What is Artificial graphite ?
According to statistics from China Chemical and Physical Power Supply Industry Association， China's export volume and export value of lithium-ion batteries have continued to increase. In 2021, China's exports of lithium-ion batteries were 3.428 billion, with a year-on-year growth of 54.34%. The export of lithium-ion batteries was 28.428 billion DOLLARS, up 78.34% year on year.
From the battery export destination, so far. China's lithium-ion batteries are mainly exported to the Asia Pacific and the United States and other places. In terms of price, the price of products exported to the United States is significantly higher than that in the Asia-Pacific region, mainly because the demand for lithium-ion batteries in the United States is higher than that in the Asia-Pacific region. In terms of export volume, the number of China's lithium-ion battery exports to Asian countries and regions far exceeds that of other countries. In 2021, The number of China's lithium-ion battery exports to Hong Kong, China is 675 million. 648 million were exported to Vietnam; 440 million were exported to India; 337 million were exported to the U.S. 222 million were exported to South Korea. The market for other Artificial graphite, led by lithium-ion batteries, is expected to expand globally.
In a broad sense, all graphite materials obtained by organic carbonization and then graphitization at high temperature can be called artificial graphite, such as carbon fiber, pyrolytic carbon, foamed graphite, etc. In the narrow sense, artificial graphite usually refers to the block solid material obtained through the processes of batching, kneading, molding, carbonization and graphitization, using carbonaceous raw materials with low impurity content as aggregates, coal tar pitch, etc. as binders. Such as graphite electrodes, isostatic graphite, etc.
What is Production method of Artificial graphite ?
There are many ways to manufacture artificial graphite. The common method is to use powdered high-quality calcined petroleum coke as the main raw material, add asphalt as a binder, and then add a small amount of other auxiliary materials. After the various raw materials are combined, they are pressed into shape, and then treated in a non-oxidizing atmosphere at 2500-3000 ° C to make them graphitized.
What is the main characteristics of Artificial graphite ?
Natural graphite: The crystal development is relatively complete, the degree of graphitization of flake graphite is more than 98%, and the degree of graphitization of natural microcrystalline graphite is usually below 93%.
Artificial graphite: The degree of crystal development depends on the raw material and the heat treatment temperature. Generally speaking, the higher the heat treatment temperature, the higher the degree of graphitization. The degree of graphitization of industrially produced artificial graphite is usually less than 90%.
Natural flake graphite: It is a single crystal with a relatively simple structure and only has crystallographic defects (such as point defects, dislocations, stacking faults, etc.), and exhibits anisotropic characteristics on the macroscopic level. The grains of natural microcrystalline graphite are small, the grains are disorderly arranged, and there are pores after removal of impurities, which shows isotropy on the macroscopic level.
Artificial graphite: It can be regarded as a multi-phase material, including graphite phase transformed from carbonaceous particles such as petroleum coke or pitch coke, graphite phase transformed from coal tar binder surrounding the particles, particle accumulation or coal tar pitch. The pores formed by the binder after heat treatment, etc.
physical form Natural graphite: usually exists in the form of powder and can be used alone, but it is usually used in combination with other materials.
Artificial graphite: There are many forms, including powder, fiber and block, while artificial graphite in the narrow sense is usually block, which needs to be processed into a certain shape when used.

Researchers at the University of Warwick in the UK have developed a lithium battery technology innovation. Adding graphene beams doubles battery life. By strengthening the structure of the anode with graphene beams, they have found an effective way to replace the graphite in the anode with silicon. Thereby increasing the capacity of the lithium-ion battery and more than doubling the lifespan.
