Tang haoboshi, associate professor. Mainly engaged in the research of electricity storage materials and devices. Having rich experience in the aspect of industrialization of research and development achievements, I once conducted industrialization research on lithium iron phosphate, and as the technical director of the project, I completed the selection of production equipment, the debugging of process parameters and the management of technical quality of the company, successfully realize the research fields of scale production: silicon-based negative electrode materials, high nickel ternary positive electrode materials, all-solid lithium ion batteries, applications of carbon nanotubes in lithium ion batteries and materials, etc.
Henan KELAIWEI Nano Carbon Material Co., Ltd. is an international advanced manufacturer of research, development, design and production of high-end nano materials and process equipment. Our company respectively established Jiangxi KELAIWEI company and Henan KELAIWEI company. KELAIWEI company has completely independent intellectual property rights, focusing on high-end nanomaterials technology research and development, process design, equipment manufacturing, technical services and so on.
Henan KELAIWEI Nano Carbon Material Co., Ltd. is one of the well-known enterprises in the high-end nano materials industry KELAIWEI owns 2 international PCT patents, 9 national patents, more than 40 industry papers, two monograph on carbon nanotube industry...... In the field of high-end nanomaterials, the leader of KELAIWEI company made a decision to continuously invest heavily in research and development. Our company will continue to tackle key problems, continue to break the technological monopoly of foreign industries, and contribute to the development of nanomaterials technology in our country. Carbon nanometre vacuum tube.
KELAIWEI company established itself with technology. KELAIWEI company has more than 20 years of research and development experience. In 2006, Professor Sun Xiaogang's team began the research and development of whisker nanometer. Two years later, whisker-like carbon nanotubes were developed. Five years later, the 10-ton production equipment and process development of whisker-like carbon nanotubes were completed. The industrial standard production line with an annual output of 30 tons in 2018 was put into use. KELAIWEI company has established research and development base in Jiangxi and research and development base in Henan successively.
What are the common processing and manufacturing methods for carbon nanotubes? KELAIWEI carbon nanomaterials company will give you a brief introduction. The common manufacturing methods of carbon nanotube materials include polymerization synthesis, arc discharge (currently mainly used), chemical vapor deposition (higher purity than arc discharge), glow Discharge method, solid phase pyrolysis method and laser ablation method, etc.
How is carbon nanotubes made by chemical vapor deposition? Carbon nanotube materials are widely used and have strong properties, but their production is very low and the manufacturing process is complex. Therefore, scientists have continuously improved the manufacturing methods. Chemical vapor deposition method is used to produce carbon nanotubes, and its production efficiency is still relatively high. By chemical vapor deposition, carbon-containing gases are cracked by catalysts to obtain carbon nanotubes.
Compared with graphene, the internal structure of the whisker carbon nanotubes is a linear structure, which determines that the whisker carbon nanotubes can quickly form a network structure in each application product. Graphene is generally not suitable to be used as a separate conductive agent, at the same time, flaky graphene is easy to block lithium ions in the layered direction, and lithium ions can only be transmitted through the lamellar surface. At the same time, it is easy to hang functional groups on the edge of graphene, which is not only conducive to improving electrode conductivity, but also carbon nano vacuum tube.
