By virtue of its own national invention patent technology and technical professional service team and sales team, KELAIWEI nano-carbon materials have been spread through market inspection and customer reputation in the past 20 years. Cleway's products have been sold well in China and abroad. At present, our company has invested 0.45 billion to build the whisker carbon nanotube powder project with a capacity of 300 shield/year. And cooperate with customers in Europe, America, Asia, Africa and other regions to actively expand the nanomaterials market.
How were carbon nanotubes 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.
Cleway nano carbon material company is a company with patriotic feelings. Facing the monopoly of foreign technology to our country, KELAIWEI people are determined to break their monopoly and become the "leader" of high-end nanomaterials industry, contributing to the society and the country. After more than 20 years of research and development, KELAIWEI carbon nanotubes, far infrared paper (FIRPs) and other technologies are the mainstay, and its products are exported to domestic and overseas markets.
The sixth of the series of "reviewing the development history · encouraging young talents to strive for the first" of KELAIWEI company: events of 2013 KELAIWEI company has been insisting on the tradition of technology research and development since its establishment, professor Sun of our company led the staff of the R & D center of KELAIWEI to make continuous technological breakthroughs, which improved the technology and equipment of the whisker carbon nanotubes prepared by our company to 2~4kg/h more than four times higher than the previous equipment output, carbon nanotube nanometer copper manufacturer.
Improving energy density is the current difficulty and pain point of lithium ion battery. Compared with granular conductive agent, whisker carbon nanotubes is a kind of fibrous conductive agent, which can reduce the addition amount of conductive agent. Due to the flexibility of whisker carbon nanotubes, it can reduce the additive amount of the adhesive. Compared with the complete use of granular conductive agent, the amount of the adhesive can be reduced by 0.5~1.0% by whisker carbon nanotubes. By reducing the adhesive, the proportion of the positive electrode material can be increased, the energy density of the battery is improved.
Recently, a high-end lithium battery manufacturer in Shanghai inquired through the Internet that Henan KELAIWEI nano-Carbon Material Co., Ltd. produces double-rate whisker carbon nanotubes for lithium batteries suitable for high-end performance applications. The use of multiplied whisker carbon nanotubes can significantly improve the conductivity, storage capacity and service life of the battery. The purity of multiplied whisker carbon nanotubes of KELAIWEI company can reach 95.99%, and the thermal conductivity of a single whisker is higher than 1200W/m.k, advanced performance.
Henan KELAIWEI Nano Carbon Material Co., Ltd., which has the manufacturing patent of whisker carbon nanotubes, has reached a contract with well-known lithium battery manufacturers at home and abroad to supply whisker carbon nanotubes. In view of the sharp increase in the demand for whisker carbon nanotubes, therefore, the management layer of Henan KELAIWEI nano-Carbon Material Co., Ltd has decided to invest 0.45 billion yuan to expand the production capacity of whisker carbon nanotubes to 500 tons per year, which is a manufacturer of carbon nanotubes nano-copper.
