Graphene Supercapacitor Breakthrough Offers Energy Density Comparable to NiMH Battery!
Photo: Wikipedia , CC But With all the Advantages of Supercapacitors As you can see above, graphene is a one-atom thick sheet of carbon atoms, very similar to carbon nanotubes , except for the “tube” part. This wonder-material has very interesting electrical properties that have allowed researchers to create a graphene-based supercapacitor that exhibits a “specific energy density of 85.6 Wh/kg at room temperature and 136 Wh/kg at 80 … Read the full story on TreeHugger
