Decorating Graphene Oxide with Ionic Liquid Nanodroplets: An Approach Leading to Energy-Dense, High-Voltage Supercapacitors
The ability to charge cellphones in seconds is one step closer after researchers at the University of Waterloo used nanotechnology to significantly improve supercapacitors. Their novel design roughly doubles the amount of electrical energy the rapid-charging devices can hold, helping pave the way for eventual use in everything from smartphones and laptop computers, to electric vehicles and high-powered lasers.
“We’re showing record numbers for the energy-storage capacity of supercapacitors,” said Michael Pope, a professor of chemical engineering who led the Waterloo research. “And the more energy-dense we can make them, the more batteries we can start displacing...
