Anyone who's had to recharge an EV -- or, for that matter, any mobile device with a very big battery -- knows the pain of waiting for hours while a lithium-ion pack tops up. South Korea's Ulsan National Institute of Science and Technology has developed a conduction technique that could cut that charging time down to less than a minute. By dousing the nanoparticle materials of the battery in a graphite solution that's then carbonized, the researchers make a web of conductors that all start charging at once; current batteries have to charge towards the center slowly, like a not-very-edible Tootsie Pop. The immediate goal is to develop a secondary battery for an EV that could provide extra mileage in a matter of seconds. Here's hoping that the Ulsan team's fast-charging battery is more viable than others and spreads to just about everything -- we'd love to have EVs and laptops alike that power up in as much time as it takes to fill a traditional car at the pump.
