摘要:
A process for production of nickel oxyhydroxide by electrolytic oxidation of nickel hydroxide in the presence of an alkali metal halide. The nickel oxyhydroxide is produced by adding nickel hydroxide particles to an aqueous solution of an alkali metal halide and stirring the mixture to prepare a nickel hydroxide slurry, and then converting a portion of the nickel hydroxide to nickel oxyhydroxide by electrolytic oxidation in the presence of the alkali metal halide.
