The materials after graphitization are coated with resin materials twice. The solid phase particles are separated from the solvent by centrifugation and precipitation, then the particles are removed by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, and the particles are carbonized to obtain a high-rate carbon anode material. Granulation is the key process of artificial graphite processing, granulation is divided into pyrolysis process and ball milling screening process.
By using PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic method, the particles are coated and granulated twice to fill the inner shell of the material, so that the internal structure of the material is stable, and the carbon anode material has the advantages of high rate performance, high pressure compaction and high specific capacity. Difference: At present, there is little difference in particle size screening among various companies, mainly reflected in details and costs.
In the four processes of artificial graphite, crushing and screening are relatively simple, reflecting the technical threshold of negative PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field and the production level of enterprises are mainly two links: granulation and graphitization. And high-end artificial graphite, there will be more processes, such as secondary granulation, carbonization coating, secondary coating, doping modification and so on.
