Composition comprising lithium compound and mixed metal hydroxides and their preparation and use |
摘要 |
The present invention relates to a particulate mixed metal hydroxide that includes nickel, cobalt and aluminium. The powder particles have a core of nickel/cobalt hydroxide, and a surface that is coated with amorphous aluminium hydroxide. A process for the continuous preparation of such mixed metal hydroxides is also described. The process includes precipitating aluminium hydroxide in the presence of a nickel/cobalt mixed hydroxide in a tube reactor. The mixed metal hydroxides of the present invention may be used to prepare active materials for positive electrodes of a secondary battery.
