Abstract
The present disclosure belongs to the technical field of metal oxide materials, and discloses a synthesis method of cobalt hydroxide and cobalt hydroxide. The synthesis method includes: (1) stirring and heating ammonium citrate, introducing a protective gas, adding a cobalt salt and a mixed alkali liquor to allow a reaction, and adjusting a pH to obtain a cobalt hydroxide slurry; and (2) subjecting the cobalt hydroxide slurry to alkali-leaching, filtering, and slurrying a resulting filter residue; and washing a resulting slurry with a detergent, and drying the resulting slurry to obtain the cobalt hydroxide. In the present disclosure, ammonium citrate is used as a base solution, and a cobalt solution and a mixed alkali liquor are added to synthesize a cobalt hydroxide slurry in one step under a protective atmosphere.
