처리하는 단계를 구비하는 이차전지 양극 활물질 분말의 제조방법이 개시된다.
