Tesla's Musk says capacitors "will supercede" batteries

While speaking at the Cleantech Forum in San Francisco, CA last week, Elon Musk, chief executive officer of Tesla, said he's willing to bet against batteries to be the technology that finally delivers the breakthrough that electric-drive vehicles need to become mainstream. Earth2Tech quotes Musk saying:

Digital quantum batteries hold a lot of promise, theoretically

Want a battery that recharges insanely fast and can hold more than ten times the energy of a lithium-ion battery? Then get in line for one of the digital quantum batteries that are being developed discussed at the University of Illinois at Urbana-Champaign. And don't forget to pack a lunch, because these packs won't be ready for a while. Perhaps in time for the 2030 Tesla Model Z.

Most promising green technologies number four: ultracapacitors

While batteries make most of the headlines when it comes to the energy storage requirements of electric cars, the capacitor could be an exciting and viable alternative. Unlike batteries, which store chemical energy and make it available for use as electrical energy, capacitors store energy in the electric field between a pair of conductors. Supercapacitors, or ultracapacitors, are currently being developed which could rival batteries in the amount of energy that they can store. Whether capacitor

Ultracapacitors will be the next hot thing for hybrids

In a recent article in Popular Mechanics, editor Mike Allen declared himself a fan of ultracapacitors for hybrid cars. He explains how he visited Honda's development facilities 15 years ago and found himself testing a mild hybrid that used an ultracapacitor to store energy. However, we all know that current hybrids don't use ultracapacitors. Instead, they have powerful batteries, which have a higher power density and a price that is going down.
