Naturalflake graphiteIt is a non-metallic mineral with unique physical and chemical properties such as high temperature resistance, oxidation resistance, corrosion resistance, thermal shock resistance, high strength, good toughness, high self-lubricating strength, strong thermal conductivity and electrical conductivity. Graphite series products are mainly used in metallurgy, machinery, electronics, batteries, chemical industry, light industry, military industry, national defense, aerospace, refractory materials and other industries. It is an indispensable non-metallic raw material for today's high technology.

The electrical conductivity of graphite is 100 times higher than that of general non-metallic minerals, and it is a conductive and antistatic material widely used in industry and life. What are the main applications of flake graphite?

1. Used in plastic or rubber, can be made into different conductive rubber and plastic products. The product has been widely used in anti-static additives, computer anti-electromagnetic screen, etc. In addition, it also has a wide range of applications in the fields of micro TV screens, mobile phones, solar cells, and light-emitting diodes.

2. Used in resins and coatings, it can be compounded with conductive polymers to make composite materials with excellent conductive properties. With its excellent conductivity, affordable price and simple operation, conductive graphite coating plays an irreplaceable role in household anti-static and anti-electromagnetic radiation in hospital buildings.

3. The use of conductive graphite powder in the ink can make the surface of the printed matter conductive and antistatic effect.

4. When used for conductive fiber and conductive cloth, the product can shield electromagnetic waves. Many of the radiation suits we usually see use this principle.

As a key material for lithium-ion batteries, graphite anode materials have gradually become the mainstream of the anode materials market, accounting for about 70% of the market share. Since the development of lithium-ion batteries, a variety of cathode material systems have been derived, such as lithium cobalt oxide, lithium iron phosphate, nickel cobalt lithium manganate, nickel cobalt lithium aluminate, etc. But the graphite anode material system has been used until now.

Graphite anode materials are generally divided into natural graphite and artificial graphite. Natural graphite comes from mines, collected from Heilongjiang, Qingdao and other places, and is made by flotation, spheroidization and surface coating. Artificial graphite is derived from coal and petrochemical by-products. It is made of coal tar pitch or vacuum residue, a by-product of petroleum or coal chemical industry, through delayed coking into needle coke, and then pelletized and graphitized.

Natural graphite can be divided into flake graphite and earthy graphite. The anode material is usually flake graphite, which has the advantages of large reserves, low cost, low potential and stable curve. In a suitable electrolyte, the coulombic efficiency of the first cycle is 90% ~ 93%, and the reversible capacity can reach 340~370 mAhg-1. It is one of the mainstream anode materials for lithium-ion batteries.

The above are some knowledge points about flake graphite. I hope you can seriously study and understand the relevant knowledge, choose the products and equipment suitable for your needs, and ensure your own benefits.
