Abstract
The process precipitates additives onto nickel hydroxide seeds in an ammonia solution. Then introducing at least one metallic additive into the aqueous solution creates a slurry having a reducing potential. The additive is selected from the group consisting of aluminum, cadmium, cobalt, indium, iron, manganese and zinc. Introducing oxygen into the additive-containing slurry at a controlled rate maintains the reducing potential of the solution. At least one of the additives dissolves into the aqueous solution in excess of the slurry's solution solubility to precipitate the additive in the form of a hydroxide on the nickel hydroxide seeds.
