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.
Carbon crystal electric heating shows e3, KELAIWEI company has been working hard for the high-end nanomaterials industry in the motherland for 20 years, and has developed domestic and overseas markets by virtue of its independent technical development and high-end technical services, we have deep cooperation with enterprises in more than 60 countries. KELAIWEI company has built the project of whisker carbon nanotube powder with annual production capacity of 300 tons, and has obtained nine national authorized patents. KELAIWEI relies on its high-end nanomaterials research and development center to continuously provide customers with advanced nanomaterials and technical services.
Henan KELAIWEI Nano Carbon Material Co., Ltd. is one of the well-known enterprises in the high-end nano materials industry. KELAIWEI owns 2 international PCT patents, 9 national patents, more than 40 industry papers and 2 monograph on carbon nanotube industry...... In the field of high-end nanomaterials, the leaders of KELAIWEI company make decisions to continuously invest heavily in research and development. Our company will continue to tackle key problems, continue to break the technology monopoly of foreign industries, and make contributions to the development of nanomaterials technology in our motherland.
5G commercial business is developing in full swing, and the importance of 5G key material industry is self-evident, then who has mastered the key technology and has 5G key material supply terminal, will grasp the "sharp tool" in the development of 5G commercial equipment ". KELAIWEI group is looking forward to presenting our products and technologies in Shenzhen international 5G key material industry exhibition 2020, and communicating with you about the cutting-edge technologies of the industry.
According to KELAIWEI Carbon Nano Carbon Materials Co., Ltd, a large international company in South Korea has decided to expand the production capacity of carbon nanotubes to meet the market demand of carbon nanotubes. At present, this large enterprise has an annual production capacity of 1200 tons of carbon nanotube materials. This investment will expand the production capacity of 500 tons of carbon nanotubes, thus further strengthening its competitiveness in the carbon nanotube industry.
Carbon crystal electric heating display e3, brief introduction of carbon nanotubes. Japanese physicist Yoshima Yoshino was the first to discover carbon nanotubes. Carbon nanotubes are tubular carbon molecules. Carbon nanotubes are very, very thin and cannot be seen simply by eyes, because tens of thousands of carbon nanotubes are put side by side, it may not be as thick as a hair. According to the number of pipe layers, it can be divided into single-walled carbon nanotubes and multi-walled carbon nanotubes.
Acetylene black is a particle conductive agent, which needs more additive amount when forming the conductive network. The larger the additive amount is, the lower the proportion of active material will be, and the energy density of the battery will be reduced. The whisker carbon nanotubes have nanofibers with linear structure, the network conductive structure can be rapidly formed in the electrode with extremely low additive amount and has excellent conductive efficiency. Better performance can be maintained when the battery is multiplied or circulated.
