"Spicy world of NanoScience"
Researchers from Nanotek Instruments have developed a new graphene-based supercapacitor that can store as
much energy as NiMH batteries, but charge and discharge in minutes or
even seconds. The new device has a specific energy density of
85.6 Wh/kg at room temperature and 136 Wh/kg at 80 °C. These are the
highest ever values for "electric double layer" supercapacitors based on
