ABSTRACT:
A manufacturing process for nickel (II) hydroxide suitable as active positive electrode material in alkaline electrochemical cells transforms solid Ni(NO.sub.3).sub.2 directly into Ni(OH).sub.2 using sodium hydroxide and with the least possible homogeneous solute phase of Ni.sup.2+ ions. Ni(NO.sub.3).sub.2 is deposited on the lower end of a diagonally upward moving conveyor belt, to which concentrated NaOH is supplied from the opposite direction. The depressions in the conveyor belt, which prevent downward sliding of the reaction product, discharge at the upper end Ni(OH).sub.2, together with easily separable NaNO.sub.3. At the lower end, the used NaOH is discharged. It can be reconcentrated, after separation of entrained NaNO.sub.3, in a vacuum evaporator and reused. The intermediate products of the process are basic nickel nitrates, for example of the composition Ni(NO.sub.3).sub.2 .times.Ni(OH).sub.2 .times.6H.sub.2 O.
