Latest Patents
Fan Bi holds a patent for the "Preparation method for 2-4 micrometers battery-grade cobalt tetroxide." This invention outlines a method that includes several steps: first, adding a cobalt salt solution and an alkaline solution in parallel flows to a reactor containing a base solution and an air flow. The pH value of the system is controlled by adjusting the flow rate of the alkaline solution for a coprecipitation reaction at a specific stirring rate. After the reaction solutions begin to overflow, the pH value is decreased, and the flow rate of the cobalt salt solution is increased. The process continues with aging and drying the cobalt oxyhydroxide slurry, followed by calcining the dried cobalt oxyhydroxide. This method results in a tap density of battery-grade cobalt tetroxide that is significantly higher than that produced by prior art methods.
