Whisker carbon nanotubes are directly added with powder when they are used as conductive agents for lithium ion batteries. The powder has good processing performance and can be used without process conductive paste. There is no abnormality in processing performance during the process, powder cannot be used by ordinary carbon nanotubes, and cannot be dispersed by using powder in the process of homogenization. Particles are easy to appear in the process of homogenization, and the performance of materials cannot be brought into full play. Therefore, conductive paste needs to be made separately for use, conductive paste is prone to the problem of uneven solid content, which will have a great impact on the consistency of the battery.
Carbon nanotubes are important industrial additives due to their excellent conductivity. They can be used as antistatic plastics when added to composite materials. Because of their linear structure, they have the characteristic of easy dispersion, high electrical conductivity can be achieved with low addition amount added to the composite material. At present, the surface resistance value of the prepared whisker carbon nanotubes can reach 101-109 with the addition amount of 1-5% wt, at present, KELAIWEI is cooperating with Z Research Institute to develop the installation technology of antistatic plastic and far infrared carbon crystal electric heater.
Since its establishment, KELAIWEI Henan and Jiangxi research and development center bases have insisted on relying on technological breakthroughs to improve the competitiveness of nanomaterials industry products in our country, and have made efforts to break the blockade restrictions imposed by some foreign countries on high-end materials products in our country. KELAIWEI efficiently coordinates capital, technology research and development, workshop and other company resources, focuses on strengthening internal and external technology exchanges, and works closely with efficient industry experts in order to make a new breakthrough in KELAIWEI.
After the establishment of Henan KELAIWEI Nano Carbon Material Co., Ltd, the "big action" continued. KELAIWEI company spent 0.45 billion yuan to invest in the whisker carbon nanotube powder project, which is expected to generate 0.5 billion yuan per year, two phases of the project will be launched in the 13,000-square-meter factory area of Dengfeng production base of KELAIWEI company. The design capacity of each phase of the project will reach 150 tons/year, installation technology of far infrared carbon crystal electric heater.
Carbon nanotubes are divided according to different standards. Different kinds of graphene sheets are curled to form carbon nanotubes. Therefore, if we divide them according to the number of layers of graphene sheets, then carbon nanotubes can be divided into single-walled carbon nanotubes and multi-walled carbon nanotubes. If according to the internal structural characteristics of carbon nanotubes, carbon nanotubes can be divided into sawtooth-shaped carbon nanotubes, armchair-shaped carbon nanotubes and other types, far infrared carbon crystal electric heating installation technology.
After more than 20 years of hard Development, Henan KELAIWEI Nano Carbon Material Co., Ltd has owned independent intellectual property rights of production and processing technology and equipment in the field of whisker carbon nanotubes. KELAIWEI company has realized the industrial mass production of high-performance whisker carbon nanotubes, and our company has reached cooperation with more than 100 enterprises at home and abroad. As long as there is demand for whisker carbon nanotubes products in the market, KELAIWEI company will appear.
Whisker carbon nanotubes have higher crystallization and purity than traditional carbon nanotube materials, and are easier to disperse. Therefore, the ultra-high purity whisker carbon nanotubes can improve the cycle performance and magnification performance of lithium batteries better than traditional carbon nanotubes, so they are increasingly Selected as additives by high-end lithium ion battery manufacturers. Henan KELAIWEI Nano Carbon Material Co., Ltd. has made abundant research achievements in the field of whisker carbon nanotubes.
What are the classification of Carbon Nanotubes? Carbon nanotubes are composed of several layers of hexagonal carbon atoms. The Axis size is only micrometer, the two ends are closed, and the radial size is only nanometer, according to the difference of carbon six-side type along the axis direction in the industry, carbon nanotubes are classified as follows, namely, Sawtooth carbon nanotubes, armchair carbon nanotubes and spiral carbon nanotubes.
