Abstract
It is disclosed a method for producing a particulate metal M-based material, being hydroxide, oxyhydroxide, oxide, or any combination thereof, the method comprising (a) providing an aqueous solution (A<s>) and a precipitating agent, wherein the aqueous solution (A<s>) contains salts of metal M having Ni, Mn, Co in a molar ratio of 1-x-y : x : y, wherein 0.15≤1-x-y-z≤0.45, 0.55≤x≤0.85, 0.00≤y≤0.15; and (b) combining the aqueous solution (A<s>) and the precipitating agent at a pH value of less than 11.0, determined at 20°C, thereby obtaining a slurry comprising the particulate metal M-based material; wherein at least a portion of step (b) is performed in an ultrasonic environment.
