Chinese scientists have developed a lithium battery capable of operating at minus 70 degrees Celsius, which could one day be used in extremely cold regions on earth and even in outer spaceThe new battery, developed by xia yongyao's team at fudan university in China, USES ethyl acetate, which has a low freezing point and conducts electricity at extremely low temperatures, as an electrolyte, and two organic compounds, PTPAn cathode and PNTCDA anode, as electrodes, according to research published in the latest edition of joule, an American journal of energy science.
