High density cobalt-manganese coprecipitated nickel hydroxide and process for its production

A process for production of high density cobalt-manganese coprecipitated nickel hydroxide particles represented by the formula:

• (Ni(1−x−y)CoxMny)(OH)2
• wherein {fraction (1/10)}≦x≦⅓ and {fraction (1/20)}≦y≦⅓;
• said process comprising the steps of:
• continuously supplying an aqueous solution of a nickel salt which contains a cobalt salt and a manganese salt of a complexing agent and an alkali metal hydroxide into a reactor either in an inert gas atmosphere or in the presence of a reducing agent;
• continuously growing crystals of said particles;
• and
• continuously removing crystals of said particles from said reactor.
