KELAIWEI nano carbon material company has established Jiangxi company (Jiangxi KELAIWEI Nano Carbon Material Co., Ltd.) and Henan company (Henan KELAIWEI Nano Carbon Material Co., Ltd.). KELAIWEI company is mainly engaged in the production and application research of whisker carbon nanotubes and the research and development of preparation equipment. Our company insists on independent innovation and research and development of carbon nano-tube materials, breaking foreign monopoly and revitalizing the cause of carbon nano-tube materials in our motherland.
What are the manufacturing methods of carbon nanotubes? Since the discovery of carbon nanotubes, the research on carbon nanotubes has never stopped. Carbon nanotubes have complex and excellent properties, which are both conductive and conductive, very thin but very hard, compared with a hundred times of steel hardness, carbon nanotubes are widely used, so various preparation methods have also been invented. Common production methods include arc method, catalytic thermal decomposition method, hydrothermal method and chemical vapor deposition, etc., carbon nanotubes temperature-sensitive discoloration.
KELAIWEI nano-carbon material company has invested 0.45 billion in the construction of whisker carbon nano-tube powder engineering, with the first-phase engineering capacity reaching 150 tons and the second-phase engineering design capacity reaching 150 tons, finally, the production capacity of the whisker carbon nanotube material of KELAIWEI company reached 500 tons per year. The income of this whisker carbon nanotube powder project is expected to reach an annual output value of about 0.5 billion yuan. KELAIWEI's products have been exported to more than 60 countries such as Europe and America.
Henan KELAIWEI Nano Carbon Material Co., Ltd. Uses carbon nano paste as conductive and heat conducting additive, and has achieved key breakthrough in the research of applying to modern equipment manufacturing. Additives will be used in all walks of life. Unlike traditional conductive and thermal conductive additives, carbon nanometer paste has better conductive and thermal conductivity. For example, the conductivity of carbon nanotubes is more than 10% better than that of traditional carbon black products.
The energy storage lithium ion battery has higher requirements on the cycle performance of the lithium ion battery, and the ratio of the energy storage lithium ion battery is small. When the lithium ion battery has a long cycle, the materials will expand and pulverize at the end of the cycle, the battery will have a large attenuation. Because of its large length-diameter ratio and long fiber length, the whisker carbon nanotubes are generally more than 6 μm, and the battery can still maintain the conductive network in the late cycle, the cycle performance of the battery is improved.
Henan KELAIWEI Nano Carbon Material Co., Ltd. Devotes itself to the research and product manufacture of high-performance far infrared paper the far infrared paper is widely used in the field of thermal insulation. An electric heater manufacturer in Heilongjiang is very interested in it after contacting the far infrared paper of KELAIWEI company, let KELAIWEI company provide some samples for product trial, and finally find that the thermal conductivity and service life of the electric radiator using our products are obviously better than other products, and the temperature-sensitive color-changing of carbon nanotubes.
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.
