After more than 20 years of research and development, KELAIWEI company has mastered the core technology. It has nine national patents, two international PCT patents and more than 40 technical papers, the publication of two monograph on carbon nanotubes laid the foundation of our company's dominant position in technology in the industry technological progress benefited from our leadership's continuous investment in research and development funds and Professor Sun Xiaogang's 20-year special technical research and development of carbon nanotubes in KELAIWEI company stand alone in the world, looking forward to your joining and cooperation, calcined carbon nanotubes in the air.
Fundamentally speaking, are there any essential differences between common carbon nanomaterials and graphene? Graphene is a thin film material. The thickness of graphene is only one carbon atom. The mechanism of graphene is fundamentally different from that of common carbon nanomaterials. Graphene, fullerene nanomaterials, carbon nanotube nanomaterials and so on, these carbon nanomaterials are different in structure and form, it can be said that the physical properties of graphene and carbon nanomaterials are still different.
Advanced technology, high-quality products and other advantageous resources in the industry can be combined with efficient enterprise management to produce high-quality products. At the beginning of the establishment of clevey nano carbon material company, an efficient management system was established through "lean management law. The production of products is managed "strictly" according to the standards that exceed ISO9001 and IATF16949 quality management system rules, so as to ensure that the quality of the products obtained by customers is superior and they can be used safely.
KELAIWEI Nano Carbon Material Co., Ltd. invested 0.55 billion yuan in 2017 and 2018 to build production research and development centers: Jiangsu KELAIWEI production research and development center and Henan Dengfeng KELAIWEI production research and development center. KELAIWEI Nano Carbon Material Co., Ltd. has recently expanded the production of whisker carbon nano-tube powder in Henan's 13,000-square-meter production base, with an annual output of 300 tons.
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.
Calcined carbon nanotubes in the air, a manufacturer of far infrared electric heating room in Henan, recently developed a new product. In order to reduce the use of thermal conductivity materials in order to save space, other parts are added, far infrared paper is urgently needed to replace some materials, but the company has strict requirements on the working temperature of far infrared paper, requiring that far infrared paper still has super stability within 120 degrees, the suppliers in the provinces near the company were not suitable, so they finally chose our products (the working temperature was less than 300 degrees).
With the development of power and energy equipment, high-end commercial energy storage battery manufacturers are very concerned about the application of superconducting additives. The whisker carbon nanotubes with very high purity and almost no impurities manufactured by Henan KELAIWEI Nano Carbon Material Co., Ltd can be applied as conductive additive of positive and negative pole material of power lithium battery, which can prolong the service life of lithium battery, and increase its capacity and other characteristics.
