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.
In 2020, KELAIWEI had been deeply engaged in the research and development and preparation of nanomaterials for 20 years. Our company fully owns independent intellectual property rights of relevant industries and has applied for 106 patents (including 9 national authorized invention patents and 2 international PCT patents). Our deep cooperation customers have spread all over the world (more than 60 countries such as Asia, America, Europe and Africa). All the staff of KELAIWEI are forging ahead and looking forward to establishing a deep partnership with you.

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.
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, graphene conducts conduction through point-surface contact. Generally, the larger the contact surface is, the better its conductivity will be. Therefore, carbon nanotube materials will be widely used 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.
How hard is nano-Carbon? Is carbon nanotube a stealth material? Carbon nanotubes are excellent stealth materials. Carbon nanotubes have stealth effect on infrared. The wavelength of infrared and radar wave is much larger than that of nanoparticles, and the specific surface area of nanoparticles material is 3 orders of magnitude or 4 orders of magnitude of conventional coarse powder, thus nanoparticles material can easily reduce the reflectivity of wave. It also has excellent stealth ability to electromagnetic waves.
Due to the adoption of pickling or low-temperature purification process, the graphitization of ordinary carbon nanotubes is generally below 30%, and the whisker carbon nanotubes are purified at a high temperature of 300℃, and carbon atoms are rearranged at high temperature, with the passage of heat preservation time, the arrangement of carbon atoms is more and more regular, thus the performance in all aspects is better. Generally, the graphitization degree of whisker carbon nanotubes purified at high temperature can be above 80%, the thermal conductivity and conductivity of materials of products with high graphitization degree have been greatly improved.
