In order to realize the high performance and high stability of domestic carbon nanotube materials, KELAIWEI Group has researched and developed for more than 20 years. From 20 years ago when the research and development personnel set up the project to 2020, all the staff of KELAIWEI group have worked hard, it has spent 0.45 billion yuan to construct the project of processing and producing 300 tons of whisker carbon nanotube powder annually. Our new products and new technologies will also be presented to our partners at the International Exhibition of heat conduction and heat dissipation materials and equipment held in Shenzhen Convention and Exhibition Center, carbon nanotube heating wood floor manufacturer.
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.
In 2018, Henan KELAIWEI Nano Carbon Material Co., Ltd. was successfully established in Dengfeng with a registered capital of 60 million RMB. Henan KELAIWEI has an independent factory area of 13,000 square meters, planning dozens of production lines. By virtue of the 6S lean management law, all functional departments of our company are guaranteed to work scientifically and orderly and innovate actively. As of March 2020, our company has applied for 60 patents.
The R & D center of KELAIWEI company added new strength, and KELAIWEI Nano Carbon Material Co., Ltd. established deep cooperation with relevant industry experts of Zhengzhou University of light industry. KELAIWEI company hired Professor Wang Lizhen as our technical consultant. KELAIWEI company firmly believes that with the cooperation of Professor Wang, the R & D strength of KELAIWEI company will be strengthened. KELAIWEI company always pays attention to technical cooperation and communication with professionals at home and abroad.
Some progress has been made in the modification of the traditional zinc-manganese battery by the whisker carbon nanotubes. Compared with the traditional zinc-manganese battery, the constant current discharge energy density of the zinc-manganese battery added with the whisker carbon nanotubes increases by 30-120%, it is of great significance and broad market prospect to use this research result to carry out technical transformation of primary battery to improve the performance of zinc-manganese battery. At present, this product is still in the laboratory research stage, at present, we are actively promoting the development progress of cooperation with enterprises.
A power battery production and research institution in Guangdong province is seeking to purchase a batch of power whisker carbon nanotubes for its new generation of power battery development. The other party puts forward high requirements such as purity, transportation and storage, stability, high requirements in terms of supply and so on our products fully meet the needs of the other side Henan KELAIWEI Nano Carbon Material Co., Ltd. Has studied whisker carbon nanotubes for more than 20 years, with completely independent intellectual property rights, it can process whisker carbon nanotubes with purity of over 95%, with a shelf life of 6 months and stable performance.
The ultra-high purity whisker carbon nanotubes produced by Henan KELAIWEI nano-Carbon Material Co., Ltd. WhiskerCNT-U its purity can reach nearly 99.99% without impurities, and its aperture can be controlled between 1 nanometer and 5 nanometer, its length can be controlled between 1 nm and 15 nm, and whisker carbon nanotubes are very suitable additives for lithium ion battery manufacturing and application.
