Abstract: Process for precipitating a mixed hydroxide of TM wherein TM comprises Ni and at least one of Co and Mn and, optionally, Al, Mg, Zr or Ti, from an aqueous solution of salts of such transition metals or of Al or of Mg, wherein such process is carried out in a stirred vessel and comprises the step of introducing an aqueous solution of alkali metal hydroxide and an aqueous solution of transition metal salts through at least two inlets into said stirred vessel wherein the distance of the locations of introduction of salts of TM and of alkali metal hydroxide is equal or less than 6 times the hydraulic diameter of the tip of the inlet pipe of the alkali metal hydroxide.
