What is graphite carbon fiber? The carbon fiber obtained after Graphite processing of carbon fiber at ultra-high temperature is graphite carbon fiber. The graphitization temperature is as high as over 2000 degrees Celsius, generally within 3000 degrees Celsius. Graphite carbon fiber and nano carbon fiber materials are different. In addition, the higher the temperature of graphitization environment is, the larger the graphite microcrystals contained in the fiber will be.

KELAIWEI company's technological research on the purity of whisker carbon nanotubes has made another breakthrough. At present, KELAIWEI company can improve the purity of whisker carbon nanotubes to more than 99.95% through its own complex technology and technology. Therefore, KELAIWEI company's product production center can provide you with high-end whisker carbon nanotube products with high quality, high stability and ultra-high purity, and directional carbon nanotube arrays.
Improving energy density is the current difficulty and pain point of lithium ion battery. Compared with granular conductive agent, whisker carbon nanotubes is a kind of fibrous conductive agent, which can reduce the addition amount of conductive agent. Due to the flexibility of whisker carbon nanotubes, it can reduce the additive amount of the adhesive. Compared with the complete use of granular conductive agent, the amount of the adhesive can be reduced by 0.5~1.0% by whisker carbon nanotubes. By reducing the adhesive, the proportion of the positive electrode material can be increased, the energy density of the battery is improved.
Recently, a high-end lithium battery manufacturer in Shanghai inquired through the Internet that Henan KELAIWEI nano-Carbon Material Co., Ltd. produces double-rate whisker carbon nanotubes for lithium batteries suitable for high-end performance applications. The use of multiplied whisker carbon nanotubes can significantly improve the conductivity, storage capacity and service life of the battery. The purity of multiplied whisker carbon nanotubes of KELAIWEI company can reach 95.99%, and the thermal conductivity of a single whisker is higher than 1200W/m.k, advanced performance.
Whisker carbon nanotubes have been proved to be a kind of conductive additive with better effect by nanomaterials industry. Studies have proved that the conductivity and thermal conductivity of whisker carbon nanotubes with purity as high as 99.95% are far better than that of traditional carbon black materials and higher than that of traditional carbon nanotubes with high metal impurities. KELAIWEI company has been supplying high-purity whisker carbon nanotubes for internationally renowned lithium battery brands.
