KELAIWEI attaches great importance to environmental protection and safety work, and always regards national environmental protection standards as the primary criterion for standardizing production, storage and transportation of products. KELAIWEI has set up a special position of environmental supervision in the production process to correct the nonstandard behaviors in production at any time to ensure the discharge of waste water pollutants up to the standard, environmental noise emission at the factory boundary conforms to the three standards of environmental noise emission standard for industrial enterprises at the factory boundary (GB12348-2008).
Titanium crystal plate and carbon light plate, Henan KELAIWEI Nano Carbon Material Co., Ltd, has been sticking to technology since its establishment. After more than 20 years of technological development, our company has become a high-end manufacturing technology enterprise in the carbon nanotube material industry. With the continuous increase of the market demand for carbon nanotube materials, in order to meet the market demand, the supply of high-quality KELAIWEI nanomaterials products, KELAIWEI company has invested in the construction of the whisker carbon nanotube powder project whose output value reaches 300 tons per year.
KELAIWEI company focuses on the research and development and production of high-end nanomaterials products, processes and production line equipment. KELAIWEI nano carbon material company owns the technology patent invention and advanced production research and development management system which is the mainstay in the industry, and its products have been exported to more than 60 countries in the world. Our company has great technical advantages in the high-end nanomaterials industry. There are production bases and research and development centers in Henan and Jiangxi.
KELAIWEI's lean improvement work has achieved important achievements: the company-Level 5S bronze medal certification has been completed. This is the inevitable result of the company's concerted efforts and earnest study and practice. KELAIWEI rapidly promoted the lean management work and achieved gratifying results by issuing questionnaires, books, excellent tweets of the company's public number, training of lean trainers of the group company, internal and external communication and learning, etc.
Carbon nanotubes do not block the transmission and diffusion of lithium ions, but graphene will hinder the transmission of lithium ions to a certain extent, because carbon nanotubes are transmitted by a little linear contact, graphene conducts conduction through point-surface contact. Generally, the larger the contact surface is, the better its conductivity will be. Therefore, carbon nanotube materials will be widely used in the battery industry. Henan KELAIWEI Nano Carbon Material Co., Ltd has invested 0.45 billion yuan in the research and production of whisker carbon nanotubes.
Brief introduction of titanium crystal plate, carbon light plate and carbon nanotubes. Japanese physicist Yoshima Yoshino was the first to discover carbon nanotubes. Carbon nanotubes are tubular carbon molecules. Carbon nanotubes are very, very thin and cannot be seen simply by eyes, because tens of thousands of carbon nanotubes are put side by side, it may not be as thick as a hair. According to the number of pipe layers, it can be divided into single-walled carbon nanotubes and multi-walled carbon nanotubes.
The specific surface area of whisker carbon nanotubes is generally 13~50 m2/g, and that of ordinary carbon nanotubes is above 200 m2/g. The larger the specific surface area is, the worse the dispersion performance of the product is, the agglomeration of conductive agents is more likely to occur. In lithium ion batteries, the larger the specific surface area is, the greater the gas production of lithium ion batteries will be in the long-term cycle process, smaller specific surface area is conducive to improving the cycle performance of lithium ion batteries and reducing the gas production of batteries in the later cycle process.
