Preparation method for 2-4 micrometers battery-grade cobalt tetroxide |
| abstract |
The present invention discloses a preparation method for 2-4 μm battery-grade cobalt tetroxide, comprises following steps: 1) adding a cobalt salt solution and an alkaline solution by parallel flows to a reactor with a base solution and an air flow, controlling pH value of a system by adjusting flow rate of the alkaline solution for coprecipitation reaction at a certain stirring rate, decreasing the pH value of the reaction system and increasing flow rate of the cobalt salt solution after the reaction solutions begin to overflow; 2) aging and drying the cobalt oxyhydroxide slurry in sequence; 3) calcining the dried cobalt oxyhydroxide. By adopting this method, tap density of the battery-grade cobalt tetroxide obtained is much higher than that of cobalt tetroxide with a same particle size specification prepared by the prior art. |
