Supercapacitors Take Huge Leap in Performance

The Economist has published an article this week highlighting the work of Lu Wu at the Gwangju Institute of Science and Technology in South Korea in which he and his colleagues have developed a process for producing graphene that could lead to better supercapacitors.

While The Economist article makes some pretty incredible claims, such as that the graphene-based supercapacitors produced by the Korean researchers can store more energy per kilogram than lithium-ion (Li-ion) batteries, the actual research paper in the Journal of Power Sciences offers a less-hyped but nonetheless impressive list of achievements from the research.  Read more...
