Raw Material: Green Petroleum Coke, Green Needle Coke and High soft point pitch
We can provide the complete solution for high temperature carbonization treatment system by working together with the top supplier of roller hearth kiln supplier from China and Japan. During the high temperature condition (1200 degree) by electricity, it make the coating material and spherical graphite fused together and the coating material formed a shell to wrapping the spherical graphite. The roller hearth kiln is the best solution for large scale carbonization processing.
Kiln Length: Max. 60 m
Kiln Width: Max. 2 m
Anode materials calcination for lithium batteries: green petroleum coke (GPC coke), green needle coke, calcined petroleum coke (CPC coke), calcined needle coke, coating pitch, natural graphite, and synthetic graphite.
Cathode material sintering for lithium batteries: LiCoO (lithium cobalt oxide), NCM( lithium nickel manganese cobalt), LMO (lithium manganese oxide), LFP (lithium iron phosphate) and NCA (Lithium nickel aluminum cobalt) .
Carbonization treatment before graphitization process can not only avoid excessive temperature during the graphitization process, but also accelerate the thermal decomposition and thermal polycondensation process of asphalt.
Lithium iron phosphate cathode materials are mainly synthesized from the precursors iron phosphate and lithium carbonate through high-temperature solid-state reaction.
Natural graphite anode materials are mainly used in the 3C field, while artificial graphite anode materials are mainly used in EV field.
After adding the carbonization process, the specific surface area was reduced, and the rate performance of the sample was increased.
The calcination temperature affect the lithium carbonate on the material surface and the pH value of the material, and has a certain impact on the tap density and specific surface area of the material.
Coke calcination is a process that involves the heating of green petroleum coke in order to remove volatile material and purify the coke for further processing.
After the carbonization process, the crystal structure of the graphite layers in the artificial graphite anode material becomes more ordered, which actually leads to an increase in the Coulomb efficiency and the capacity of the charge and discharge in the first cycle.
Carbonization refers to the calcination process below 1200°C, and graphitization refers to the high-temperature treatment process close to 3000°C.
