KELAIWEI is backed by Henan denggou group. The predecessor of Zhengzhou Dengcao Group Co., Ltd. is the Dengcao coal mine established in 1973. After years of development, Dengcao group has gradually covered many fields such as coal, finance, education, real estate and so on, and has accumulated a lot of shopping experience. With the strong support of the group company, KELAIWEI actively promotes technology and product innovation, increases investment and strives to move towards high-tech enterprises.
KELAIWEI company has successively invested 0.55 billion yuan to carry out in-depth cooperation with the research and development team led by Professor Sun Xiaogang of Nanchang University in China for a long time, and has successively invested 0.45 billion yuan in Henan to build the first phase of whisker carbon nano-tube powder project and the second phase of whisker carbon nano-tube powder project, the production capacity of whisker carbon nano-tube powder of Henan KELAIWEI nano-Carbon Material Co., Ltd. has been improved qualitatively, reaching 300 tons/year, which is insufficient for carbon nano-materials.
Since its establishment, Henan KELAIWEI nano-Carbon Material Co., Ltd. has been insisting on promoting the development of China's high-end nano-material industry, breaking the foreign monopoly on high-end nano-material technology as its own duty, and insisting on independent research and development and innovation, take technical force to serve the motherland and technological progress to obtain enterprise benefits as the driving force for development. Relying on complete intellectual property rights, we have completed product research and development, process design and mass production, and continuously supply high-end technical products to customers in batches.
KELAIWEI's monthly happy enterprise construction plan and enterprise lean work inspection meeting will be held on schedule. At the meeting, KELAIWEI Company was required to strengthen internal communication, sharing and learning, make full use of preferential policies of science and technology, internal cost control, external cooperation, improve work efficiency and do a good job in daily sales, and pay attention to do a good job in the publicity and construction of the corporate image, at the same time, to quickly promote the development of the company's various work.
There are many production methods of carbon nanotubes, among which the widely used production method of carbon nanotubes is arc discharge method, which is also a relatively simple method in the preparation of carbon nanotubes. Therefore, correspondingly, the purity of carbon nanotubes made according to this method is also relatively low. In fact, what this method obtains is multilayer carbon nanotubes. Henan KELAIWEI Nano Carbon Material Co., Ltd. has been able to produce whisker carbon nanotubes with purity up to 99.99%, deficiencies of carbon nanomaterials.
How is carbon nanotubes made by chemical vapor deposition? Carbon nanotube materials are widely used and have strong properties, but their production is very low and the manufacturing process is complex. Therefore, scientists have continuously improved the manufacturing methods. Chemical vapor deposition method is used to produce carbon nanotubes, and its production efficiency is still relatively high. By chemical vapor deposition, carbon-containing gases are cracked by catalysts to obtain carbon nanotubes.
Conductive graphite is a kind of micrometer graphite sheet. Due to its large particle size, conductive graphite cannot form enough conductive network with a very small addition amount in lithium ion battery, it cannot show good performance when added to the cathode material of lithium ion battery. Because of its small diameter, whisker carbon nanotubes have the characteristics of linear structure and long length. This characteristic determines that graphite is very suitable for application in lithium battery, heating and other fields.
