As a key material for lithium-ion batteries, graphite negative electrode materials have gradually become the mainstream of the negative electrode materials market, accounting for about 70% of the market share. The graphitization process of the artificial graphite anode MATERIAL is the key point affecting the quality of the anode material and the technical difficulty, the mainstream process and key technical points of the graphite PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal process talk about our experience and understanding, It is hoped to play a certain role in the production of graphitization of artificial graphite anode materials.
Graphite PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal process is to make full use of resistance heat to heat the carbon material to 2300~3 000 ℃, so that the amorphous chaotic layer structure of carbon into an ordered stone ink crystal structure process. The energy of crystal structure transformation and atomic rearrangement comes from high temperature heat treatment. With the increase of heat treatment temperature, the graphite layer spacing gradually decreases.
Generally between 0.343 and 0.346 nm, the general temperature changes significantly when it reaches 2 500 ° C, and gradually changes slowly when it reaches 3000 ° C until the entire graphite PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal process is completed. The artificial graphite anode material is successfully converted from carbon structure to graphite structure through graphitization and high temperature treatment, and has the corresponding function of the negative electrode of lithium batteries.
