The physical and chemical characteristics of cathode materials determine the difficulty and method of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal. Graphite anode materials have good electrical conductivity and layered structure. In the screening process, iron impurities may be embedded between layers or adsorbed on the surface. The difference in the particle size, shape and surface properties of artificial graphite and natural graphite will affect the effect of iron removal sieve.
The production process of artificial graphite includes several steps, such as pretreatment, granulation, graphitization and ball grinding sieve. In these processes, iron impurities may be introduced, and the material status of different steps is different, and the focus of iron removal sieve is also different. Adding iron into the cathode material of lithium batteries is a problem to be solved. The PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron sieve technique is designed to remove iron impurities from the cathode material efficiently and ensuring that the quality of the cathode material is not affected.
In the pretreatment stage, the initial purity of raw material will affect the subsequent PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal workload; the particle aggregation state of the material after granulation may wrap the iron impurities and increase the difficulty of iron removal; the material structure change after graphitization may also affect the presence and removal of iron impurities.
