The R & D team of KELAIWEI is an experienced team. The R & D leaders in the team are superior in terms of the knowledge in the industry, the intake of new knowledge, and the control of the development trend of the industry, with the brainstorming of other team members, the R & D strength of the whole team has been continuously improved. At the same time, in order to further ensure the autonomy and controllability of products, the company has also strengthened the development of the subsequent process, further improved the production process of products, and ensured the controllability of product quality.
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.
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.
In the research and development of new carbon nano supercapacitors, due to the impact of the epidemic, the consumer Festival on March 15 this year is not as high as in previous years. But Henan KELAIWEI Nano Carbon Material Co., Ltd. has always insisted on contract and credit, paid high attention to the honest and trustworthy education for employees, and paid attention to the establishment and maintenance of the company's honest and trustworthy corporate image, ensure that the products leaving the factory have passed the quality inspection of the Quality Inspection Center of KELAIWEI company, and our company insists on providing you with high-quality products. Choosing KELAIWEI company means choosing honest business partners.
In the research and development of new carbon nano-capacitor, the basic research of carbon nano-tube materials is very important. At present, China is in the dominant position in the preparation and application research of carbon nano-tube materials. The carbon nanotube material is very fine, and its conductivity and thermal conductivity are very high. Its hardness is one hundred times that of steel. The higher the purity, the stronger the performance of carbon nanotubes. The technical team of KELAIWEI carbon nanomaterials company will also continue to demand to contribute to the development of nanomaterials in our country.
Brief introduction of graphite conductive agent and carbon nanotube (CNT) conductive agent. The application of graphite conductive agent in lithium batteries can obviously improve the conductivity of lithium ions and electrons. CNT conductive agents are often used to make high-end 3C digital batteries. Almost half of high-end digital batteries can see the shadow of CNT conductive agent. The use of conductive agent is very important for lithium battery manufacturing. Conductive agent can ensure that the battery electrode can maintain a good charging and discharging performance state continuously.
Whisker carbon nanotubes can use powder alone, and the length of powder can reach up to 10μm. In the grinding process of ordinary carbon nanotubes using sand Mill, the length of carbon nanotubes will become shorter, generally, the length of carbon nanotubes after grinding is generally 0.2~2 μm. In long-cycle and high-rate lithium ion batteries, the charging and discharging battery materials will expand, using a longer-length conductive agent can maintain the conductive channel during expansion, and the cycle and magnification performance of the battery are improved.
