KELAIWEI is a high-tech enterprise of carbon nanomaterials. Since the establishment of KELAIWEI, relying on the technical accumulation of over 20 years by Professor Sun Xiaogang's expert team of Nanchang University, KELAIWEI has actively explored the nanomaterials market at home and abroad. In 2008, Professor Sun's team has successfully synthesized whisker-like carbon nanotubes, in 2013, our company has achieved an annual production capacity of 30 tons, and now we have invested 0.45 billion to build a project of 300 tons of whisker carbon nanotube powder.
Brief introduction of graphite conductive agent and carbon nanotube (CNT) conductive agent. The application of graphite conductive agent in lithium batteries can obviously improve the conductivity of lithium ions and electrons. CNT conductive agents are often used to make high-end 3C digital batteries. Almost half of high-end digital batteries can see the shadow of CNT conductive agent. The use of conductive agent is very important for lithium battery manufacturing. Conductive agent can ensure that the battery electrode can maintain a good charging and discharging performance state continuously.
Since its establishment in 2018, Henan KELAIWEI Nano Carbon Material Co., Ltd has paid great attention to the development of high-end nano material technology and the formation of talent team. In order to realize the scientific research goal of clevere company, our company has maintained deep cooperation with many domestic universities and scientific research institutions. For example, the team of Professor Sun Xiaogang from Nanchang University, Donghua University, Zhengzhou University of light industry and other universities continuously input product technology and talent strength for our company.
The technological achievements of Henan KELAIWEI Nano Carbon Material Co., Ltd are continuous. Under the leadership of Professor Sun, the chief engineer of KELAIWEI's technical team, once again obtained the technical patent in the synthesis of whisker carbon nanotube materials. It is reported that the technical patent number obtained this time is "ZL201210304345.7". The technical name is "automatic and continuous production of whisker carbon nanotubes synthesis device".
In China's carbon nanotube company, the utilization rate of active materials in lead-acid battery is low, the energy density is relatively small, and the cycle performance is poor. Carbon whisker nanotubes are added to the negative pole of lead-acid battery, it can greatly improve the conductivity of the polar plate and improve the consistency of the lead-acid battery. Because it is a linear conductive agent, it can still maintain the conductive network in a long cycle, so the cycle characteristics of the battery can be improved. Moreover, due to the addition of whisker carbon nanotubes, the charging and discharging depth of lead-acid battery can be appropriately improved, and the energy improvement can be improved. KELAIWEI and Y Company have conducted in-depth cooperation in the field of lead-acid.
A lithium battery research and development company in Jiangsu needs 100 grams of whisker carbon nanotubes, which requires absolute low-value metal impurity content and can be applied to high-rate batteries and power batteries. Henan KELAIWEI carbon nanomaterials Co., Ltd. can provide power whisker carbon nanotubes with purity as high as 95% or more. Its graphite hardness is above 65%, the residual metal is less than 100ppm, and the average spacing between carbon tubes is less than 0.3384 nanometers.
China's carbon nanotube companies, carbon nanotubes are very useful in the battery field. High-end batteries must have the characteristics of long life and high capacity. High-end battery manufacturing requires higher material performance. Carbon nanotubes have excellent conductivity and structural characteristics of very high aspect ratio, 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.
