KELAIWEI is backed by Henan denggou group. The predecessor of Zhengzhou Dengcao Group Co., Ltd. is the Dengcao coal mine established in 1973. After years of development, Dengcao group has gradually covered many fields such as coal, finance, education, real estate and so on, and has accumulated a lot of shopping experience. With the strong support of the group company, KELAIWEI actively promotes technology and product innovation, increases investment and strives to move towards high-tech enterprises.
In 2020, KELAIWEI had been deeply engaged in the research and development and preparation of nanomaterials for 20 years. Our company fully owns independent intellectual property rights of relevant industries and has applied for 106 patents (including 9 national authorized invention patents and 2 international PCT patents). Our deep cooperation customers have spread all over the world (more than 60 countries such as Asia, America, Europe and Africa). All the staff of KELAIWEI are forging ahead and looking forward to establishing a deep partnership with you.
Carbon atoms increase the melting point of crystals. KELAIWEI company relies on the research and development achievements of the expert research and development team of Professor Sun Xiaogang of Nanchang University in China for more than 20 years to carry out the industrial and mass production application of high-end nanomaterials. After years of unremitting efforts and continuous investment, our company has achieved the production capacity of far infrared heating paper reaching 30 tons per year, and the production capacity of designed whisker carbon nanotube powder production line reaching 300 tons per year, around 2008, 0.45 billion yuan has been spent on production capacity expansion.
In 2020, the safety production season training work of Henan KELAIWEI Nano Carbon Material Co., Ltd was held as scheduled. Realizing safe production is the responsibility and obligation of enterprises. Our company attaches great importance to the safety production guarantee work. Give priority to safety work in daily work and on duty on holidays. In normal times, employees are strictly required to carry out production in accordance with the safety production operation specifications, and safety training is held regularly every quarter every month.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has been engaged in the research of carbon nanotube materials for more than 20 years. Carbon nano-tube materials used in anode conductive additives of lithium batteries will improve the efficiency by 10% compared with carbon black, and can save a lot of conductive materials, increase the capacity of lithium batteries, and delay the service life of high-end lithium batteries at the same time. Therefore, it can be said that the performance of carbon nanotube materials is quite excellent.
Carbon atoms increase the melting point of crystals, and the heating principle of graphene electrothermal film is briefly introduced. First of all, graphene electrothermal film is a new material for processing and synthesis, which mainly passes through metal-carrying strips (common copper metal) between two layers of insulating polyester film. And graphene conductive ink with excellent conductivity is produced after hot pressing. Different from carbon fiber cables using irregular motion friction between atoms to make heating, graphene electric heating film generates heat by continuously releasing heat energy after carbon molecules that produce Brownian motion collide with each other.
Acetylene black is a particle conductive agent, which needs more additive amount when forming the conductive network. The larger the additive amount is, the lower the proportion of active material will be, and the energy density of the battery will be reduced. The whisker carbon nanotubes have nanofibers with linear structure, the network conductive structure can be rapidly formed in the electrode with extremely low additive amount and has excellent conductive efficiency. Better performance can be maintained when the battery is multiplied or circulated.
