As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings. As an anti-corrosion material, it is a rust resistant primer made of carbon black, talc powder, and oil, which has good chemical resistance and solvent corrosion resistance. If chemical pigments such as zinc yellow are added to the formula, the rust prevention effect will be better.

The manufacturer of flake graphite believes that expandable graphite is a Graphite intercalation compound made from natural graphite flakes through chemical or electrochemical treatment. Under heating conditions, the volume of expandable graphite rapidly expands (up to 300 times), suffocating the flame and producing expanding substances that can isolate the flame, delay or interrupt its spread, be non combustible, have good flexibility, high surface energy, and good carbonization layer strength. However, the volume and dosage of the expansion body should be appropriately selected. The experiment shows that a particle size of 150 m, an expansion rate of 30%, and a dosage of 5% are more suitable. Graphite can be directly used as carbon conductive filler or made into composite conductive filler for conductive coatings. However, due to the large number of graphite flakes, the performance of the coating becomes fragile, and its application is limited. To this end, measures are taken to further improve the conductivity of graphite and effectively reduce the amount of graphite sheets added.

The manufacturer of flake graphite believes that solvent-free thick film conductive coatings use short cut fiber materials with good deformation resistance and cracking resistance as functional fillers. This coating has the characteristics of corrosion resistance, low residual stress during curing, good resistance to matrix deformation and cracking, stable construction performance, and long-term electrostatic conductivity. It can be used to guide the electrostatic coating of the inner wall of crude oil storage tanks. Data shows that by using chemical plating technology to coat graphite powder with metals such as copper, nickel, and silver, a composite conductive filler is prepared. It is used in conductive coatings at a dosage of 30%, which not only has good conductivity but also further improves corrosion resistance.

In lithium-ion battery materials, the negative electrode material is the key to determining battery performance. As a high crystallinity graphite material, the particle size of flake graphite directly affects the specific surface area of the electrode and the ratio of edge carbon atoms, and has a significant impact on the irreversible specific capacity of charging. Therefore, flake graphite plays a crucial role in batteries.

1. Flake graphite has advantages such as high electronic conductivity, large lithium ion diffusion coefficient, high embedding capacity, and low embedding potential, making it one of the important materials for lithium batteries.

2. Scale graphite can stabilize the voltage of lithium batteries, reduce their internal resistance, and prolong their storage time. Increase battery life.

3. Scale graphite can reduce the amount of flake graphite powder used in lithium batteries, greatly reducing the cost of the battery.
