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…
