KELAIWEI company has invested 0.55 billion yuan to carry out deep cooperation with the research and development team led by Professor Sun Xiaogang of Nanchang University in China for a long time. And invested 0.45 billion yuan successively in Henan to build the first phase of whisker carbon nano-tube powder project and the second phase of whisker carbon nano-tube powder project, which made the production capacity of whisker carbon nano-tube powder of Henan KELAIWEI nano-Carbon Material Co., Ltd achieve qualitative improvement, up to 300 tons/year.
What are the manufacturing methods of multi-walled carbon nanotubes for carboxation? Since the discovery of carbon nanotubes, the research on carbon nanotubes has never stopped. Carbon nanotubes have complex and excellent properties, which are both conductive and conductive, very thin but very hard, compared with a hundred times of steel hardness, carbon nanotubes are widely used, so various preparation methods have also been invented. Common production methods include arc method, catalytic thermal decomposition method, hydrothermal method and chemical vapor deposition, etc. Multi-walled carbon nanotubes are carboxylated.
Henan KELAIWEI Nano Carbon Material Co., Ltd., which has an independent research and development center, focuses on the research and development of high-end nano material technology and mass production process equipment. Through the technology leader Professor Sun of KELAIWEI company and the experts of research institutions in colleges and universities, combining with the industry demand research, we have carried out the project establishment and research of product technology. Our company has applied for more than 60 patents, and the publishing industry focuses on two, 9 national invention patents.
Since its establishment, Henan KELAIWEI Nano Carbon Material Co., Ltd. has adhered to efficient management and earnestly studied and applied 6S lean management rules of the group company. KELAIWEI company has obtained the 6S lean management law Bronze certification of the group company within a short period of one year, which is a great recognition and encouragement to all the staff of KELAIWEI company. Our company will work together to learn and strive to improve work efficiency, complete the established annual goals.
The utilization rate of active materials in lead-acid battery is low, the energy density is small, and the circulation performance is poor. Adding carbon whisker nanotubes to the negative pole of lead-acid battery can greatly improve the conductivity of the polar plate, the consistency of lead-acid battery can be improved well. Because it is a linear conductive agent, it can still maintain the conductive network in a long cycle, so the cycle characteristics of the battery can be improved. Moreover, due to the addition of whisker carbon nanotubes, the charging and discharging depth of lead-acid battery can be appropriately improved, and the energy improvement can be improved. KELAIWEI and Y Company have conducted in-depth cooperation in the field of lead-acid.
A lithium battery manufacturer in Guangdong put forward higher requirements for the purity of carbon nanotubes when researching and developing a new product-high-performance lithium battery product. At first, it was considered to be imported from abroad, but at last, it was found that, some foreign manufacturers asked too much, and later found through the network that our products carbon nanotubes have high quality, low price and high purity. The purity of our whisker carbon nanotubes is as high as 99.9%.
Henan KELAIWEI Nano Carbon Material Co., Ltd found that whisker carbon nanotubes were used to make CNT transparent conductive film for their excellent conductivity. CNT transparent conductive film made of whisker carbon nanotubes has stable chemical performance and excellent conductive characteristics, moreover, it has both thermal conductivity and very good mechanical properties (the hardness of whisker carbon nanotubes is 100 times that of steel).
