Efficient and inexpensive sodium batteries are available

    According to a report by THE WEBSITE of Russia Today on July 15, scientists in Russia and Germany have developed a new process for making sodium batteries.The sodium battery can replace the current use of lithium batteries, has many advantages: a significant reduction in the manufacturing cost, lithium - kind of rare metals, high prices, shortage of resources, sodium is a kind of common metal, double, of an inexhaustible, its richness, unparalleled, sodium ion batteries cost is only about 1/100 of the lithium ion battery, lithium battery in the supplementary material for copper at the same time, and sodium battery auxiliary available aluminum, so the cost of the battery can fall further;The sodium battery has a three-layer structure, consisting of two layers of graphene and one layer of sodium ions. Its capacity is about 335 mA/g, which is similar to that of the traditional graphite anode lithium ion battery.Third, the three-layer structure battery has good stability, and the stability increases with the increase of the number of layers.

    Currently, the sodium-graphene multi-layer structure battery is still in the test stage, and once successfully entered into commercial production, it will be a milestone in the battery history, which will lead to a new generation of batteries with larger capacity and lower cost.The team of scientists came from The Russian State Technical University, the Institute of Biochemical Physics of the Russian Academy of Sciences, the HZDR Research Centre in Germany and the Max Planck Institute in Germany.
