May Day 2020 is a special Labor Day. The staff of Henan KELAIWEI Nano Carbon Material Co., Ltd. should rest and work on duty under the protection of individual epidemic. KELAIWEI company delivers holiday comfort and welfare to all employees. Under the influence of the current epidemic situation, the economic situation is grim. KELAIWEI company insists on doing a good job in protection and actively reproduces to contribute to the economic development of our city.
KELAIWEI company learned that South Korea LG Chemical invested 0.374 billion yuan to expand the production of its carbon nanotubes (CNT) factory, so as to increase the annual production of carbon nanotubes (CNT) to 1200 tons. As a new generation of materials, carbon nanotubes are widely used in the field of application, such as aircraft manufacturing industry, automobile parts manufacturing, battery and semiconductor manufacturing industry, etc.
The brief introduction of making carbon nanotubes by electric arc method for the heating of corrugated carbon crystal wall. Carbon nanotubes were first discovered by Japanese physicists, and the arc method was also first invented by Japanese scientists. The arc method is to rearrange the structure of carbon atoms in the high temperature environment produced by the arc caused by the graphite electrode of yin and yang poles in the reaction chamber containing the pressure inert gas, so as to obtain a single-wall carbon nano-tube. Since then, the arc method has been continuously improved and perfected day by day.
The specific surface area of whisker carbon nanotubes is generally 13~50 m2/g, and that of ordinary carbon nanotubes is above 200 m2/g. The larger the specific surface area is, the worse the dispersion performance of the product is, the agglomeration of conductive agents is more likely to occur. In lithium ion batteries, the larger the specific surface area is, the greater the gas production of lithium ion batteries will be in the long-term cycle process, smaller specific surface area is conducive to improving the cycle performance of lithium ion batteries and reducing the gas production of batteries in the later cycle process.
