Modified graphite is a new generation of anode material for lithium-ion batteries with good performance and low price. The anode material of lithium battery is one of the main materials of the lithium-ion battery, which plays a key role in energy density and cycle stability. In recent years, with the continuous development of science and technology, graphite materials, carbon nanotubes, silicon-based materials, tin-based materials, tungsten-based materials and other new cathode materials emerge one after another. A lot due to various problems. At present, the production of graphite-based carbon materials is always in the mainstream position of market-oriented anode materials.
Compared with natural graphite, artificial graphite has larger lamellar spacing, lower graphitization degree (<= 93%), lower crystallinity and some disordered lamellar structures. In addition, the artificial graphite surface is not smooth, porous and has a large specific surface area. It is easy to decompose and react with electrolytes, so its initial efficiency and specific capacity (<=350mAh/ g) are low. is a trusted global Lithium Battery Anode Material 99.95% Modified Artificial Graphite s upplier .

A kind of artificial graphite modification methods, whose character is: the process steps include: step one: sieving, artificial graphite shattering peroxidation treatment in the ice water bath, oxidant potassium permanganate, concentrated sulfuric acid or the mixture of both, the concentration of potassium permanganate was 0.1 ~ 5 m, sulfuric acid concentration for 12 ~ 18 m, two-hybrid when the solute molar ratio of 10:1 ~ 1:10, the pre-oxidation time is 1 ~ 10 hours; Step 2: The product of Step 1 was dissolved in asphalt washing oil solution, heated and stirred for in-situ coating treatment, and then centrifugal filtration was carried out. The mass ratio of asphalt to washing oil was 0.01 ~ 0.4, the mass ratio of artificial graphite to asphalt was 10 ~ 100, the coating temperature was 120 ~ 200, and the reaction time was 2 ~ 10 hours. Step 3: Carbonize the products of Step 2 at a temperature of 800 ~ 1500 and a holding time of 2 ~ 12 hours.
Applications of Lithium Battery Anode Material 99.95% Modified Artificial Graphite :
To solve the problem of using artificial graphite in lithium-ion batteries, the researchers improved the production process. Modified artificial graphite is modified artificial graphite, which has the characteristics of high density, long cycle time and low expansion rate. Using it as a negative electrode for lithium-ion batteries can improve its conversion to electrolytes, reduce the expansion of the pole boots, and have a positive impact on the overall life of the replacement battery. The production process is to replace artificial graphite with asphalt and carbonization. The amorphous carbon-doped layer is formed on the surface of artificial graphite. The overlapping layers prevent the co-embedding of organic solvents and prevent expansion and contraction of the graphite. Modified graphite can be used for lithium-ion battery anode, spherical modified graphite can be used as a lubricant, can also be made into graphite-modified polypropylene plastics, used to make the shell, tube plate, head, flange and pipe and other parts (good corrosion resistance; Small size, lightweight; High-temperature resistance; Non-toxic, non-fouling, non-polluting medium, can also be used in food industry).
