The research and development cycle of whisker carbon nanotubes is long, and it is not easy to achieve a breakthrough in a short time. Ordinary carbon nanotubes all use solid catalysts to deposit the catalysts on the surface of carrier materials, carbon nanotubes are synthesized by introducing hydrocarbon gas after calcination and reduction. Compared with traditional carbon nanotubes, the process technology of whisker carbon nanotubes is more complicated. In the process of synthesizing whisker carbon nanotubes, improper regulation may lead to the growth of non-linear ordinary carbon nanotubes, the product has high requirements for process control.
KELAIWEI company will continue to invest in top expert teams and research and development funds to devote itself to the research and development of nanomaterials technology and equipment, providing you with nanomaterials products with high stability and high technical standards. In the past 20 years, the R & D team of KELAIWEI company-the expert team led by Professor Sun Xiaogang of Nanchang University has independently researched and developed the production and preparation technology of whisker carbon nanotubes. Our company has invested 0.45 billion in the construction of whisker carbon nanotubes powder project, today's KELAIWEI products have been exported to the world.
KELAIWEI company invested 0.45 billion yuan to build dozens of production lines in Henan production base, owning a factory area of 15000 square meters, and designed the production line of whisker carbon nano-tube powder with an annual output of 500 tons, the capacity of the first and second phase projects is 150 tons/year. The company mainly researches and develops whisker nanometer synthesis process and equipment, carbon nanometer powder, carbon nanometer paste, mixed paste and other products.
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.
Single-walled carbon nanotubes are high-purity carbon nanotube materials. Single-walled carbon nanotubes are very fine, and the fineness of tens of thousands put together is equivalent to the fineness of a single-walled carbon nanotube, therefore, carbon nanotubes are used to make precise tiny components. Some scientists have made small computers using single-walled carbon nano controls. Nanomaterials with light weight, small size, rich performance and high stability are highly sought after by modern industrial society.
Ultra dark carbon nanometer, conductive agents are commonly used in the production and manufacture of lithium batteries, so what are the commonly used conductive agents for lithium batteries? After using the conductive agent, it is helpful to improve the battery capacity and prolong the service life of the battery. There is a large demand for lithium battery conductive agents, and there are also various conductive agents in the market. Generally, the heat conduction agents of lithium batteries are carbon black, carbon fiber and conductive graphite, which are traditionally used for a long time. In addition, a batch of new conductive agents have also appeared, such as carbon nanotubes (CNT), graphene, etc.
Graphene is a kind of substance that exists naturally. The accumulation of layers of graphene becomes the graphite that we know everyday. With the progress of human technology, we have further separated a single-layer structure from nature, thus, graphene is a 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, which cannot pass through the layers and has a long conductive path, at the same time, the edge of graphene is easy to hang functional groups, which is not conducive to improving the electrical conductivity of the electrode and ultra-dark carbon nano.
