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 energy to travel the same distance. The technology for a high-capacity lithium-ion battery that charges quickly and operates efficiently is still an unrealized goal—but researchers are now closer than ever.
