| 1. A process for production of high density cobalt-manganese coprecipitated nickel hydroxide particles for use in lithium
ion batteries, wherein said particles are represented by the formula:
(Ni(1−x−y)CoxMny)(OH)2 wherein 1/10≤x≤⅓ and 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, 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.
