The Application of Natural Flake Graphite Powder

Natural flake graphite Natural crystalline graphite has a shape similar to fish phosphorus. It belongs to the hexagonal system and has layers. It exhibits good resistance to heat, electrical conductivity, heat conduction and lubrication.
Flake graphite can be found in complete crystals or thin flakes. It has good physical and chemical properties and excellent thermal conductivity.

Natural Flake Graphite Application

Refractory
Flake graphite is used widely in advanced refractories in the metalurgical industry. Magnesia carbon bricks, crucibles and others. Stabilizers in the military industry for pyrotechnics, desulfurization accelerators, pencil leads, and carbon brushes for industry.

Graphite Emulsion can be made from flake graphite after it has been processed. It can be used in lubricants and mold release agents, wire-drawing agents, conductive coatings, and other applications. Expanded graphite is also possible. This raw material can be used in flexible graphite products like flexible graphite seals, flexible graphite composites, and so on.

Coating
Flake graphite is used primarily as a functional filler for coatings.

Anti-corrosion material: The anti-rust primer is made of natural phosphorous flake Graphite and carbon Black, talcum Powder, and oil. It has good resistance to chemicals and solvents. Chemical pigments like zinc yellow can be added to the formulation to prevent rust.
Expandable graphite can be used as a fireproof material. This is a form of graphite interlaminar compound that has been produced by electrochemical or chemical treatment of natural graphiteflakes. Expandable graphite expands rapidly under heating (up to 300x), which suffocates a flame. It also generates expansions which can help isolate the flame or stop it from spreading. It is incombustible, flexible, strong, and has high surface energie.

Flake graphite may be used to make conductive coatings or as a carbon-based filler. Due to the large number of graphite flake added, the coating's performance and ease of application will be reduced. Therefore, we take measures to increase the conductivity of graphite as well as reduce the amount added graphite flakes.

This short-cut fiber material is a solvent-free thick films conductive coating with functional filleders. It has characteristics such as anti-corrosive medium penetration and low curing residue stress. It is also resistant to matrix deformation and cracking. The coating can be used for long-term static electricity transmission. The inner wall of crude oil storage tank's crude oil storage tanks can be coated with natural phosphorous flake graphite.
According to reports, electroless plating technology can be used to coat graphite dust with metals like nickel, silver, and copper. These fillers are used in conductive coated in an amount of 30 percent. It not only has good conductivity but also provides corrosion resistance.

The application status and development direction of graphite in lithium batteries

graphite: an ideal anode materials Natural graphite made from carbonaceous material organic origin under high temperatures It is a mixture of steel gray and black grey with semi-metallicluster. It is a hexagonal crystal structure. It features a hexagonal layered structure with high temperature resistance, heat conductivity and heat conduction. , Lubrication and plasticity.

Graphite is an older negative electrode material. Graphite is a more desirable negative electrode material than carbon materials. Its conductivity, crystallinity, and good layered structure are all better than those of other carbon materials.

Modifications: Optimize anode material performance

Graphite Negative Electrodes generally use natural flake graphite. But there are a few drawbacks.

(1) Flake graphite has a large surface area which has a greater influence on the first charge of the negative electrode and its discharge efficiency.
(2) The graphite layer structure determines that Li+ cannot penetrate the material's end and diffuse slowly into the particles. Flake graphite has an anisotropy that makes the Li+ diffusion path long and uneven. This causes a low specific ability.
(3) The graphite's layer spacing is too small. This increases Li+'s diffusion resistance, but also makes it less efficient at delivering high rates of charge. Li+ is easy for graphite to form lithium dendrites and deposit it on the graphite's surface. This can pose serious safety hazards.

Natural graphite can be modified to address these issues using technologies such as surface oxidation and surface fluorination. After taking into account cost and performance, industrial graphite modification is mainly done using carbon coating. Modified natural graphite is a commercially available material with a specific capacity between 340 and370 mA*h/g. This has a coulombic efficiency in excess of 93% in the first week. The DOD cycle time of over 1,000 times can also be used to supply small electronic products. Specific requirements for battery performance.

Innovation: Tap the Potential of Graphite Applications

People are continuously aiming to improve the performance of lithium-ion batteries with the rapid development in new energy vehicles and other industries. This results in a higher graphite-anode requirement.

Graphite concentrate is able to be further processed to make graphite products. These include graphene (spheroidized graphite), flexible graphite (fluorinated graphite), nuclear graphite or silicon-impregnated graphite), graphene (spheroidized graphite), expandable graphite(expheroidized graphite), flexible graphite (flexible graphite), fluorinated graphite and nuclear graphite) This will allow graphite to be used in lithium batteries at a higher level. Graphene is a good conductor and can help reduce volume expansion in electrode materials. This will greatly increase the power battery's performance. Graphene is commonly used in lithium-ion's negative and positive electrodes. Current collectors, separators and conductive additives are all examples of graphene. The future market opportunities are very broad, so it is the center of current research. Spherical graphite features good electrical conductivity and high crystallinity. It is used to replace negative electrode materials in the manufacture of lithium ion batteries at home as well as abroad.

Raw Materials and Processing Equipment of Spherical Graphite

Spherical graphite This graphite product is made with high-quality natural flake graphite. It also contains advanced processing technology that allows for graphite products to be produced with different levels of fineness and elliptical shape. Spherical graphite has the properties of high electrical conductivity and high crystallinity.
Spherical graphite The processing principle is: First, you need to pulverize natural flake graphite powder into small particles. Next, perform the de-angularization process, which will result in an ellipsoid, or spherical, shape. You can get the normal distribution for spherical graphite from the fine powder that is removed during this process.

Selection criteria spherical graphite, raw materials

The particle size of the spherical graphite material should be suitable. Too fine a particle size results in higher costs. A smaller particle size can affect the yield of spherical graphite. Additionally, adding too many products to the mix will increase the price of raw materials. Study have shown that it is easier to use spherical-graphite-making raw materials with a particle size between -100 and -100 mesh.

A very important aspect of spherical-graphite raw materials is their carbon content. The carbon content of spherical graphite raw materials is a key factor. The higher the carbon, the more expensive the raw materials. Additionally, the purification passes required to remove it will increase, increasing the equipment's wear and tear. Also, the overall cost of the equipment will rise. After practice and accumulation it contains 95%-96% of raw material, and the total cost is the lowest.

Selection criteria for spherical-graphite processing equipment

The airflow vortex-pulverizer is more used in the spherical processing. This has both the performance for pulverization as well as the ability to de-angularize. It is important to consider the quality of the equipment when selecting grading equipment.

Graphite anode material for lithium-ion batteries must be at least 99.95%. Purification is an essential part of the production process. Chemical purification is the most common method of producing high-purity, spherical graphite. Since the chemical raw materials used in the production process are strong acids, the purification equipment must be resistant to acid and corrosion. Chemical purification must be completed at a particular temperature. The equipment should also have a high resistance to heat.

After the chemical reactions, impurities found in the spherical graphite are dissolved into the reaction solution. They can then be washed. The most common washing equipment in this process is the filter press and centrifuge. The filter press offers many benefits, such as a higher recovery rate, low running material, low labor intensity and safety. However, it has a limited washing effect and can leave dead corners behind that cannot be washed. While the centrifuge offers more washing power and a more effective wash, it also has some drawbacks. Combining them works well.

The spherical Graphite after being washed is dried to remove moisture. It is also controlled below 0.5%. The most common problem with drying is secondary pollution. That is, when the spherical carbonite has been washed and dried, it becomes substandard because of the inclusion of impurities. This is mostly evident in the unqualified indicators about carbon content or trace elements. Drying equipment such as the drying kilns and dryers in microwave ovens is also used.

Is Graphite a Nanomaterial?

Graphite is a nanomaterial

Graphite is a soft, crystalline form of carbon (C). It occurs naturally in metamorphic rocks. It is a common allotrope of carbon and has properties of a metal and a nonmetal, exhibiting high thermal and electrical conductivity, inertness, and lubricity.

Synthetic graphite is produced from two raw materials: a carbon carrier, usually coal from crude oil, and pitch as a binder. It is then refined in a complex set of high-temperature processes to obtain desired properties.

It is also used in batteries and fuel cells, as an electrode for electrochemical cells, in brake linings, and foundry facings. It is a key component in lithium ion batteries.

In its natural state, graphite is grey to black in color and is opaque. It is lighter than diamond and smooth and slippery to the touch. It has a metallic luster and is highly refractory, chemically inert and heat stable at temperatures of 700 degC and above.

The atoms of carbon arrange themselves in the hexagonal pattern typically seen in diamond and other crystalline forms. The resulting hexagonal layered lattice makes graphite an excellent conductive material for electricity. Unlike diamond, graphite is a poor insulator.

As a result, it is very difficult to separate a single carbon atom from its lattice. This limiting property, along with its strength and flexibility, is what has made graphite so useful for so many applications. It is also a very durable material, which is why pencils and erasers are made from it.

An innovative application for nuclear-grade graphite are the ultra-high temperature reactor (UHTR), as well as the next generation nuclear power plants (NGNP).

What is graphite?
Graphite is a form of graphite, but it's only a powder. This retains all its primary and secondary characteristics.
Graphite, an allotrope for carbon, is called graphite. It is opaque solid and grayish-black. It can cause a paper to be greasy.
It is hardness is 1-2. With an increase in vertical impurities, the hardness will rise to 3-5. Its specific gravity ranges from 1.9 to2.3. The range of specific area is between 1-20m2/g. Under the condition of oxygen isolation, its melting point is above 3000, so it is one of the most temperature-resistant minerals. It can conduct heat and electricity.
Chemical stability, corrosion resistance. It is not easy to react against acid, alkali, or other agents. Graphite reacts with oxygen to produce carbon dioxide. Strong oxidants, such as potassium permanganate and concentrated nitric Acid, can oxidize graphite.
Natural graphite is not pure, so it often contains impurities, such as SiO2, Al2O3, FO, CaO and P2O5, or CuO. These impurities can often be found in the form quartz, pyrite or carbonate as well as other minerals. Water, asphalt, CO2, H2,CH4,N2 and other gases are also present. The analysis of graphite requires that, in addition to determining the fixed carbon content, volatile matter and Ash must be done simultaneously.

Is graphite dust toxic?
Excessive graphite exposure can cause respiratory problems. There have been reports of pulmonary fibrosis (a form of occupational lung disease) and pneumoconiosis (a type of pulmonary fibrosis). Workers' lung function and cardiovascular system may also be affected.

Modification of Natural Graphite and Artificial Graphite

The difference in processing technology and raw materials will determine the final product. graphite powder Natural graphite is separated from artificial graphite. Graphite is an ideal anode for lithium-ion batteries because of its low lithium cost and high efficiency.

Analyse of natural graphite

Natural flake graphite can be used to make natural graphite. It is then modified to produce spherical natural Graphite. Natural graphite has many disadvantages, even though it is popular.
Natural graphite exhibits many defects on the surface, large surface areas and low efficiency.

PC-based electrolyte can cause serious problems such as solvated lithium Ion co-embedding. This leads to graphite peeling and expansion, and ultimately, battery performance failure.

The anisotropy of natural graphite means that lithium ion is difficult to embed from the end faces. It also makes it easy for lithium ions to be precipitated. Natural graphite has a lot of problems. It is usually made from dense petroleum coke (or needle coke) as precursors.

Modifications to natural graphite

Different surfactants were applied to the graphite to fix its surface imperfections and toler electrolyte well.

To improve magnification of natural graphite, the first step is to modify the pore structure. After etching with strong alkali (KOH), the solution in an aqueous solution has been applied to the graphite.

You can also use strong oxidant solution to passivate surface active potential. This will increase natural graphite's efficiency.

Third, fluorinate natural graphite by using ClF3. Effectively, the cycle life and charge/discharge ratio are improved.

The amorphous graphite can also be coated to form "coreshell" structures. The carbon source for amorphous Carbon is typically pitch, phenolic or other low temperature pyrolytic material. Because of the long distance between carbon layers, the presence of carbon layer is able to isolate electrolyte from the particles. It can reduce surface active points, specific surface area and the isolation of direct contact. Enhance the intercalation or diffusion of lithiumion.

To solve the anisotropy problem in natural graphite, mechanical treatments are often employed to shape the particle morphology. An air flow shaping device uses wind to create particles that rub against each others and to cut corners. The method doesn't introduce any doping impurities. However, this will cause the pulverization to produce large quantities of particles at low yield.

Mechanical fusion machines use the material to spin at high speed inside the rotor. The material clings on to the wall using centrifugal force and then passes between the stator extrusionhead and the rotating rotor. This is when the material will be subject to extrusion force and shear pressure. To achieve the goal of spheroidization, the surface is subject to the friction between particles and other particles.

Natural graphite's particle sizes are reduced to 15-20 mm after the spheroidization process. The first efficiency and performance of the cycles is clearly improved. Magnification performances can also be greatly enhanced.

Modifications to Artificial Graphite

Modifications of artificial graphite. The modification process of artificial graphite has a different structure than that of natural graphite. The organization of particles can reduce graphite's OI value (position degree) generally. A needle coke precursor of 8-10mm in diameter is chosen. The carbon source for the binder is typically made from easily graphitized materials like asphalt. A number of needle coke particles can be bonded using drum furnace treatment. The secondary particles, with a size of 14-18mm, are then made into graphitization. This will help to reduce the Oi.
