Who is the potential one? Artificial Graphite VS Natural Graphite

Natural graphite is derived from mines, mined from mines and made through flotation, spheroidization, and surface coating; artificial graphite is derived from coal and petrochemical by-products, and is based on coal tar pitch or residual oil, a by-product of petroleum or coal chemical industry. The raw material is made into needle coke by delayed coking, granulated and graphitized.

As the sales of new energy vehicles and power batteries continue to grow, the demand for anode materials is still strong, and the anode materials are mainly artificial graphite and natural graphite. Among them, artificial graphite accounts for more than 80%, so who has more potential between natural graphite and artificial graphite?

Artificial graphite VS Natural graphite

(1) Natural graphite particles vary in size and have a wide particle size distribution. The mined natural graphite ore needs to go through steps such as flotation, spheroidization, and surface coating to make natural graphite anode materials. more consistent.

(2) Natural graphite has high capacity, high compaction density, and relatively cheap price, but due to different particle sizes, more surface defects, poor compatibility with electrolyte, and more side reactions; while artificial graphite has various properties It is more balanced, has good cycle performance, and has better compatibility with the electrolyte, so the price will be more expensive.

(3) Although natural graphite has cost and specific capacity advantages, its cycle life is low and its consistency is lower than that of artificial graphite. Compared with natural modified graphite, domestic artificial graphite technology is relatively mature.

(4) Natural graphite is mainly used in small lithium batteries and lithium batteries for general-purpose electronic products, while artificial graphite is widely used in automotive power batteries and medium- The field of high-end electronic products. At present, with the continuous expansion of the power battery market, the comprehensive requirements for factors such as material cost, processing performance, energy density, cycle life, and fast charging rate have increased, helping artificial graphite to become the most important material in my country’s anode materials.

(5) There is no clear distinction between artificial graphite and natural graphite technology routes, and more is based on the choice of one’s own technical route. The structure of natural graphite determines that the volume of graphite will change greatly during the lithium intercalation and deintercalation process, resulting in the destruction of the graphite layer structure, resulting in a large irreversible capacity loss and severe deterioration of cycle performance. Therefore, when natural graphite is used, it often focuses on its modification research to improve its own structural shortcomings and improve battery performance.

Affected by the application of new energy vehicles, the proportion of artificial graphite will continue to rise. Due to the excellent characteristics of natural graphite, such as expandable graphite, artificial graphite cannot replace natural graphite; and the current composite graphite route of artificial graphite doped with natural graphite also gradually increases the demand for natural graphite. In the future economic development, natural graphite still has its own advantages. replaced market. Franli’s factory is also gradually upgrading its technology to produce artificial graphite to produce better quality graphite materials.
