‘Alaska will kill you’: At 40 below zero, everything breaks — including the soldiers
“The physics behind it is you have these different materials in the battery: anode, cathode, electrolyte. One of the key problems is the electrolyte, which is liquid-based,” said Ms. Lee, adding that those traditional batteries simply freeze eventually. “Our material, a liquefied gas electrolyte, is a new material for batteries that simply doesn’t freeze until well below temperatures that you would see here on Earth.”
