Since its establishment, KELAIWEI company has been committed to the research and development, processing, manufacturing and sales of carbon nanomaterials technology and preparation equipment. The R & D engineers, management personnel and sales personnel of KELAIWEI company come from university research institutions and large enterprises. KELAIWEI company's cooperative customers spread all over over 60 countries and regions such as Europe, America, Asia and Africa. KELAIWEI motivates himself to become the R & D and manufacturing expert of advanced carbon nanomaterials at home and abroad.
Brief introduction of carbon nanotubes. Carbon nanotubes are a kind of nanomaterials, and they also have the name: Pakistan tube. Carbon nanotubes are composed of carbon atoms with hexagonal structure layer by layer, and the distance between each layer of carbon atoms is about 0.34 nanometers. It can't be seen by naked eyes, and its weight can't be felt by hands. Carbon nanotubes have very rich properties, such as conductivity, heat conduction, stable structure, acid resistance, alkali resistance and water resistance......
With the high adsorbability of carbon nanotube fiber, KELAIWEI nano-carbon material company has absorbed a group of like-minded professional R & D talents in high-end nano-material industry. High-end nanomaterials are different from ordinary products and have high technical requirements. The strong power of technological research and development and innovation is the fundamental guarantee for the survival, development and expansion of KELAIWEI nanocaterials company. KELAIWEI people's courage to innovate in technology and the spirit of keeping improving in products have made many enterprises choose "KELAIWEI creation".
The seventh of the series of "reviewing the development history · encouraging young talents to strive for the first" of KELAIWEI company: Events of 2018. Key breakthrough in the development history of KELAIWEI company: the production line of whisker carbon nanotubes with an annual output of 30 tons has been successfully developed. KELAIWEI company's whisker carbon nanotubes business ushered in a technological breakthrough, which greatly increased the market supply of KELAIWEI company's whisker carbon nanotubes.
Improving energy density is the current difficulty and pain point of lithium ion battery. Silicon carbon negative pole is the future development direction. During the charging and discharging process of lithium ion battery, the material will expand by 200 ~ 400%, the cycle performance of the battery is poor. Because of the use of grinding process to make the paste, the length of the carbon nanotube conductive agent is 0.5 ~ 1μm, and the length of the whisker carbon nanotubes is 6μm, when it is used as the conductive agent, it can still maintain the conductive network when the volume expands. KELAIWEI cooperates with Company B on the silicon carbon negative pole, and the circulation performance is improved.
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.
Carbon nanotubes are very useful in the field of batteries high-end batteries must have a long life, high capacity and other characteristics high-end battery manufacturing requires higher material performance carbon nanotubes have excellent conductivity and very high aspect ratio structural characteristics, therefore, the whisker carbon nanotubes produced by Henan KELAIWEI Nano Carbon Material Co., Ltd. are being used as an important additive of positive and negative electrode materials in the high-end battery manufacturing industry, and the high adsorbability of carbon nanotube fibers.
