Korean carbon-coated lithium-ion battery could cut recharge times down to minutes

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 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.
