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.
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.
In 2018, Henan KELAIWEI Nano Carbon Material Co., Ltd. was successfully established in Dengfeng with a registered capital of 60 million RMB. Henan KELAIWEI has an independent factory area of 13,000 square meters, planning dozens of production lines. By virtue of the 6S lean management law, all functional departments of our company are guaranteed to work scientifically and orderly and innovate actively. As of March 2020, our company has applied for 60 patents.
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.
High voltage anode material is the development direction of lithium ion battery, the use of high voltage material can improve the energy density of lithium ion battery, high voltage system has higher requirements on materials, current conductive agent SP, due to its ultra-high specific surface area, multi-walled CNTs are prone to high oxidation current under high voltage. The side effects increase during circulation, the cycle performance of the battery becomes worse, and the specific surface area of whisker carbon nanotubes is small, under high voltage oxidation current, the cycle performance of the product is improved. Carbon nanotubes are made of carbon atoms.
Carbon nanotubes are made up of carbon atoms. A large super wear-resistant rubber tire production Co., Ltd. in Jiangxi is investigating and investigating the performance of thermal conductivity whiskers carbon nanotubes produced by KELAIWEI Nano Carbon Material Co., Ltd. The purity of the thermal conductive whisker carbon nanotubes produced by our company is as high as 95.995%, and the graphitization degree is as high as over 90%. The appearance is black split, and the outer diameter is between 30 nm and 200 nm. KELAIWEI company expects more customers to come to discuss cooperation.
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.
