Benefits of Artificial Graphite

Storage Capability

Artificial graphite’s layered structure allows lithium batteries to intercalate (slide between layers). This means that lithium ions from the battery’s cathode move to the graphite anode and nestle between its layers when the battery charges. During discharge, these ions move back to the cathode, releasing energy in the process.

Stability

Graphite ensures the battery remains stable during charge and discharge cycles. Its structural stability helps maintain the lithium batteries’ integrity, enabling longer battery life.

Volume

Graphite is a relatively light material (compared to components like nickel and cobalt), but still accounts for 10-20% of a battery by weight because of how much of it is used in anode material.

Manufacturing Process of Artificial Graphite

Raw material mixing

We select petroleum coke, needle coke, etc. which have high purity and good crystallinity as aggregates. Then mix them with binders such as coal, tar, pitch, etc. in a certain proportion and knead in the kneading equipment at a temperature of 150 – 200°C. In this way, the binder is evenly wrapped on the surface of the aggregate particles, forming a plastic paste. Typically, we define pitch as a binder for synthetic graphite.

Molding

Compression molding: We put the paste into the mold and apply a pressure of 10 – 50MPa to make the paste form into the desired shape in the mold, such as block, plate, etc.
Extrusion molding: For products such as electrodes, we extrude the paste through the mold of an extruder to form a cylindrical or other specific shape of green body.

Heat treatment

Carbonization: We put the shaped green billet into the carbonization furnace. Then, heat it to 800 – 1000°C at a heating rate of 1 – 5 °C/min under the protection of inert gases such as nitrogen or argon. In this process, the non-carbon elements in the binder escape in the form of a gas, and the remaining carbon further binds the aggregate particles.
Graphitization: Then place the carbonized body in a graphitization furnace and heat it to 2500 – 3000°C at a heating rate of 5 – 10 °C/min. At this high temperature, the carbon atoms rearrange and the crystal structure gradually shifts to a graphite structure.

Application of Artificial Graphite

Battery industry
Artificial graphite anodes have high theoretical specific capacity, good cycling stability and low lithium intercalation potential. They are widely used in various lithium-ion battery products, which play a vital role in improving the overall performance of batteries. In addition, graphite is used to electrolyze the cathode of electrolytic cells for magnesium, aluminum, etc.

Steelmaking and metallurgical industry
You can use graphite as a carburant in the steelmaking industry. In the electric arc furnace steelmaking process, the graphite electrode acts as a conductive electrode to transmit electrical energy to the furnace, creating an electric arc that melts the charge. It has good electrical conductivity, high temperature resistance and chemical stability.

Friction Materials
Graphite is used in the manufacture of clutches in mechanical transmission systems, brake pads in automobiles, and high-temperature lubricant friction materials. For example, the lubricity and heat resistance of artificial graphite powder can reduce the coefficient of friction, reduce wear. Thereby improving the service life and performance of friction materials. This ensure the normal operation of braking and transmission systems of automobiles, trains and other vehicles.

Heat Dissipation and Lighting Materials
In power electronics such as power transistors, rectifiers, inverters, etc., you will use artificial graphite sheet to dissipate heat. These devices generate a lot of heat when they are working. Therefor, and good heat dissipation helps to improve the reliability and efficiency of the equipment. Meanwhile, it reduces failures and performance degradation caused by overheating.

Aerospace and defense industries
With a high melting point, strong resistance to thermal shock, and corrosion resistance. It can be used as nuclear fuel and as a cladding material in high-temperature gas-cooled reactors. In addition, graphite is also used to manufacture nozzles for space rockets, aerospace engine parts, and thermal insulation structural materials.

FAQ

Q: Can graphite be made artificially?

A: Artificial graphite is fabricated by heat treatment of petroleum coke, coal-tar pitch, or oil. Specific capacity and reversibility is lost at high temperatures from 1000 Ah kg−1 (at 500°C) to 150 Ah kg−1 (1800°C).

Q: What is the difference between natural and artificial graphite?

A: Natural graphite anode has the advantages of lower cost, high capacity and lower energy consumption compared with the corresponding synthetic anode. But the latter performs much better in electrolyte compatibility, fast-charge turnaround and battery longevity.

Q: What are the three types of graphite?

A: The three forms are amorphous graphite, flake graphite and crystalline vein graphite, and they each have unique properties that make them well-suited for certain applications.

Q: How is graphite made from coke?

A: The raw materials for synthetic graphite fabrication like petroleum coke, pitch coke, carbon black, and natural graphite are ground in crushers and ball mills. The resulting powder is screened based on the desired particle size. Binders are then used to finish the powder preparation process.
