Preparation method of flaky cobalt powder

The invention discloses a preparation method of flaky cobalt powder. The preparation method comprises the steps that water, cobalt salt, a complexing agent, a cobalt plating brightening agent, a dispersing agent, an anti-oxidant, acid, a flaky acid compound crystallization template or a sublimable flaky compound crystallization template, a reducing agent and a surfactant serve as raw materials, achemical plating method is adopted, cobalt is plated on the surface of the flaky compound crystallization template until cobalt ions completely react, and after a reaction is completed, through separation purification and processing treatment technological processes, the flaky cobalt powder is directly obtained without ball milling. According to the technical scheme, the preparation method has theseries of advantages that energy consumption is low, environmental pollution is small, the production technology is simple, the technology route is short, investment in large-scale production equipment is small, the productio
