PURPOSE:To obtain nickel hydroxide with high utilization factor as an electrode active material together with shortening production-required hours, by performing generation of nickel hydroxide, with nickel salt and caustic alkali being added into an organic dispersion medium and made to react in a suspended state. CONSTITUTION:Nickel hydroxide is obtained to be used as a positive electrode active material by making nickel salt and caustic alkali to react in a suspended state, in an organic dispersion medium in which they are their reaction product, that is, nickel hydroxide, do not dissolve. When nickel salt and caustic alkali are added into an organic dispersion medium, in which they do not dissolve, and made to react in the suspended state, nickel hydroxide [Ni(OH)2] particles are prevented from gelling and the nickel hydroxide proceeds to react, with its particle property being kept. Because the nickel hydroxide produced by this reaction is prevented from gelling and can be easily broken, it is easy to produce it, having a large surface area and high utilization factor. |
