The significance of the preparation of carbon nanotubes, from the establishment to the development of KELAIWEI company (the products are exported to more than 60 countries around the world, and Jiangxi and Henan companies are established), has always insisted on providing high-end carbon nanomaterials, adhere to technological progress and rely on technology to serve customers. KELAIWEI company has established a professional and expert after-sales technical team, which is always ready to provide technical support to customers and help them solve their questions and demand problems in the use of products. KELAIWEI is willing to develop together with you and build a century-old famous enterprise.
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.
Since the establishment of Henan KELAIWEI Nano Carbon Material Co., Ltd., relying on the technical accumulation of the company's technical team for more than 20 years, it has achieved a leap-forward and rapid development. KELAIWEI company has developed into a technical backbone enterprise in the high-end nanomaterials industry. In 2008, the company has invested 0.45 billion yuan to expand the production capacity of whisker carbon nanotubes, and this whisker carbon nanotube powder project will achieve an annual production capacity of 300 tons.
The R & D center of KELAIWEI company received good news again. The planning department of KELAIWEI company heard that our company has established technical cooperation with Professor Zhang Meiyun, an industry expert from Shaanxi University of Science and Technology. KELAIWEI company strongly supports and pays attention to Professor Zhang's research and development. KELAIWEI Nano Carbon Material Co., Ltd. insists on keeping close cooperation with scientific research institutions, strengthening communication, using technology to enhance our company's competitiveness, and using technology to give back to the society, promote the rapid development of human society.
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.
An automobile manufacturer in the North developed a matching electric steering wheel for its new model, which needs far infrared paper products. The far infrared paper produced by KELAIWEI company has strong flexibility, strong acid and alkali resistance, and strong water resistance, more importantly, the electrothermal conversion efficiency of far infrared paper produced by KELAIWEI company is as high as more than 99.95%, and the customers are very satisfied. They have established a long-term cooperative relationship with our company to make carbon nanotubes.
After more than 20 years of research, the technology center of KELAIWEI company has been able to manufacture ultra-high purity whisker carbon nanotubes with a purity of 99.95%. Henan KELAIWEI carbon nanotube material Co., Ltd. and many high-end battery manufacturers at home and abroad have found in practical application research that whisker carbon nanotube is a very ideal conductive additive for positive and negative electrode materials of lithium batteries, it can effectively improve the battery life and capacity.
