KELAIWEI Group has researched and developed for more than 20 years in order to realize the high performance and high stability of domestic carbon nanotube materials. From the establishment of the project by R & D personnel 20 years ago to 2020, all the staff of KELAIWEI group have spent 0.45 billion yuan to construct the project of processing and producing 300 tons of whisker carbon nanotube powder annually through hard work. Our new products and 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.
Quotation of carbon nanotube heat sink, brief analysis of application of high-end lithium battery conductive agent. Lithium battery, as energy storage equipment, has the characteristics of pursuing long service life, large capacity and mass production of manufacturing materials. The use of conductive agent can solve the net reaction of the battery when charging and discharging rapidly, and enhance the infiltration of electronic conductivity and electrolyte to the battery pole, thus prolonging the battery life. It can also effectively reduce the contact resistance of the electrode and improve the electron migration rate.
Henan KELAIWEI Nano Carbon Material Co., Ltd. is located in Henan province, which is jointly founded by Jiangxi KELAIWEI company and Dengcao group. Our factory covers an area of 12000 square meters and has established ten production lines. With the best-selling products of our company, we have launched two new production lines of whisker carbon nanotubes, with an annual output value of 0.5 billion yuan. KELAIWEI's products are sold to more than 60 countries around the world.
Professor Sun Xiaogang, chief technical expert of KELAIWEI Nano Carbon Material Co., Ltd., led colleagues in the technical center of KELAIWEI company to achieve fruitful technological research and development success again. Up to now, the technical staff of KELAIWEI company have published more than one hundred papers on research results, published (participated in the compilation) The English industry focuses on four papers, applied for more than 60 patents, and obtained 9 national patent authorizations, and obtained two international PCT patent technologies.
In the application of carbon nanotubes, capacitors are also an important application direction. Capacitor's main function is to store electricity and provide electricity for various electronic products and mechanical equipment, which is widely used in mechanical fields and other links. The diameter of whisker carbon nanotubes is generally 50-200nm, and the length is from several micrometers to dozens of micrometers. They have large specific surface area and good electrical conductivity, and are the ideal electrode materials for supercapacitors, the small supercapacitors cooperated with W are mainly applied to intelligent three-meter.
A large radiator company in Northeast China aimed at domestic and foreign domestic radiator market, and launched a medium and high-end domestic radiator. Its products also use far infrared paper. The quality of the products provided by several suppliers of far infrared paper that once cooperated with was uneven, it also leads to the great difference in the performance of different batches of its products. Finally, the cooperation with other manufacturers has been interrupted after the application of the far infrared paper of KELAIWEI company, because no matter the price, after-sales service, the performance is still due to other manufacturers, carbon nanotube heat sink quotation.
Whisker carbon nanotubes have higher crystallization and purity than traditional carbon nanotube materials, and are easier to disperse. Therefore, the ultra-high purity whisker carbon nanotubes can improve the cycle performance and magnification performance of lithium batteries better than traditional carbon nanotubes, so they are increasingly Selected as additives by high-end lithium ion battery manufacturers. Henan KELAIWEI Nano Carbon Material Co., Ltd. has made abundant research achievements in the field of whisker carbon nanotubes.
