Gas electrolyte keeps very cold batteries running

The liquefied gas electrolyte allows lithium batteries to function at temperatures well below freezing

Of the various concerns that people have regarding electric cars, one of the most often-heard is the worry that their batteries won't work in cold winter weather. That may not be an issue in the semi-near future, however – scientists at the University of California, San Diego have created a new type of electrolyte that allows lithium batteries to work with "excellent performance" at temperatures as low as -60 ºC (-76 ºF). By contrast, traditional lithium-ion batteries tend to conk out at around -20 ºC (-4 ºF).
