Conductive graphite is a kind of micrometer graphite sheet. Due to its large particle size, conductive graphite cannot form enough conductive network with a very small addition amount in lithium ion battery, it cannot show good performance when added to the cathode material of lithium ion battery. Because of its small diameter, whisker carbon nanotubes have the characteristics of linear structure and long length. This characteristic determines that graphite is very suitable for application in lithium battery, heating and other fields.
The negative electrode material of lithium ion battery needs high magnification. At present, conductive graphite is usually mixed with conductive graphite. Conductive graphite belongs to large-scale conductive agent, which is not easy to realize high conductivity in low additive amount. In the manufacturing process of graphite negative electrode, with the addition of whisker carbon nanotubes, because the crystallization of whisker carbon nanotubes is generally above 70%, it has a certain lithium-embedded capacity, which can ensure a higher use ratio under the condition that the capacity is not lost, at present, KELAIWEI is cooperating with X company in developing the negative pole with high magnification to increase the magnification and capacity of the negative pole.
Henan KELAIWEI company has an expert research and development team with strong technical strength in the field of high-end nanomaterials, and independently designs production equipment and technology with full intellectual property rights. KELAIWEI company is determined to be the leader of high-end nanomaterials industry. KELAIWEI adheres to technological innovation and promotes the company's leapfrog development with technology. After more than 20 years of research and development, KELAIWEI technicians have obtained more than 100 technical patents.
Silicon carbide long crystal technology and carbon-based nanomaterials are important businesses of KELAIWEI company. KELAIWEI Nano Carbon Material Co., Ltd. Established the production base of Dengfeng city in Henan province and the production research and development base of KELAIWEI in Jiangxi province to provide high quality whisker carbon nanotube powder for major customers at home and abroad, A series of high-end and high-quality carbon-based nanomaterials, such as whisker carbon nanotube conductive paste of various specifications. The research on carbon-based nanomaterials technology KELAIWEI company will continuously add investment.
In the field of high-end lithium ion battery manufacturing, a new material is being rapidly applied, namely carbon nanotubes. Compared with the traditional electric black, the conductivity of carbon nanotubes is one tenth higher than that of the latter, and its weight is very light. It is enough to be added and used in a small amount. Compared with the traditional materials, the use of conductive materials can be reduced by 30%. Therefore, KELAIWEI company expects that the market prospect of carbon nanotubes will be bright and the market demand for carbon nanotubes will rise rapidly.
Henan KELAIWEI nano carbon material company is a high-tech company founded by the technical team led by Professor Sun Xiaogang of Nanchang University and Zhengzhou Dengcao group. Henan KELAIWEI Nano Carbon Material Co., Ltd. has an initial investment of 0.55 billion yuan, after the establishment, KELAIWEI will own the 300-ton whisker carbon nanotube powder project built by Henan company and Jiangxi company, which will be completed in two phases and will supply high-end products, silicon carbide long crystal technology, for China's carbon material industry.
Henan KELAIWEI Nano Carbon Material Co., Ltd. is committed to the manufacture and application of high-end materials of whisker carbon nanotubes. Thin film solar cells made of carbon nanotube nanomaterials have excellent performance and low price, and can be widely used in lower-price ceramic materials, metal sheets, graphite materials, etc. are used as substrates to make "solar cell Transparent Conductive Materials". The technology center of Henan KELAIWEI Nano Carbon Material Co., Ltd will devote itself to the in-depth research on the application materials of green and environmentally friendly energy.
What is graphite carbon fiber? The carbon fiber obtained after graphitization processing of carbon fiber at ultra-high temperature is graphite carbon fiber. The graphitization temperature is as high as over 2000 degrees Celsius, generally within 3000 degrees Celsius. Graphite carbon fiber and nano carbon fiber materials are different in addition, the higher the temperature of graphitization environment is, the larger the graphite microcrystals contained in the fiber will be. Silicon Carbide long crystal technology.
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.
