TLDR
In this article, a process for the continuous preparation of such mixed metal hydroxides by precipitation of aluminium hydroxide in the presence of a nickel/cobalt mixed hydoxide in a tube reactor is described.Abstract:
Pulverulent mixed metal hydroxide comprising the metals nickel, cobalt and aluminium, wherein the powder particles have a core of nickel/cobalt hydroxide, the surface of which is coated with amorphous aluminium hydroxide. A process for the continuous preparation of such mixed metal hydroxides by precipitation of aluminium hydroxide in the presence of a nickel/cobalt mixed hydroxide in a tube reactor. Use of the mixed metal hydroxides for the preparation of active materials for positive electrodes of a secondary battery.read more
