In the aspect of powder dispersion, breaking the technical barrier that carbon nanotubes must use conductive paste, the powder produced by the company can be directly added in the homogenization process of lithium ion battery, and the use process is very convenient and concise, carbon nanotubes are dispersed evenly in the positive electrode materials. After years of early research and development work, although the products have only recently started mass production, they have been recognized by the vast number of peers, the product performance is similar to that of similar products abroad and can replace imported products.
By virtue of its own national invention patent technology and technical professional service team and sales team, KELAIWEI nano-carbon materials have been spread through market inspection and customer reputation in the past 20 years. Cleway's products have been sold well in China and abroad. At present, our company has invested 0.45 billion to build the whisker carbon nanotube powder project with a capacity of 300 shield/year. And cooperate with customers in Europe, America, Asia, Africa and other regions to actively expand the nanomaterials market.
Ultra-high purity whisker carbon nanotube powder products, high-end far infrared heating paper products, A series of carbon-based nanomaterials, such as technology-innovative carbon-based composite derivative products and high-end whisker carbon nanotube conductive paste, have completely independent intellectual property rights, henan KELAIWEI Nano Carbon Material Co., Ltd. Supports technical innovation to meet the needs of high-end nano material customers, silicon crystal heating plate and carbon fiber.
On August 27th, 2020, the International Exhibition of heat conduction and heat dissipation materials and equipment in Shenzhen, China will have a concentrated presentation of new products and technologies of "a large wave" Heat Conduction materials of KELAIWEI group. If you want to know about new technologies in the heat conduction materials industry, new trends and new products, KELAIWEI exhibition area will show you our strength. Our technical staff will also introduce the company's "secret" products to you.
Carbon nanotubes do not block the transmission and diffusion of lithium ions, but graphene will hinder the transmission of lithium ions to a certain extent, because carbon nanotubes are transmitted by a little linear contact, however, graphene conducts conduction through point-surface contact. Generally, the larger the contact surface is, the better its conductivity is, the more widely the carbon nanotube material will be applied in the battery industry Henan KELAIWEI Nano Carbon Material Co., Ltd has invested 0.45 billion yuan in the research and production of whisker carbon nanotubes, silicon crystal heating plate and carbon fiber.
Brief analysis of application of high-end lithium battery conductive agent. Lithium battery, as energy storage equipment, has the characteristics of pursuing long service life, large capacity and mass production of manufacturing materials. The use of conductive agent can solve the net reaction of the battery when charging and discharging rapidly, and enhance the infiltration of electronic conductivity and electrolyte to the battery pole, thus prolonging the battery life. It can also effectively reduce the contact resistance of the electrode and improve the electron migration rate.
Kochin Black is also a kind of chain-like conductive agent with excellent conductivity, but the resistivity of Kochin Black is larger than that of whisker carbon nanotubes, and its specific surface area is also larger than that of whisker carbon nanotubes, so it is relatively more difficult to disperse, it is not conducive to the exertion of material characteristics. Like Kochin black, carbon nanotubes can also be used as conductive agents for lithium batteries. Carbon nanotubes can effectively combine with active substances in lithium batteries, forming a website structure of point-line combination, effectively improving the service life of batteries and reducing daily use losses.
