In 2020, KELAIWEI had been deeply engaged in the research and development and preparation of nanomaterials for 20 years. Our company fully owns independent intellectual property rights of relevant industries and has applied for 106 patents (including 9 national authorized invention patents and 2 international PCT patents). Our deep cooperation customers have spread all over the world (more than 60 countries such as Asia, America, Europe and Africa). All the staff of KELAIWEI are forging ahead and looking forward to establishing a deep partnership with you.
What are the main differences between carbon nanotubes and carbon nanofibers? Henan KELAIWEI Nano Carbon Material Co., Ltd. has published two monographs on carbon nanotubes and applied for more than 60 patents. The purity of the prepared whisker carbon nanotubes has reached 99.99%. Carbon nanotubes are carbon materials with hexagonal connection structure, while carbon nanofibers are wire-mounted materials. Fibers with a diameter of less than 1000 nanometers are all nanofibers.
KELAIWEI company invested 0.45 billion yuan to build a production workshop of 13,000 square meters in the industrial park of Dengfeng city, Henan province. This expansion project will plan several production lines, and strive to expand the production capacity of the whisker carbon nanotube powder project to an annual output of 500 tons, in order to meet the sudden increase in customer demand. Our company adheres to the "6s" lean management method to efficiently recommend all kinds of work to ensure that the products are delivered to customers on time and with high quality.
The fourth of the series of "reviewing the development history · encouraging young talents to strive for the first" of KELAIWEI company: 2012 memorabilia. Professor Sun, the technical leader of KELAIWEI company, has led the technical team to develop mass production equipment and improve purity since the synthesis of whisker carbon nanotubes, and finally developed the second generation whisker carbon nanotubes production equipment, the output of our company's whisker carbon nanotubes reached 0.5kg/h.
The density of double-walled carbon nanotubes, unmanned aerial vehicle batteries have high requirements for lithium ion batteries, which need to be discharged in a short time at high magnification, and whisker carbon nanotubes are added to the lithium ion batteries of unmanned aerial vehicles as conductive agents, the rate performance of the battery is improved, the internal resistance is reduced, the power output is larger, the cycle performance is improved, the flight time of the unmanned aerial vehicle can be longer, and the service life of the battery is longer, at present, KELAIWEI has cooperated with Company C, and the product performance is equivalent to that of Japan's Showa electrician, and the density of double-walled carbon nanotubes.
Recently, the sales volume of multiplied whisker carbon nanotubes of Henan KELAIWEI nano-Carbon Material Co., Ltd. has soared and the inventory is tight. This is due to a large order of our products from a foreign trade company in Shanghai, which is used to produce carbon nanotube conductive paper. The multiplied whisker carbon nanotubes produced by Henan KELAIWEI Nano Carbon Material Co., Ltd have excellent performance. Its purity is as high as 95.99%, so the content of metal impurities is very small, the stability at high magnification is more prominent, and the performance is better in low temperature environment.
The higher the purity of whisker carbon nanotubes and the less metal impurities are, the higher the purity can be selectively applied in the manufacturing field of high-end power lithium batteries. KELAIWEI company found that because the ultra-high purity whisker carbon nanotubes have very high adsorption force on electrolyte, therefore, whisker carbon nanotubes with very little impurity content of ultra-high purity can be used as the anode material and anode material additive of lithium ion battery.
