| titleOfInvention | Coated nickel hydroxide powder for positive electrode active material for alkaline secondary battery, and production method therefor |
| abstract | Provided is a coated nickel hydroxide powder that is obtained by forming a coating mainly containing cobalt oxyhydroxide on the surface of particles of a nickel hydroxide powder so that the uniformity and adhesion properties of the coating are ensured, and is therefore suitable for a positive electrode active material of alkaline secondary battery. n The pH of a suspension of a nickel hydroxide powder is kept at 8 to 11.5, and an aqueous cobalt salt solution and an aqueous alkali solution are supplied to the suspension while the ratio of the supply rate ρ of the aqueous cobalt salt solution to the product of the supply width d of the aqueous cobalt salt solution in a direction orthogonal to the flow direction of the suspension and the flow velocity v of the suspension in a contact portion between the suspension and the aqueous cobalt salt solution, that is, ρ/(d×v) is controlled to be 3.5×10 −4 mol/cm 2 or less to coat the surface of nickel hydroxide particles with cobalt hydroxide. Then, the pH of a slurry of the cobalt-hydroxide-coated nickel hydroxide powder is adjusted to 12.5 or higher, and oxygen is supplied to the slurry so that the total amount of oxygen supplied per mole of cobalt in the coating is 30 l/mol or more to oxidize cobalt hydroxide. |
