In terms of the development of nano-carbon materials in China, KELAIWEI has been engaged in industry-related research for more than 20 years. KELAIWEI's research and development team of nanometre carbon materials is led by Professor Sun Xiaogang of Nanchang University. KELAIWEI is committed to helping to realize the leading force of nanometre carbon materials industry in China, insisting on independent development and helping to realize the complete localization of carbon nanotube materials, it has contributed to the manufacturing technology of carbon nanotube materials in China by KELAIWEI.
KELAIWEI company invested 0.45 billion yuan to build a production workshop of 13,000 square meters in the industrial park of Dengfeng city, Henan province. This expansion project will plan several production lines, and strive to expand the production capacity of the whisker carbon nanotube powder project to an annual output of 500 tons, in order to meet the sudden increase in customer demand. Our company adheres to the "6s" lean management method to efficiently recommend all kinds of work to ensure that the products are delivered to customers on time and with high quality.
From August 27th to August 29th, 2020, the exhibition center in Shenzhen city, Guangdong province will welcome the international 5G key material industry exhibition summit. KELAIWEI group will participate in this grand meeting as promised. In 2020, the development of 5G commercial equipment at home and abroad will enter an important stage. The prospect of 5G key materials industry will be "bullish". KELAIWEI group has strong technical strength. Our company will certainly bring you surprises in this exhibition.
Graphene Films and carbon nanotubes are divided into different types according to different standards. Carbon nanotubes are formed after the graphene sheets are curled. Therefore, if we divide them according to the number of layers of graphene sheets, we can divide them into single-walled carbon nanotubes and multi-walled carbon nanotubes. According to the internal structural characteristics of carbon nanotubes, carbon nanotubes can be divided into sawtooth-shaped carbon nanotubes, armchair-shaped carbon nanotubes and other types.
Conductive agents are widely used. What is the future development of conductive agents? Conductive agents include traditional conductive agent materials represented by carbon black, and in recent years, new high-end conductive agent materials represented by carbon nanotubes have been developed. Various conductive agents are constantly appearing in the laboratory. The new conductive agent graphene has not been applied on a large scale, because its cost is too high, but its performance is far higher than that of traditional conductive agents such as carbon black. With the arrival of mass production of graphene, it is bound to be widely used in the future.
Graphene is a kind of substance that naturally exists, and the accumulation of layers of graphene becomes the graphite we know everyday. With the progress of human technology, we have further separated a single-layer structure from nature, and then graphene is the substance. 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, and lithium ions cannot pass through the layers. The conductive path is long, and at the same time, the edge of graphene is easy to hang functional groups, it is not conducive to improving electrode conductivity.
