“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,” Steve Dent reports for Engadget. “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.”

“Supercapacitors can be charged quickly because they store electricity statically on the surface of a material, rather than using chemical reactions like batteries. That requires ‘two-dimensional’ material sheets with large surface areas that can hold lots of electrons,” Dent reports. “However, much of the research, including that by EV-maker Henrik Fisker and UCLA, uses graphene as the two-dimensional material.”

MacDailyNews Take: Like every “new” battery article, this one also ends, “The research is in early days and not ready for commercialization, but it looks promising.”

Wah-wah.
