The latest forecast from consulting firm AlixPartners is that the chip shortage may cost the global auto industry $110 billion; it will reduce global auto production by 3.9 million this year. For the global chip shortage, AlixPartners analyzed that the main reason is that the chip production cycle is too long; at the same time, other uncontrollable risks from the industry chain have also affected the production rhythm. As the chip supply shortage continues to intensify, some automakers' factories have been forced to stop production for several days Even weeks, which companies such as Ford, GM, Stellantis, and others have been hit particularly hard. Even BMW, which was previously less affected, is beginning to show difficulties, with its Oxford plant in the UK shutting down for three days from April 30 and its Regensburg plant in Germany starting to reduce production shifts this week.
Chip supply shortages drive Artificial graphite.
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 ?
Crystal structure
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%.
organizational structure
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.

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the Artificial graphite would keep being influenced by the high energy prices.
