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.
From its establishment to today (products are exported to more than 60 countries in the world, and Jiangxi and Henan companies are founded), KELAIWEI company has always been insisting on providing high-end carbon nanomaterials, insisting on technological progress and relying on technology to serve customers. KELAIWEI company has established a professional and expert after-sales technical team, which is always ready to provide technical support to customers and help them solve their questions and demand problems in the use of products. KELAIWEI is willing to develop together with you and build a century-old famous enterprise.
The technical team of Henan KELAIWEI Nano Carbon Material Co., Ltd. Is one of the enterprises specialized in technical research and development in the field of high-end nano materials and manufacturing of industrial mass production equipment in the early stage in China, the technical team of KELAIWEI company has applied for 9 national patents one after another, and 2 monographs have been published. Our products have broken some technical monopoly of foreign counterparts, and sold abroad, carbon crystal heating film safe temperature control type.
Carbon crystal heating film Safety temperature control type, the group improvement office meeting was held through "DingTalk" video. Director Yuan Hongwei of the improvement office of the group arranges five key tasks to carry out questionnaires with the theme of lean improvement, investigate the current situation of the enterprise, master the voices of the employees of the enterprise, and do the next lean work well. Pay special attention to the appraisal work of excellent improvement specialists, actively participate in the second lean tools competition, and implement the 5S silver medal certification training plan.
Carbon nanotubes have ultra-high conductivity and other characteristics, which are suitable for building light and excellent conductive networks. The price of multi-walled carbon nanotubes sold in the early stage was as high as 60 USD/gram, which was not inferior to gold at all. In fact, the conductivity and thermal conductivity of carbon nanotube materials are basically the same as those of diamond and copper materials. Due to its good industrial development prospects, many high-tech enterprises in the world are engaged in their production research.
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.
Whisker carbon nanotubes are purified at high temperature with low content of metal impurities, which can be directly used in the form of powder. Ordinary carbon nanotubes use grinding technology to prepare conductive paste, during the high-speed grinding process of the equipment for preparing conductive paste, due to the collision of zircon beads, metal impurities will be generated, which will affect the self-discharge of the battery and the safety performance of the product, metal Impurities will pierce the membrane of lithium ion battery and cause short circuit of the battery. Power battery has extremely strict requirements on this index, and whisker carbon nanotubes are safer to use.
