Manufacturing method of active materials for the positive electrode in alkaline storage batteries |
| abstract |
A process for producing positive electrode active material includes feeding an aqueous nickel salt solution, aqueous solutions of different kinds of metals, aqueous solution containing ammonium ions and aqueous alkali solution each independently and simultaneously into a reaction vessel such that the amount of alkali metal is 1.9-2.3 moles relative to 1 mole of the total amount of nickel and different kinds of metals and the amount of ammonium ions is 2 moles or more relative to 1 mole of the total amount of nickel and different kinds of metals, the pH in the vessel is 11-13, the temperature in the vessel is 30-60 DEG C. and the average residence time is 20-50 hours. Further, in the process step of continuously growing the complex metal oxide particles from the salts of a plurality of metal elements through a plurality of successive reaction-deposition stages, the compositions and/or the kinds of the salts of metal element groups used for forming the oxide in the reaction-deposition stages adjacent to each other are made to be different from each other. |
