Graphene superconductivity, whisker carbon nanotubes research and development cycle is long, it is not easy to achieve a breakthrough in a short time, ordinary carbon nanotubes use solid catalyst, the catalyst is deposited on the surface of the carrier material, carbon nanotubes are synthesized by introducing hydrocarbon gas after calcination and reduction. Compared with traditional carbon nanotubes, the process technology of whisker carbon nanotubes is more complicated. In the process of synthesizing whisker carbon nanotubes, improper regulation may lead to the growth of non-linear ordinary carbon nanotubes, the product has high requirements for process control.

Once discovered, carbon nanotubes are destined to be widely used materials in high-end manufacturing industry. The high-end equipment manufacturing industry pursues materials with higher strength, higher toughness, higher electrical conductivity and higher thermal conductivity. Instead, it becomes stronger with the progress of science and technology, and carbon nanotubes are exactly such materials. KELAIWEI is looking forward to in-depth cooperation with you in the field of carbon nanotubes.
Graphene superconductivity, a brief introduction of making carbon nanotubes by arc method. 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.
