Liquified gas electrolytes power new lower-temperature battery

Liquified gas electrolytes power new lower-temperature battery

Science
June 16 (UPI) -- Scientists at the University of California, San Diego have developed new electrolytes capable of powering batteries at temperatures as low as negative 80 degrees Celsius.The technology could help make lithium ion batteries safer and more efficient, as well as boost the range of electric vehicles during cold winter months. The new batteries could also power vehicles and instruments operating in extreme cold, like space rovers, satellites and high-alitiude weather baloons.The electrolytes are composed of liquefied gas solvents. Many gases require extreme pressure to liquify. Gases that liquify at moderate pressures are less apt to freeze.To create their battery's electrolyte, researchers liquified fluoromethane gas. For the capacitor electrolyte, scientists liquified difluor...
