KELAIWEI company has invested 0.55 billion yuan to carry out deep cooperation with the research and development team led by Professor Sun Xiaogang of Nanchang University in China for a long time. And invested 0.45 billion yuan successively in Henan to build the first phase of whisker carbon nano-tube powder project and the second phase of whisker carbon nano-tube powder project, which made the production capacity of whisker carbon nano-tube powder of Henan KELAIWEI nano-Carbon Material Co., Ltd achieve qualitative improvement, up to 300 tons/year.
Brief introduction of carbon nanotubes. Japanese physicist Yoshima Yoshino was the first to discover carbon nanotubes. Carbon nanotubes are tubular carbon molecules. Carbon nanotubes are very, very thin and cannot be seen simply by eyes, because tens of thousands of carbon nanotubes are put side by side, it may not be as thick as a hair. According to the number of pipe layers, it can be divided into single-walled carbon nanotubes and multi-walled carbon nanotubes.
Jiangsu carbon nanotubes, KELAIWEI nanometer carbon material is a large-scale manufacturing enterprise focusing on the research and development of high-end nanomaterials technology, industrial production, domestic and foreign trade sales and high-end NanoMaterials Technology Services. Henan KELAIWEI Nano Carbon Material Co., Ltd. cooperates with domestic scientific research institutions in colleges and universities to establish a capable technical research team, providing strong technical support for the product quality and technological innovation of our company.
Jiangsu carbon nanotubes, Henan KELAIWEI nano-Carbon Material Co., Ltd. uses carbon nano-slurry as conductive and heat conducting additive, and it is applicable to the research of modern equipment manufacturing and has achieved key breakthrough. Additives will be used in all walks of life. Unlike traditional conductive and thermal conductive additives, carbon nanometer paste has better conductive and thermal conductivity. For example, the conductivity of carbon nanotubes is more than 10% better than that of traditional carbon black products.
High capacity lithium ion battery is the negative electrode material of lithium ion battery, which requires high capacity. At present, silicon carbon negative electrode material is generally used, and silicon carbon negative electrode will generally expand to a large extent when used, resulting in poor cycle performance of the battery, taking advantage of the length advantage of whisker carbon nanotubes, the conductive network can still be maintained when the silicon carbon negative electrode material expands, and the cycle performance of the battery is improved. At present, KELAIWEI is cooperating with X company in developing the negative capacity to increase the capacity and circulation performance of the negative.
A new energy automobile power lithium battery manufacturing company in Sichuan is looking for a batch of power whisker carbon nanotubes which are applied to power lithium battery manufacturing with extremely low metal impurity content. The supply is required to be completed in the current month. Henan KELAIWEI carbon nanotubes Material Co., Ltd. can completely meet the needs of the other side.
