The specific surface area of ordinary carbon nanotubes is generally 200-300m2/g, and the specific surface energy of the material is also larger. The material is more likely to be agglomerated to reduce the surface energy. The specific surface area of whisker carbon nanotubes is 13-50m2/g, the material with lower specific surface area has lower surface energy, and the material is less prone to agglomeration, which is more conducive to the dispersion of whisker carbon nanotubes on the composite material. Only the performance of dispersed carbon nanotubes can be reflected, whisker carbon nanotubes are more conducive to the development of material characteristics.
Improving energy density is the current difficulty and pain point of lithium ion battery. Silicon carbon negative pole is the future development direction. During the charging and discharging process of lithium ion battery, the material will expand by 200 ~ 400%, the cycle performance of the battery is poor. Because of the use of grinding process to make the paste, the length of the carbon nanotube conductive agent is 0.5 ~ 1μm, and the length of the whisker carbon nanotubes is 6μm, when it is used as the conductive agent, it can still maintain the conductive network when the volume expands. KELAIWEI cooperates with Company B on the silicon carbon negative pole, and the circulation performance is improved.
The batch production project of whisker carbon nano-tube powder independently designed by Henan KELAIWEI nano-Carbon Material Co., Ltd will increase the production capacity of our company's whisker carbon nano-tube powder from 30 tons to 300 tons in the past. Therefore, the company has invested 0.45 billion yuan, the construction of product line in the 15,000-square-meter Dengfeng production base factory is expected to bring the annual output value to 0.5 billion yuan, and the recruitment information of carbon crystal bamboo wood fiberboard furniture installers.
The R & D center of KELAIWEI company has sent good news the planning department of KELAIWEI company has heard that our company has established technical cooperation with Professor Zhang Meiyun, an industry expert of Shaanxi University of Science and Technology. KELAIWEI company supports and pays close attention to Professor Zhang's R & D, KELAIWEI Nano Carbon Material Co., Ltd. insists on keeping close cooperation with scientific research institutions, strengthening communication, using technology to enhance our company's competitiveness, using technology to give back to the society, and promoting the rapid development of human society, recruitment information of carbon crystal bamboo wood fiberboard furniture installers.
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, recruitment information of carbon crystal bamboo wood fiberboard furniture installers.
Since the establishment of our company, we have adhered to the technological innovation mode of "combining production, teaching and research", and insisted on employing top industry expert teams from university research institutions to promote the technological development idea of our company, relying on the mainstay of advanced technology to realize the leap-forward development of products...... In the past 20 years, our company has "gained a firm foothold" in overseas products, equipment, technology and so on, and has comprehensively explored the domestic and foreign nanomaterials market.
The high purity carbon nanotubes produced by Henan KELAIWEI Nano Carbon Material Co., Ltd have excellent conductivity and are widely used in the field of modern automobile manufacturing. Polymer materials using carbon nanotubes have surface conductivity, so Electrostatic spraying can be carried out in the manufacture of automobile parts, thus simplifying the manufacturing process and improving the production efficiency of products, and it is helpful to reduce the pollution to the environment in production.
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.
Traditional conductive agent products can no longer meet the manufacturing requirements of new high-end lithium batteries. KELAIWEI company is willing to help you develop the high-end lithium battery conductive agent market. The new type of conductive agent products researched and developed by KELAIWEI company will be presented in the exhibition area of KELAIWEI company in "2020 International Exhibition of heat conducting and heat dissipation materials and equipment in Shenzhen Convention and Exhibition Center" on August 27th, 2020.
