New Supercapacitor Tech May Help Charge Your Smartphone in Seconds: Study
HIGHLIGHTS It can majorly improve energy-storage devices called supercapacitors The design doubles the amount of electrical energy the device can hold Supercapacitors are a promising, green alternative to regular batteries You may soon be able to charge your smartphone within seconds, thanks to a novel technology developed by researchers that can significantly improve energy-storage devices known as supercapacitors. The design doubles the amount of electrical energy the rapid-charging devices can hold, paving the way for eventual use in everything from smartphones and laptops, to electric vehicles and high-powered lasers, researchers said. "We are showing record numbers for the energy-storage capacity of supercapacitors," said Michael Pope, professor at the University of Waterloo in Canada. "And the more energy-dense we can make them, the more batteries we can start displacing," said Pope, who led the research published in the journal ACS Nano. Supercapacitors are a...
