There are many kinds of artificial graphite and different production processes. In a broad sense, all graphite materials obtained by carbonization of organic matters and treated by high temperature after being treated with graphite can be collectively referred to as artificial graphite.In the narrow sense, artificial graphite usually refers to the massive solid materials prepared by batching.

    Artificial graphite and natural graphite are similar in structure and similar in physical properties, but the use is very different. Distinguish the role of artificial graphite and natural graphite, avoid the mistake of factory decision-making, and avoid bringing very large resource consumption and economic loss. From the perspective of the structural composition, characteristics and application of artificial graphite and natural graphite, Franli Factory distinguishes the characteristics between the two, and understands the important connections and application progress.


    Features of artificial graphite

    Artificial graphite is similar to polycrystals in crystallography. There are many types of artificial graphite, and the production process is very different. Broadly speaking, any graphite material obtained by carbonization of organic compounds and then treated by graphitization at high temperature can be collectively referred to as synthetic graphite, such as graphite chemical fibers, pyrolytic graphite, foam graphite, etc. In the narrow sense, artificial graphite generally refers to a block solid material prepared by using graphite raw materials with low residue content (petroleum coke, asphalt coke, etc.) as aggregates, asphalt glue, etc. as binders, and through batching, mixing, molding, carbonization (called roasting in industrial production) and graphitization, such as graphite electrodes, hot isostatic pressed graphite, etc.

    Graphite performance difference

    Graphite is a unique form of carbon that has several outstanding properties that make it ideal for use in a wide range of applications. Different type of graphite include:

    (1) The main raw material of artificial graphite is powdered calcined petroleum coke, in which asphalt is added as a binder, and a small amount of other excipients are added. After the various raw materials are combined, they are pressed into shape, and then processed in a non-oxidizing atmosphere of 2500 ~ 3000 ° C to graphitize them.

    Artificial Graphite

    (2) The purity of natural graphite is often expressed as carbon content or ash, generally the higher the carbon content, the less ash, the higher the price. Particle size is often used in imperial to represent the average particle size of the product. For the regular number, the larger the particle size, the higher the price; For negative numbers, the smaller the particle size, the more valuable it is.

    (3) The capacity of natural graphite is high, the compaction density is high, and the price is relatively cheap, but due to the different particle sizes, there are more surface defects, the compatibility with the electrolyte is relatively poor, and the side reactions are more; The properties of artificial graphite are more balanced, the cycle performance is good, and the compatibility with the electrolyte is also better, so the price will be more expensive.

    (4) Although natural graphite has cost and specific capacity advantages, its cycle life is low, and the consistency is lower than that of artificial graphite, compared with natural modified graphite, artificial graphite technology development is more mature, and its electrolyte compatibility is better.

    Artificial graphite can now be used as an auxiliary raw material for fuel cells, lithium-ion batteries and other high-efficiency energy parts, and has broad market prospects. Previously, some countries used natural graphite as a raw material, and the anode material used for lithium-ion batteries replaced the expensive artificial graphite. Now our Franli factory in order to protect non-renewable natural graphite, the use of artificial graphite development to adapt to the production of lithium-ion battery anode materials, that is, spherical graphite modified products, Franli factory artificial graphite dedicated to lithium-ion battery industry chain, driving the future development of new energy industry, there is a need to contact us.
