Title: Chao Ning: Innovator in Battery-Grade Cobalt Tetroxide Production
Introduction
Chao Ning is a prominent inventor based in Jiangsu, China. He has made significant contributions to the field of materials science, particularly in the production of battery-grade cobalt tetroxide. His innovative methods have the potential to enhance the efficiency and quality of battery materials.
Latest Patents
Chao Ning holds a patent for a preparation method for 2-4 micrometers battery-grade cobalt tetroxide. The patent outlines a process that includes several key steps: first, a cobalt salt solution and an alkaline solution are added 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 to facilitate a coprecipitation reaction. 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.
