KELAIWEI nano-carbon material company has invested 0.45 billion in the construction of whisker carbon nano-tube powder engineering, with the first-phase engineering capacity reaching 150 tons and the second-phase engineering design capacity reaching 150 tons, finally, the production capacity of the whisker carbon nanotube material of KELAIWEI company reached 500 tons per year. The income of this whisker carbon nanotube powder project is expected to reach an annual output value of about 0.5 billion yuan. KELAIWEI's products have been exported to more than 60 countries such as Europe and America.
Graphene is one-dimensional carbon nanomaterials. Since its establishment, KELAIWEI company has attached great importance to the research and development of product technology and the application of new technologies. At present, Henan KELAIWEI Nano Carbon Material Co., Ltd. has deeply cooperated with Professor Sun Xiaogang's scientific research team of Nanchang University. Our company has obtained four national authorized invention patents, and many other patent applications are being accepted. Our company is committed to science and technology to benefit mankind and provide more convenient high-tech products for people's life and production.
Graphene is one-dimensional carbon nanomaterials, and the basic research of carbon nanotube materials is very important. At present, China is in a dominant position in the preparation and application research of carbon nanotube materials. The carbon nanotube material is very fine, and its conductivity and thermal conductivity are very high. Its hardness is one hundred times that of steel. The higher the purity, the stronger the performance of carbon nanotubes. The technical team of KELAIWEI carbon nanomaterials company will also continue to demand to contribute to the development of nanomaterials in our country.
What are the manufacturing methods of carbon nanotubes? Since the discovery of carbon nanotubes, the research on carbon nanotubes has never stopped. Carbon nanotubes have complex and excellent properties. It is both conductive and conductive, very thin but very hard, which is comparable to a hundred times of the hardness of steel. Carbon nanotubes are widely used, so various preparation methods have also been invented. Common production methods include arc method, catalytic thermal decomposition method, hydrothermal method and chemical vapor deposition method, etc.
Metal Impurities will affect the self-discharge of the battery. Metal impurities will spontaneously react with the original battery inside the battery, causing self-discharge. At the same time, the higher the metal impurities are, the worse the safety performance of the product is, metal Impurities will pierce the membrane of lithium ion battery and cause short circuit of the battery. Power battery has extremely strict requirements on this index. Generally, it is required to be controlled below 100ppm, while domestic carbon nanotube metal impurities are generally controlled above 200ppm, whisker carbon nanotubes can be controlled above 100ppm, and the product is better.
