New battery tech lasts for days, charges in seconds

Scientists from the University of Central Florida (UCF) have created a supercapacitor battery prototype that works like new even after being recharged 30,000 times. The research could yield high-capacity, ultra-fast-charging batteries that last over 20 times longer than a conventional lithium-ion cell. "You could charge your mobile phone in a few seconds and you wouldn't need to charge it again for over a week," says UCF postdoctoral associate Nitin Choudhary.
