The solvent was used for surface treatment, and the solid particles were separated from the solvent by centrifugation and precipitation, and then the particles of 5-20um were carbonized to obtain a high rate carbon anode material. Using this PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC method by mixing and fabricating particles, the particles are coated twice and the inner shell of the MATERIAL is filled, so that the internal structure of the MATERIAL is stable, so that the carbon anode MATERIAL has the advantages of high rate performance, high pressure solid, high specific capacity and so on.
Among the four processes of synthetic graphite, crushing and screening are relatively simple. The main steps reflecting the technical threshold of negative electrode industry and the production level of enterprises are granulation and graphitization. For high-end artificial graphite, there will be more PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC processes, such as secondary granulation, carbonization coating, secondary coating, doping modification, etc.
Difference: pretreatment grinding powder is divided into mechanical grinding powder and air grinding powder, and the mainstream is air grinding powder. There are many kinds of adhesives, generally petroleum asphalt, coal asphalt, phenolic resin or epoxy resin. Pretreatment is not the key link, the main is PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC screening to obtain the required size of precursor, and as far as possible to obtain homogeneous particles to reduce the expansion coefficient.
