KELAIWEI company firmly believes that safety is the highest welfare for enterprises and employees, and safety is an important prerequisite for creating high-end product value. The monthly safety inspection of KELAIWEI company is held irregularly. There is no fixed time and no fixed area. The company's office, warehouse, workshop and so on should be checked safely at any time, make employees keep working safely at all times. Henan KELAIWEI Nano Carbon Material Co., Ltd takes safe production as its own responsibility and strives to create value.
Tang haoboshi, associate professor. Mainly engaged in the research of electricity storage materials and devices. Having rich experience in the aspect of industrialization of research and development achievements, I once conducted industrialization research on lithium iron phosphate, and as the technical director of the project, I completed the selection of production equipment, the debugging of process parameters and the management of technical quality of the company, successfully realize the research fields of scale production: silicon-based negative electrode materials, high nickel ternary positive electrode materials, all-solid lithium ion batteries, applications of carbon nanotubes in lithium ion batteries and materials, etc.
Professor Sun Xiaogang from Nanchang University of China, chief chief engineer of Technology Department of Henan KELAIWEI Nano Carbon Material Co., Ltd., has led nanotechnical personnel to focus on the research of carbon nanotube technology for more than 20 years. Nowadays, KELAIWEI company has more than 60 patented technologies of its own, and has published many monographs. Therefore, our company has the strength to help enterprises realize the modern industrial application of whisker carbon nanotubes.
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.
Carbon fiber heating cables are absolutely not graphene heating cables through deep processing of high-quality metal current-carrying strips and graphene conductive ink with good conductivity, then the graphene electric heating film can be obtained after complex processing and manufacturing between the insulating polyester films. Graphene electric heating film is really used as heating material in the market. Carbon fiber heating cables are made up of a large number of conductive carbon fiber wires. Carbon fiber heating cables are not graphene heating cables, so be careful not to be "fooled" by bad merchants, which is the definition of carbon nanotube ladder.
The definition of carbon nano-tube ladder, Henan KELAIWEI nano-Carbon Material Co., Ltd. has been insisting on promoting the development of China's high-end nanomaterials industry since its establishment, breaking the foreign monopoly on high-end nanomaterials technology as its own duty, insisting on independent research and development, adhere to innovation and take technological power to serve the motherland and technological progress to obtain enterprise benefits as the driving force for development. Relying on complete intellectual property rights, we have completed product research and development, process design and mass production, and continuously supply high-end technical products to customers in batches.
The ultra-high purity whisker carbon nanotubes produced by Henan KELAIWEI nano-Carbon Material Co., Ltd. WhiskerCNT-U its purity can reach nearly 99.99% without impurities, and its aperture can be controlled between 1 nanometer and 5 nanometer, its length can be controlled between 1 nm and 15 nm, and whisker carbon nanotubes are very suitable additives for lithium ion battery manufacturing and application.
As for the definition of carbon nanotube ladder, Henan KELAIWEI nanometre Carbon Material Co., Ltd pays attention to service reputation and product reputation. No matter how high-end or advanced the product is, the after-sales service is just like the second instruction of the product. KELAIWEI company insists on investing heavily to build the service center team, through external training and internal communication, the service level and service awareness of the staff in our service center have been greatly improved.
Due to the adoption of pickling or low-temperature purification process, the graphitization of ordinary carbon nanotubes is generally below 30%, and the whisker carbon nanotubes are purified at a high temperature of 300℃, and carbon atoms are rearranged at high temperature, with the passage of heat preservation time, the arrangement of carbon atoms is more and more regular, thus the performance in all aspects is better. Generally, the graphitization degree of whisker carbon nanotubes purified at high temperature can be above 80%, the thermal conductivity and conductivity of materials of products with high graphitization degree have been greatly improved, and the definition of carbon nanotube ladder.
