Abstract
A method for producing a metal-containing hydroxide or oxyhydroxide particulate material, the method comprising the steps of:(a) providing a first slurry comprising ammonia and particles of hydroxide or oxyhydroxide of metals M<sub>c</sub>;(b) reducing a level of ammonia (NH<sub>3(aq)</sub>) from at least a portion of the first slurry to obtain a seed slurry; and(c) combining the seed slurry with streams of an aqueous solution (A<sub>s</sub>) containing salts of metals M<sub>s</sub> and an aqueous solution (B<sub>s</sub>) containing a precipitating agent, thereby obtaining a second slurry comprising particles having a layer of hydroxide or oxyhydroxide of M<sub>s</sub> on the particles of the seed slurry,wherein the M<sub>c</sub>=Ni<sub>1-xc-yc-zc</sub>Mn<sub>xc</sub>Co<sub>yc</sub>A<sub>zc</sub> with 0≤xc≤0.85, 0≤yc≤0.35, 0≤zc<0.1, and 0.15≤1-xc-yc-zc≤1; andwherein the M<sub>s</sub>=Ni<sub>1-xs-ys-zs</sub>Mn<sub>xs</sub>Co<sub>ys</sub>A<sub>zs</sub> with 0.55≤xs≤0.85, 0≤ys≤0.35, 0≤zs<0.1, and 0.15≤1-xs-ys-zs≤0.45.
