South Korean engineers find graphene electrodes can recharge in 16 seconds


graphene-supercap(01/Dic/2013) Yes, one day, you too may be able to fully recharge your plug-in vehicle’s battery in the amount of time it takes to decelerate down one of those runaway truck ramps. Assuming your brakes actually work, of course.

Engineers at South Korea’s Gwangju Institute of Science and Technology are researching the concept of graphene supercapacitors and how they can be applied to plug-in vehicle technology, Technology Review says. A simplified explanation is that the engineers have created an extremely porous version of graphene, turned it into a powder (which makes its surface area larger) and packed the powder into a cell.
