When will there be a revolutionary breakthrough in battery technology? It is believed that this is a topic that many people are very concerned about, but there are often new battery technologies exposed, but there are basically no commercially available ones.
Chinese scientists have developed a lithium battery that can be used in the extreme cold conditions of minus 70 degrees Celsius, even in outer space, according to the Xinhua news agency.
It is reported that this scientific research result came from the team led by Xiayongyao of Fudan University in China. He used ethyl acetate, which has a low solidification point and can conduct electricity at extremely low temperatures, as an electrolyte, and used two organic compounds as electrodes, namely PTPAN cathode and PNTCDA anode.
The organic compounds do not need to embed lithium ions into the molecular matrix of the electrode to avoid the slow embedding process of conventional lithium batteries at low temperatures.
Lithium batteries will lose 50 % of their performance at minus 20 degrees, and 88 % at minus 40 degrees, which is why mobile phones will slow down or accidentally shut down in winter or cold areas.
The new battery uses a lot of materials, is not expensive, and is environmentally friendly, but researchers also admit that to commercialize it, the main problem is that the energy density of the new battery is too low to match the current lithium battery.
