According to foreign media reports, engineers at the University of Tokyo in Japan are constantly exploring new ways to improve existing battery technology. Recently, Professor Atsuo Yamada and his team have developed a material that can significantly extend battery life, and Let the battery have a higher capacity. From smartphones to pacemakers to cars, batteries power most objects in the world, and their importance will grow. Many people believe that the battery needs to be improved in two aspects, namely the battery life and capacity (how much power can be stored) to meet future needs. Most electronic devices use lithium-ion batteries, but another battery based on sodium instead of lithium may soon become popular. The two batteries can store and release a large amount of charge because of the unique way their constituent materials transfer electrons. However, as time goes by, the storage capacity of lithium batteries and sodium batteries will be significantly reduced during repeated charge and discharge and use cycles. There are several layers of metal materials in an ordinary battery. When the battery is charged and discharged, such metal layers will degrade and produce cracks or flakes, resulting in stacking faults, thereby reducing the battery's ability to store and transfer charge . When such materials are combined with a weak force called Van der Waals force, stacking faults occur. Yamada and colleagues proved that if the battery is made of a material called redox layered oxide (Na2RuO3), the degradation of the battery's charge and discharge cycle will be weakened, and the metal layer will repair itself, and the researchers prove The material will be gripped tightly by coulombic attraction, which is much stronger than van der Waals force. Yamada said: "This means that the battery will not only have a longer life, but also the level of damage will be reduced. Increasing battery energy density is essential for achieving electrified transportation." Screw machining and screw machine products with metal materials are all acceptable finished. The primary hardware materials of screw machined parts can be finished including copper, iron, aluminum and stainless steel. As a screw machined parts manufacturer, we specialize in processing long screw with hexagon sockets, precise and slender axle accessories. The best quality and high precision screw machining parts can be provided you the most competition price.
