Abstract
Official abstract text for this publication.
A method for producing a nickel-containing hydroxide is provided that includes a particle growth step of promoting growth of nickel-containing hydroxide particles by neutralization crystallization in an aqueous solution accommodated in an agitation tank. In the particle growth step, an averaged value of the maximum accelerations of the flows of streamlines for the aqueous solution is greater than 600 m/s 2 .
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a nickel-containing hydroxide, the method comprising: a particle growth step of promoting growth of nickel-containing hydroxide particles by neutralization crystallization in an aqueous solution accommodated in an agitation tank; wherein in the particle growth step, an averaged value of maximum accelerations of flows of streamlines for the aqueous solution is greater than 600 m/s 2 . 2. The method for producing a nickel-containing hydroxide according to claim 1 , wherein the nickel-containing hydroxide is produced so as to contain Ni, Co, and Al at an amount ratio of Ni:Co:Al=(1-x-y):x:y, where 0≤x≤0.3 and 0.005≤y≤0.15. 3. The method for producing a nickel-containing hydroxide according to claim 1 , wherein the nickel-containing hydroxide is produced so as to contain Ni, Co, Mn, and M, where M denotes at least one additional element selected from a group consisting of Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, and W, at an amount ratio of Ni:Co:Mn:M=x:y:z:t, where x+y+z+t=1, 0.1≤x≤0.7, 0.1≤y≤0.5, 0.1≤z≤0.8, and 0≤t≤0.02.
