In the aspect of powder dispersion, breaking the technical barrier that carbon nanotubes must use conductive paste, the powder produced by the company can be directly added in the homogenization process of lithium ion battery, and the use process is very convenient and concise, carbon nanotubes are dispersed evenly in the positive electrode materials. After years of early research and development work, although the products have only recently started mass production, they have been recognized by the vast number of peers, the product performance is similar to that of similar products abroad and can replace imported products.
Since the establishment of our company, we have adhered to the technological innovation mode of "combining production, teaching and research", and insisted on employing top industry expert teams from university research institutions to promote the technological development idea of our company, relying on the mainstay of advanced technology to realize the leap-forward development of products...... In the past 20 years, our company has "gained a firm foothold" in overseas products, equipment, technology and so on, and has comprehensively explored the domestic and foreign nanomaterials market.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has always maintained close technical cooperation with first-class domestic universities and scientific research institutions such as Zhengzhou University of Light Industry, Donghua University and Nanchang University. The high-end nanomaterials products developed by KELAIWEI company have broad application scenarios in high-end lithium ion energy storage battery manufacturing at home and abroad, electrothermal converter preparation, high-end nanomaterials and other industries.
The project of the annual output of 300 tons of carbon nanotubes of Henan KELAIWEI company has been implemented in Kaifeng, Henan. Henan KELAIWEI company invested 0.45 billion yuan in the research and development, production and manufacture of high-end nanomaterials and equipment. Promote social development with science and technology, and create convenient and effective products for people with science and technology. At the same time, KELAIWEI company insists on promoting the company's development with high and new technology products, contributing little to Kaifeng's economic development.
The research on hydrogen storage carbon nanoparticles has been successful, and the application of carbon nanotubes in modern manufacturing industry has a very good prospect. Carbon nanotubes have high elasticity, super hardness (100 times the strength of steel), good infrared absorption performance, high hydrophobic property, smiling volume, very lightweight quality, the density is very low and has very good insulation and other characteristics, so we can conduct in-depth research and expansion on the industrial application of carbon nanotubes.
The research on hydrogen storage carbon nanoparticles has been successful. How did carbon nanotubes be discovered? Carbon nanotubes were discovered in the laboratory in 1991 by Japanese physicist Yoshiko Hiroshima. As usual, Yoshima Yoshino, who works in the NEC laboratory of Tsukuba in Japan, was observing the carbon fiber made by the arc method by using the transmission electron microscope, and unexpectedly found "carbon nanotubes". Carbon nanotubes are a kind of "tubular" carbon molecules, whose skeleton is honeycomb-shaped structure.
The graphite degree of whisker carbon nanotubes is high. Using X-ray diffraction, the graphitization degree of the product calculated by a specific formula can reach more than 90% at most. In Raman spectrum detection, the D/G of the product is generally below 0.2, and the D/G ratio of ordinary carbon nanotubes is generally above 2. The size of D/G reflects the number of defects of the product. The larger the D/G is, the more defects of the product, the closer the whisker carbon nanotubes are to the ideal material, and the fewer defects of the product, the closer to the performance of the ideal material.
