In an innovation that resists frost, Russian scientists have discovered a way to make lithium-ion batteries, which are commonly used in various electric devices and cars, withstand extreme cold.
In addition, scientists at the Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences, in cooperation with the Moscow Institute of Electronic Technology and Moscow University, were able to create battery cells based on nanofibers of the element germanium. Thanks to the use of these fibers, the capacity of the battery increases and it works effectively even at temperatures of minus 50 degrees Celsius.
The electric charge, thanks to which these batteries produce energy, is transmitted between two plates (two electrodes), one of which in lithium-ion batteries is made of graphite (anode) and the second of compounds of lithium and cobalt, or lithium and iron (electrode). According to what was reported by “Russia Today”, according to the Russian newspaper “Izvestia”.
And the efficiency of the electrodes (electrodes) decreases in cold weather according to the laws of physics. Scientists have come to the conclusion that the use of germanium nanofibers in the (anode) instead of graphite helps to maintain the energy level even at low temperatures.
