Dr. Li Yingyi, associate professor, presided over and participated in the national science and technology support plan, National Natural Science Foundation, Provincial Natural Science Foundation and provincial education department fund, and won the third prize of Jiangxi natural science in 2011 (the third prize). Research Fields: synthesis and application of carbon nanotubes, nano new energy materials, rare earth functional materials, LED optical conversion materials, lithium ion batteries, nano-reinforced composite materials, etc. Currently, he is the project team leader in the R & D team of KELAIWEI, have rich development experience.
In 2020, KELAIWEI had been deeply engaged in the research and development and preparation of nanomaterials for 20 years. Our company fully owns independent intellectual property rights of relevant industries and has applied for 106 patents (including 9 national authorized invention patents and 2 international PCT patents). Our deep cooperation customers have spread all over the world (more than 60 countries such as Asia, America, Europe and Africa). All the staff of KELAIWEI are forging ahead and looking forward to establishing a deep partnership with you.
After more than 20 years of rapid development, Henan KELAIWEI Nano Carbon Material Co., Ltd. has recently built several production lines in the 13000-square-meter Dengfeng plant with the company's capital investment of 0.45 billion yuan. And the related production process, manufacturing equipment, technical patents and so on are independently developed by our company and have relevant patents. Our products are sold to overseas and domestic provinces, and our cooperative customers highly recognize the products of KELAIWEI company.
KELAIWEI company applies for national authorized patent invention. As of March this year, KELAIWEI company had obtained four national authorized patents. Henan KELAIWEI Nano Carbon Material Co., Ltd. is a technical company. At the beginning of its establishment, it paid great attention to the formation of technical team, capital investment and the manufacture of advanced equipment and technology. KELAIWEI company, which has accumulated technology for 20 years, is bound to make further achievements in technology research and development.
Anode conductive additives are needed in the manufacture of high-end lithium ion battery products to increase battery performance. Nowadays, the commonly used carbon black materials have affected the manufacture of lithium batteries with higher performance. At present, a new material carbon nanotubes has gradually been paid more and more attention by battery manufacturers because of its better conductivity and thermal conductivity, and it can save more than 30% of conductive materials, and put into applied research.
The floor heating made of carbon fiber cable should be on guard! Carbon fiber cable floor heating is also called carbon crystal floor heating promotes the irregular movement of carbon atoms through voltage difference, and the irregular movement between carbon atoms generates friction, which generates heat, in order to achieve heating but using carbon fiber heating cable to make floor heating, there is no unified national regulatory standard in the industry at present, at the same time, the carbon fiber heating cable will seriously affect the heating effect after some poor contact conditions occur at the joint port, so it is necessary to carefully choose this kind of electric heating products, about carbon-based nanomaterials.
As for carbon-based nanomaterials, the whisker carbon nanotubes belong to linear structure, and the product does not agglomerate and twine. At the same time, the pipe diameter is relatively thick, and the general diameter is 50-200nm. The product fan Dehua's strength is relatively weak, and it is not easy to produce large agglomeration, it is easier to disperse the products. The diameter of ordinary carbon nanotubes is relatively small, and the agglomeration and winding are serious. At the same time, Fan Dehua has great strength, which is easy to agglomerate and more difficult to disperse. It needs to use special grinding technology to make slurry for treatment, it is more convenient to use by opening the aggregate determination.
