According to foreign media reports, Professor Atsuoyamada at Tokyo, Japan and its team recently developed a material, which can significantly extend battery life and make the battery have higher capacity. From smartphone to pacemakers to cars, batteries supply power to many products in the world, and their importance will become bigger and bigger. Many people think that the battery should be improved in two aspects, namely battery life, capacity (how much power can store, to meet future needs.
At present, most electronic devices use lithium-ion batteries, and another battery based on sodium is not lithium, which may also be very popular. These two batteries can store and release a large amount of charge due to its unique transmission of electrons due to their constituent materials. However, over time, the lithium ion battery and sodium cell are repeated charge and use cycles, the storage capacity will be significantly reduced.
There are several metal materials in ordinary batteries. When the battery charges, such metal layers degrade and crack or flakes, resulting in stackingfault, thereby reducing battery storage and transmitting charges. When such materials are called the weak combination of Vanderwaalsforce, the stacking is wrong.
Yamada and colleagues prove that if the battery is made of a material called redox laminated oxide (Na2RuO3), the degradation application of the battery charge and discharge cycle will be reduced, and the metal layer will be self-repair. Moreover, the researchers have proven that the material will be tightly grasped by Coulombicattraction, which is much more powerful than Van Devarers. YAMADA said: "This means that the battery will not only have longer service life, but also damage the level will be reduced.
New battery energy density is critical to realizing electrification traffic. ".
