First, the permanent magnet PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC was used to initially remove iron from the new silicon matrix composite cathode material and remove the iron impurities of the larger particles. Then, the electromagnetic iron remover is used to remove iron, and the magnetic field strength of the electromagnetic iron remover is accurately adjusted according to the characteristics of the material and the residual situation of iron impurities.
In the process of iron removal, close attention is paid to the physical and chemical changes of the material, such as the particle morphology of the material by scanning electron microscope, and the electrochemical test of the material. After the combined PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal process, the content of iron impurities in the new silicon matrix composite cathode material is greatly reduced.
It is found that the iron removal process has little influence on the physical and chemical properties of the material, and the high specific capacity of the material and the good cycling performance are maintained. This shows that the combined PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal process has a good effect for this new cathode material sensitive to iron impurities, which lays a good foundation for its subsequent application and development.
