According to the website of the Ministry of Science and Technology, the Korea Academy of Science and Technology released a news report that the university, together with Seoul University, used lithium-manganese-nickel-cobalt-manganese-oxide (LMR) materials to create a new type of anode material that could overcome the surface heating phenomenon. This technology can improve the performance of electric vehicle batteries. The research results were published in the international academic magazine Nano Letters. LMR materials have higher energy density and safety than other anode materials, but the crystal structure will appear unstable when charging and discharging. This phenomenon mainly occurs on the surface of anode material particles, and it has limitations in commercial applications. The Korean technology keeps the surface of the LMR anode material stable, which in turn forms a surface structure that rapidly conveys lithium ions, suppresses the phenomenon of material heating, and is simple and easy to fabricate. The results show that the new material maintains its original characteristics when it is subjected to high-speed charge and discharge over 300 times in 2 minutes. This technology can shorten the charging time and increase the distance traveled. At the same time, the anode material synthesis method and improvement scheme can be applied to the next generation of electric vehicles and medium and large-scale energy storage systems. Aluminum machining is the use of CNC machining out, including: drilling, boring, cutting, turning, screw. Product material are: aluminum6061,6061-T6,6063,6083,7075.5052,2017 .In the high-speed machining out of the workpiece has a good finish. Aluminum machining product surface treatment has anode, electroplating, sand blasting, laser engraving LOGO, mechanical drawing, rolling flower, according to the requirements of the drawings on the product anode all kinds of colors such as color, black, red, blue, yellow. We have a special inspection department to carry out inspection, to ensure that each size of products meet the requirements of the drawings, machining aluminum(cnc aluminum) is the most common in mechanical processing, low density, not easy deformation, high precision products. So it is widely used in various industries. Machining Aluminum,Fluorocarbon Machining Aluminium,Alumiunum Machining,Milling Aluminum Hong Kong RYH CO., LTD , https://www.cncmachiningpart.com
