Henan KELAIWEI Nano Carbon Material Co., Ltd. is an international advanced manufacturer of research, development, design and production of high-end nano materials and process equipment. Our company respectively established Jiangxi KELAIWEI company and Henan KELAIWEI company. KELAIWEI company has completely independent intellectual property rights, focusing on high-end nanomaterials technology research and development, process design, equipment manufacturing, technical services and so on.
A brief introduction to the fabrication of carbon nanotubes by arc method. Carbon nanotubes were first discovered by Japanese physicists, and the arc method was also first invented by Japanese scientists. The arc method is to rearrange the structure of carbon atoms in the high temperature environment produced by the arc caused by the graphite electrode of yin and yang poles in the reaction chamber containing the pressure inert gas, so as to obtain a single-wall carbon nano-tube. Since then, the arc method has been continuously improved and perfected day by day.
Since its establishment in 2018, Henan KELAIWEI Nano Carbon Material Co., Ltd has paid great attention to the development of high-end nano material technology and the formation of talent team. In order to realize the scientific research goal of clevere company, our company has maintained deep cooperation with many domestic universities and scientific research institutions. For example, the team of Professor Sun Xiaogang from Nanchang University, Donghua University, Zhengzhou University of light industry and other universities continuously input product technology and talent strength for our company.
For the price of carboxated graphite multi-walled carbon nanotubes, KELAIWEI Nano Carbon Material Co., Ltd. invested 0.55 billion yuan in 2017 and 2018 to build production research and development centers: Jiangsu KELAIWEI production research and development center and Henan Dengfeng KELAIWEI production research and development center. KELAIWEI Nano Carbon Material Co., Ltd. has recently expanded the production of whisker carbon nano-tube powder in Henan's 13,000-square-meter production base, with an annual output of 300 tons.
Improving energy density is the current difficulty and pain point of lithium ion battery. Silicon carbon negative pole is the future development direction. During the charging and discharging process of lithium ion battery, the material will expand by 200 ~ 400%, the cycle performance of the battery is poor. Because of the use of grinding process to make the paste, the length of the carbon nanotube conductive agent is 0.5 ~ 1μm, and the length of the whisker carbon nanotubes is 6μm, when it is used as the conductive agent, it can still maintain the conductive network when the volume expands. KELAIWEI cooperates with Company B on the silicon carbon negative pole, and the circulation performance is improved.
A lithium battery research and development company in Jiangsu needs 100 grams of whisker carbon nanotubes, which requires absolute low-value metal impurity content and can be applied to high-rate batteries and power batteries. Henan KELAIWEI carbon nanomaterials Co., Ltd. can provide power whisker carbon nanotubes with purity as high as 95% or more. Its graphite hardness is above 65%, the residual metal is less than 100ppm, and the average spacing between carbon tubes is less than 0.3384 nanometers.
The working temperature of the far infrared paper (FIRPs) developed and manufactured by Henan KELAIWEI Nano Carbon Material Co., Ltd. is suitable for the working environment within 300 degrees Celsius, and its far infrared emissivity can reach 99.80% at the same time, it also has higher electrothermal conversion efficiency, it can reach 99.50%, so the far infrared paper of our company can be widely used in the manufacture of electric heating products and equipment, and the price of carboxyl graphite multi-walled carbon nanotubes.
