The resistivity of powder is an important index to characterize the electrical conductivity of materials. The lower the resistivity, the better the electrical conductivity of products, under the pressure of 20Mpa, the powder resistivity value of whisker carbon nanotubes can reach below 8mΩ · cm, and the resistivity of ordinary carbon nanotubes is above 15mΩ · cm, the resistivity of conductive carbon black is above 100mΩ · cm, and the resistivity of whisker carbon nanotubes is the lowest, which can ensure ultra-high conductivity on lithium ion batteries and composite materials.
Whisker carbon nanotubes belong to coarse diameter and long length. Ordinary carbon nanotubes are short in length and fine in diameter after grinding. Ordinary carbon black belongs to granular conductive agent. Using the principle of composite conductive agent, ordinary carbon nanotubes and carbon black are compounded to produce composite conductive agent paste. The composite conductive agent paste gives full play to the advantages of various conductive agents and can still maintain a good conductive network in high magnification and circulation, it is mainly applied to silicon carbon negative pole and high-rate battery.

Carbon crystal frescoes heater installation, there is a new material-carbon nanotubes is widely used in modern manufacturing industry. The strength of carbon nanotubes can reach 100 times of that of steel, and its strong thermal conductivity and conductivity can be equivalent to that of diamond and copper. Henan KELAIWEI Nano Carbon Materials Co., Ltd. learned that a large multinational enterprise in South Korea recently invested more than 300 million yuan to expand the capacity of carbon nanotubes, in the future, the competition in the carbon nanotube industry is bound to have a "growing momentum".
"Technology is the mainstay, product performance is high, and service is satisfactory" is the business philosophy that the technical staff of Henan KELAIWEI Nano Carbon Material Co., Ltd insist on implementing in the development of more than 20 years. The R & D team of KELAIWEI, led by Professor Sun Xiaogang, the top domestic nanomaterials research expert, has applied for more than 100 patents and has 9 national property rights patents. KELAIWEI pursues promoting the leapfrog development of nanomaterials with technological progress.
High-end application materials with high strength, excellent electrical conductivity, strong thermal conductivity and mass production have always been pursued by high-end commercial power battery manufacturers. And the whisker carbon nanotubes materials are those nanomaterials with excellent properties. The whisker carbon nanotubes have excellent mechanical properties, physical and chemical properties, and have been mass produced and supplied to the market by Henan KELAIWEI nanometre Carbon Materials Co., Ltd.
What are the classification of Carbon Nanotubes? Carbon nanotubes are composed of several layers of hexagonal carbon atoms. The Axis size is only micrometer, the two ends are closed, and the radial size is only nanometer, according to the difference of carbon six-side type along the axis direction in the industry, carbon nanotubes are classified as follows, namely, saw carbon nanotubes, armchair carbon nanotubes and spiral carbon nanotubes, and the installation of carbon crystal murals heater.
KELAIWEI company established itself with technology the research and development experience of KELAIWEI company is more than 20 years in 2006, Professor Sun Xiaogang's team started the research and development of whisker-like nanometre two years later, they developed whisker-like carbon nanotubes five years later, whisker-like carbon nanotubes ten tons mass production equipment and finished Process development industrial standard production line with annual output of 30 tons in 2018 put into use KELAIWEI company has established Jiangxi research and development base and Henan research and development base successively, installation of carbon crystal mural heater.
