Title: Qiyong Shi: Innovator in Battery-Grade Cobalt Tetroxide Preparation
Introduction
Qiyong Shi is a notable inventor based in Jiangsu, China. He has made significant contributions to the field of materials science, particularly in the preparation of battery-grade cobalt tetroxide. His innovative methods have the potential to enhance the efficiency of battery production.
Latest Patents
Qiyong Shi 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, 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 the battery-grade cobalt tetroxide that is significantly higher than that produced by prior art methods.
