Scientists at University of Central Florida (UCF) have developed a supercapacitor battery prototype that lasts 20 times longer than a conventional lithium-ion cell. It charges in seconds.
“If they were to replace the batteries with these supercapacitors, you could charge your mobile phone in a few seconds and you wouldn’t need to charge it again for over a week,” said Nitin Choudhary
Better still, the battery doesn’t degrade. After around 18 months, the typical lithium-ion battery cell starts a slow process of degradation where each charge cycle leads to fractionally smaller amounts of overall capacity.
The prototype doesn’t experience the same levels of degradation and still works like new after being recharged 30,000 times. Read more…
