2023-06-20Since its inception, lithium-ion batteries have been widely used in multiple fields. At present, lithium-ion batteries are not only widely used in electronic products such as mobile phones, digital cameras, and tablets, but also in the application of car power supplies. Achieved certain breakthroughs; From the analysis of market economic demand for the future development of lithium-ion batteries, it can be seen that fast charging lithium-ion batteries will become an important research direction for lithium-ion batteries.In order to improve the fast charging performance of graphite negative electrode materials for batteries, a series of graphite negative electrode materials made of different coke materials were prepared through experiments. And particle size, polarization, and XRD tests were conducted, resulting in a lithium ion battery charge rate and charge rate. Loop testing and analysis of test results.Analysis of the fast charging mechanism of lithium-ion power batteries and the i
2023-06-20High purity flake graphite has good high-temperature resistance, conductivity, thermal conductivity, lubricity, and chemical stability. Graphite powder manufacturers are widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, fire protection, electronics, medicine, military industry, aerospace, etc. It plays an increasingly important role in the national economy and is an indispensable non-metallic raw material for modern industrial and high-tech development. Trace impurities have a significant impact on the performance of graphite products. The higher the carbon content of high-purity flake graphite, the better its performance as a functional material.In order to analyze trace impurities in high-purity flake graphite, the sample is usually ashed or wet digested to remove carbon, the ash is dissolved in acid, and the impurity content in the solution is then determined. The ashing method does not require the use of ultrapure acids to dissolve a
2023-06-20As 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 appropriate
2023-06-19Flake graphite is a natural graphite ore, similar in shape to fish scales, and is a hexagonal crystal with a layered structure. Now this product has good acid and alkali resistance, high temperature resistance, conductivity, thermal conductivity, and lubrication performance. Now widely used as refractory materials and coatings in the smelting industry. Such as magnesia carbon bricks, crucibles and other military pyrotechnic stabilizers, desulfurization accelerators in the smelting industry, pencil lead, carbon brushes in the electrical industry, electrodes in batteries, catalysts in the chemical industry, etc. Lubricants, release agents, wire drawing agents, conductive coatings, etc. Scale graphite has a lubricating effect, so it can play a lubricating role in the lock cylinder, making the door easy to open. Flake graphite also has characteristics such as intact flake crystals, thin flakes with good toughness, stable physical and chemical properties, conductivity, temperature resistan
2023-06-19Natural flake graphite 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 conductivity.
