Professor Sun Xiaogang's long-term research on carbon nanotubes includes the synthesis, modification and filling of carbon nanotubes and the application of carbon nanotubes in the fields of electromagnetic shielding, wave absorption, lithium ion batteries and composite materials. Chairman and general manager of Jiangxi KELAIWEI Nano Carbon Material Co., Ltd. In 1999, it began to produce carbon nanotubes and provided them to the whole world. In 2000, it successfully developed a 5kg carbon nanotube device per day. In 2001, it established Nanchang Sun nanotechnology Co., Ltd. and served as the chairman and CEO, the company is one of the first several companies in the world to industrialize the production of carbon nanotubes (at that time there were only 7 companies in the world that could provide carbon nanotubes products), and the production of carbon nanotubes reached the ton level, users all over the world.
Compared with carbon fiber heating and carbon crystal heating, Henan KELAIWEI Nano Carbon Material Co., Ltd is an international advanced research, development, design and development of high-end nano materials and process equipment, manufacturer our company has established Jiangxi KELAIWEI company and Henan KELAIWEI company respectively. KELAIWEI company has completely independent intellectual property rights, focusing on high-end nanomaterials technology research and development, process design, equipment manufacturing, technical service is a high-tech manufacturer integrating carbon fiber heating and carbon crystal heating.
Henan KELAIWEI nano-Carbon Material Co., Ltd. is one of the first enterprises to research and develop the synthesis of whisker-like carbon nanotubes in China, especially in the field of production and preparation of whisker-like carbon nanotubes, possessing 9 national invention patents, it has issued and published two books on carbon nanotubes, applied for more than 60 patents and is increasing year by year. It has great technical advantages in the field of whisker-like carbon nanotubes.
Production skills are important, safety skills and safety awareness are more important. No production can be performed without security guarantee. Henan KELAIWEI Nano Carbon Material Co., Ltd. regularly carries out staff safety production skills training. KELAIWEI company firmly believes that production safety training is responsible for employees, customer products, the company and the basic requirements of the enterprise's production safety responsibility.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has learned that the market prospect of carbon nanotube materials is very broad. Carbon nanotube materials have excellent conductivity, optical properties, high strength and high toughness (which can be 100 times that of steel). Therefore, carbon nanotube materials are widely used in automobile manufacturing, semiconductor product production, building template materials, battery manufacturing and other fields.
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.
Due to its special structure, the thermal conductivity of the product can reach 3000w/(m · K) under ideal conditions, but ordinary carbon nanotubes will introduce a large number of defects in the production process, causing the bending of carbon nanotubes, the crystal structure of carbon nanotubes is damaged, and the thermal conductivity is affected. The whisker carbon nanotubes belong to linear structure, and the crystal structure of carbon nanotubes can be retained to the maximum extent, the thermal conductivity of the product can be brought into play to a greater extent and has a very broad space in the field of 5G heat dissipation.
