| titleOfInvention | Coated nickel hydroxide powder for positive electrode active material of alkaline secondary battery and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a coating suitable for a positive electrode active material of an alkaline secondary battery by ensuring uniformity and adhesion when forming a coating mainly composed of cobalt oxyhydroxide on the particle surface of nickel hydroxide powder. Nickel hydroxide powder is provided. A suspension width of nickel hydroxide powder is maintained at a pH of 8 to 11.5, and a supply width d of a cobalt salt aqueous solution in a direction perpendicular to the flow direction of the suspension at the contact portion and the suspension. The ratio ρ / (d × v) of the supply rate ρ of the cobalt salt aqueous solution to the product of the flow velocity v is controlled to 3.5 × 10 −4 mol / cm 2 or less to supply the cobalt salt aqueous solution and the alkaline aqueous solution, The surface of the nickel oxide particles is coated with cobalt hydroxide. Thereafter, the pH of the slurry of the cobalt hydroxide-coated nickel hydroxide powder is set to 12.5 or more, and oxygen is supplied so that the total amount of oxygen supply is 30 l / mol or more with respect to the molar amount of cobalt in the coating. Oxidizes cobalt hydroxide. [Selection] Figure 1 |
