Today’s batteries do not work well in cold or hot temperatures. Either they won’t start, they won’t take you far, or they shut off. Even just a slight drop in temperature can cause the battery to lose 30%-50% of its energy.
Future solid-state batteries aren’t much better because ions will have a harder time traveling through the solid electrolyte. Unless you live in a place where it is 50-70 degrees year-round, you need a battery that can operate – dependably – in wide temp ranges. Prieto’s battery provides the solution.
