Dr. Li Yingyi, associate professor, presided over and participated in the national science and technology support plan, National Natural Science Foundation, Provincial Natural Science Foundation and provincial education department fund, and won the third prize of Jiangxi natural science in 2011 (the third prize). Research Fields: synthesis and application of carbon nanotubes, nano new energy materials, rare earth functional materials, LED optical conversion materials, lithium ion batteries, nano-reinforced composite materials, etc. Currently, he is the project team leader in the R & D team of KELAIWEI, have rich development experience.
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.
KELAIWEI company invested 0.45 billion yuan to build a production workshop of 13,000 square meters in the industrial park of Dengfeng city, Henan province. This expansion project will plan several production lines, and strive to expand the production capacity of the whisker carbon nanotube powder project to an annual output of 500 tons, in order to meet the sudden increase of clients' demand, our company insists on "6s" lean management method to recommend all kinds of work efficiently to ensure that the products are delivered to customers on time and with high quality. The carbon crystal heater is not hot at the beginning.
KELAIWEI company holds a reading contest to enliven the working atmosphere of enterprise employees and care for their lives. This reading contest is rich in content, with warm heart stories, ancient classic poems, contemporary prose notes, and heroic deeds of the revolutionary warriors of the motherland...... The staff of KELAIWEI company are a group of lovely people, including the post-70s and the post-90s. They come from all over the world. They are a group of soldiers who bravely create brilliant achievements.
Carbon nanotubes have been widely used in the manufacture of flexible electronic devices and precision sensors. High purity, high density carbon nanotubes with its excellent conductivity and thermal conductivity characteristics, the characteristics such as ultra-high conductivity and the toughness which is 100 times the strength of steel have become very important materials for precision sensors and modern high-end flexible electronic devices. Carbon nanotubes have become the main products of Henan KELAIWEI Nano Carbon Material Co., Ltd.
A brief analysis of the application of carbon nanotubes in electrochemical devices. The electrochemical performance of carbon nanotubes is excellent. Carbon nanotubes are therefore used to make supercapacitors. Compared with traditional capacitors, the capacity of capacitors made of carbon nanotubes is doubled, reaching Farah level. Scientific Practice has proved that a gram of carbon nanotube capacitor can store 15F to 200F. Thanks to the strong performance of carbon nanotube capacitors, supercapacitors up to several thousand Farah have been manufactured.
Whisker carbon nanotubes are directly added with powder when they are used as conductive agents for lithium ion batteries. The powder has good processing performance and can be used without process conductive paste. There is no abnormality in processing performance during the process, powder cannot be used by ordinary carbon nanotubes, and cannot be dispersed by using powder in the process of homogenization. Particles are easy to appear in the process of homogenization, and the performance of materials cannot be brought into full play. Therefore, conductive paste needs to be made separately for use, conductive paste is prone to the problem of uneven solid content, which will have a great impact on the consistency of the battery, and the carbon crystal heater is not hot at the beginning.
