Raw Material: Green Petroleum Coke, Green Needle Coke and High soft point pitch
Our granulation reactor combines the coating and granulation processing functions together. It can make the coating pitch and graphite mixing evenly and sufficiently and the electrical heating device will provide staged heating to help the mixed materials coated. The complete granulation system contains weighing feeding device, high temperature reactor with electrical heating furnace, cooling jacketed reactor and waste gas receiver tank.
Reactor Volume: 200L-7000L/set
Capacity: 20-3000 kgs/day/set
Anode Material: green petroleum coke (GPC coke), green needle coke, calcined petroleum coke (CPC coke), calcined needle coke, coating pitch, natural graphite and carbon black.
Cathode material: LiCoO (lithium cobalt oxide), NCM( lithium nickel manganese cobalt), LMO (lithium manganese oxide), LFP (lithium iron phosphate).
The coating of petroleum coke refers to covering the surface of petroleum coke with a layer of material to improve the properties of petroleum coke. This coating material can be asphalt, resin, polymer, etc.
The common anode granulation process is to first mix coke and pitch by high-temperature melting, and then proceed through carbonization, graphitization, and other procedures in sequence.
LFP (LiFePO4) has the characteristics of high discharge power, fast charging and long cycle life, with a theoretical capacity of 170mAh/g.
Carbon coating on the needle coke surface followed by hydrogen reduction improves the electrochemical performance of the needle coke and enhances the first Coulombic efficiency and rate performance.
Natural graphite must be modified before it can be used as anode material. Commonly used modification methods include coating method, SEI film modification method, heteroatom doping, etc.
The complete system contains weighing feeding device, high temperature reactor with electrical heating furnace, cooling jacketed reactor and waste gas receiver tank.
The electrochemical performance of cathode materials also depends on their particle properties, such as morphology and microstructure， size distribution, tap density, specific surface area, and surface characteristics.
Taking the anode material as an example, the use of a battery anode formed by granulation can not only greatly improve the battery life, but also effectively increase the electric capacity.
