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.
"Technology is the mainstay, product performance is high, and service is satisfactory" is the business philosophy that the technical staff of Henan KELAIWEI Nano Carbon Material Co., Ltd insist on implementing in the development of more than 20 years. The R & D team of KELAIWEI, led by Professor Sun Xiaogang, the top domestic nanomaterials research expert, has applied for more than 100 patents and has 9 national property rights patents. KELAIWEI pursues promoting the leapfrog development of nanomaterials with technological progress.
The technical team of Henan KELAIWEI Nano Carbon Material Co., Ltd. is one of the early domestic enterprises specializing in the technical research and development of high-end nano materials and manufacturing of industrial mass production equipment. Since its development, the technical team of KELAIWEI company, which has gone through more than 20 years, has successively applied for 9 national patents, and 2 monographs have been published. Our products have broken some technical monopolies of foreign counterparts, and went abroad and sold it abroad.
Carbon Nanofiber cnf, KELAIWEI company firmly believes that safety is the highest welfare for enterprises and employees, and safety is an important prerequisite for creating high-end product value. The monthly safety inspection of KELAIWEI company is held irregularly. There is no fixed time and no fixed area. The company's office, warehouse, workshop and so on should be checked safely at any time, make employees keep working safely at all times. Henan KELAIWEI Nano Carbon Material Co., Ltd takes safe production as its own responsibility and strives to create value.
For lithium battery manufacturing enterprises, conductive agent products are very important. Henan KELAIWEI Nano Carbon Material Co., Ltd. observed that at present, the traditional conductive agent products are mostly conductive carbon black or nano carbon fiber, etc. In recent years, a new material has emerged: carbon nanotubes. Compared with the traditional conductive carbon black, its conductivity is improved by more than 10%. KELAIWEI company is committed to the research of carbon nanomaterials and looks forward to cooperating with you.
Fundamentally speaking, are there any essential differences between common carbon nanomaterials and graphene? Graphene is a thin film material, the thickness of graphene is only one carbon atom. The structure of graphene mechanism is fundamentally different from that of common carbon nanomaterials. Graphene, fullerene nanomaterials, carbon nanotube nanomaterials, etc. Different, moreover, the form is also different. It can be said that the physical properties of graphene and carbon nanomaterials are still different, such as carbon nanofiber cnf.
Whisker carbon nanotubes are purified at high temperature with low content of metal impurities, which can be directly used in the form of powder. Ordinary carbon nanotubes use grinding technology to prepare conductive paste, during the high-speed grinding process of the equipment for preparing conductive paste, due to the collision of zircon beads, metal impurities will be generated, which will affect the self-discharge of the battery and the safety performance of the product, metal Impurities will pierce the membrane of lithium ion battery and cause short circuit of the battery. Power battery has extremely strict requirements on this index, and whisker carbon nanotubes are safer to use.
