For carbon nano-materials, KELAIWEI company spent many years developing far infrared emission paper (FIRPs), and completed the product verification from sample to small test and to medium test, the product has been fully verified by customers and has achieved many remarkable achievements. At present, a pilot production line with an adult production capacity of 2 million m2 has been built, and a heating paper testing laboratory has been built, various heating papers can be customized according to customers' needs to meet the needs of different application scenarios, carbon nano-materials.
KELAIWEI makes high-performance and stable carbon nanotubes. At the beginning of its establishment, KELAIWEI paid attention to maintaining technical advantages and maintained close cooperation with university research institutions and expert teams. Our company has deeply cooperated with Professor Sun Xiaogang's team and has applied for more than 100 invention patents, of which nine have obtained national authorized invention patents and two international PCT patents. Relying only on technical advantages, KELAIWEI's products have been completed from Henan and Jiangxi to more than 60 countries in the world.
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.
The long conjugated chain segment of single chiral carbon nanotubes was successfully synthesized by our research group of Professor Du Pingwu of China University of Science and Technology. It is reported that the introduction of long conjugated chain synthesis of single chiral carbon nanotubes has been published in the form of a cover article in The Journal of the American Chemical Society. This achievement is of great significance and will provide conjugated polymer templates for the manufacture of ultra-pure single-walled carbon nanotubes. At the same time, it will also have great reference significance for the preparation of single chiral carbon nanotubes by solution method.
Henan KELAIWEI Nano Carbon Material Co., Ltd. will briefly introduce carbon nanotubes to you today. Carbon nanotube materials were first discovered in coking materials of ethylene cracking furnaces in the last century. The ultra-high strength of carbon nanotubes can be 100 times that of steel, and at the same time it has good electrical and optical characteristics. After being used as the battery anode additive, it can reduce 30% of the conductive materials, and filling the anode of the required materials can greatly improve the battery capacity.
Conductive agents are widely used. What is the future development of conductive agents? Conductive agents include traditional conductive agent materials represented by carbon black, and in recent years, new high-end conductive agent materials represented by carbon nanotubes have been developed. Various conductive agents are constantly appearing in the laboratory. The new conductive agent graphene has not been applied on a large scale, because its cost is too high, but its performance is far higher than that of traditional conductive agents such as carbon black. With the arrival of mass production of graphene, it is bound to be widely used in the future.
Compared with graphene, the internal structure of whisker carbon nanotubes is linear, which determines that whisker carbon nanotubes can quickly form a network structure in various application products. Graphene is generally not suitable to be used as a separate conductive agent. At the same time, flaky graphene is easy to block lithium ions in the layered direction, and lithium ions can only be transmitted through the lamellar surface. At the same time, it is easy to hang functional groups on the edge of graphene, it is not only beneficial to improve electrode conductivity.
