According to overseas media reports, Researchers in ArgonnenationalLaboratory, the US AgonnenternationalLaboratory, announced that new breakthroughs in the technical field of lithium oxide battery, and scientists in the United States and South Korea showed the development of lithium oxide (LiO2). Lithium - air battery. According to the report of "Natural" magazine, the introduction of lithium-air battery will create a primary river based on high-energy density batteries developed based on lithium oxide, and also supplies possible to other uses of compounds such as oxygenation materials.

During the chemical reaction, the lithium-air battery can form a lithium alkoxide (Li2O2), and the lithium oxide is a solid precipitate for blocking the electrode pore and reducing battery performance, is also an indispensable part of the charge and discharge reaction process. Previously, the industry had pointed out that lithium-air battery technology still needs to overcome many problems. If you want to invest at least 10 years.

However, a large number of findings show that the superoxide and the lithium hydroxide formed by lithium-air batteries can be used as an important part of the discharge product. Unlike the lithium peroxide, superoxide can easily decompose into lithium ions and oxygen ions, thereby improving productivity and extensioning battery cycle life. In addition, theoretical calculation results show that some forms of superoxide life is longer.

In the test, the atoms contained in the electrodes used by the researcher are separated, so that the amount of lithium oxide remains up to rise. Agong National Lab scientist Larrycurtiss and KhaliLamine explained that the battery developed based on lithium oxide can be in theoretically made a lithium-air battery composed of a closed system. Open systems often need to be ingestion of oxygen from the external environment, while the closed system is not, the latter can also make the battery more secure and more efficient.

At the end of last year, Claregrey, a professor of the University of Cambridge, and her team had also overcome the difficulties in the process of lithium-air battery technology. The team summarizes that theoretically, lithium-air battery energy density can reach 10 times the current marketable lithium-ion battery, the battery work efficiency is as high as 90%, and the number of charging is 2,000 times.
