Engineered electrode material moves battery research closer to 'holy grail'

An electric vehicle with such a battery could travel 600 miles on a single charge

12-Oct-2020 - Electric vehicles are gaining in popularity, but their long charging time is a significant detraction for potential customers. While a typical SUV with a combustion engine could travel 300 miles with a five-minute refuel, a state-of-the-art electric vehicle takes about one hour to store enough ...
