MIT research may spell end for the battery. Supercapacitor could make electric car viable

June 26, 2006View for printing

Scientists at the Massachusetts Institute of Technology think they're on the verge of making traditional batteries obsolete.

The researchers are working on a new device that uses carbon nanotubes to store and release electrical energy in a system that could carry as much power as today's lead or lithium batteries.

But unlike the rechargeable batteries used on today's cellphones and laptop computers, these devices could be recharged hundreds of thousands of times before wearing out.

And instead of taking hours to recharge, they could be powered up in about the same time it takes to fill up a gas tank.
