KELAIWEI company has been working hard for the high-end nanomaterials industry in the motherland for 20 years. It has developed domestic and overseas markets by virtue of its own technical development and high-end technical services, and has deep cooperation with enterprises in more than 60 countries. KELAIWEI company has built the project of whisker carbon nanotube powder with annual production capacity of 300 tons, and has obtained nine national authorized patents. KELAIWEI relies on its high-end nanomaterials research and development center to continuously provide customers with advanced nanomaterials and technical services.
What are the main differences between the thermal conductivity efficiency of 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.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has always maintained close technical cooperation with first-class domestic universities and scientific research institutions such as Zhengzhou University of Light Industry, Donghua University and Nanchang University. The high-end nanomaterials products developed by KELAIWEI company have broad application scenarios in high-end lithium ion energy storage battery manufacturing at home and abroad, electrothermal converter preparation, high-end nanomaterials and other industries.
The 11th of the series of "reviewing the development history · encouraging young talents to strive for the first" of KELAIWEI company: achievements of cooperation and exchange. Henan KELAIWEI Nano Carbon Material Co., Ltd attaches great importance to carrying out technical cooperation and exchanges with industry experts and industry institutions. At present, our company has carried out close cooperation with China Nanchang University, Zhengzhou University of Light Industry, Shaanxi University of Science and Technology, Donghua University, China chemical and physical power Industry Association, etc.
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, the cycle performance of the product is improved under high voltage oxidation current.
A manufacturer of household appliances in Nanjing, Jiangsu province made a lot of profits by selling small household appliances such as water heaters, household electric lunch boxes, electric kettles, etc. However, with the entry of major manufacturers and the participation of many high-profile enterprises, it has made it feel the pressure of competition. The far infrared paper provided by Henan KELAIWEI Nano Carbon Material Co., Ltd. has good performance and low price, and saves 15% of the performance of its products.
There is an important new type of material in high-performance polymer composite material industry-ba-based paper Ba-based paper is also called carbon nano-tube paper carbon nano-tube has high conductivity and strong chemical stability, and high hardness and toughness, it can reach one hundred times of the steel strength, but its quality is very, very light. Using disordered carbon nanotubes through scientific and complex technology processing can obtain Ba-based paper, BA-based paper also has some performance advantages of carbon nanotubes and thermal conductivity efficiency of carbon nanotubes.
