Default Batteries of the future to charge in seconds?

According to a story over at ScienCentralNews researchers at MIT are working on a new type of battery which is more like a capacitor than todays 'chemical reaction' battery. Typically a capacitor has a far lower capacity (by size) than a battery but researchers are using tiny nanotube filaments to increase the surface area within the capacitor to increase storage. These new 'batteries' could in theory charge in just a few seconds yet be the same size and capacity as todays rechargeable batteries, they may also never need replacing as they wouldn't degrade in the way current batteries do.

buy one and then drive whole life? don't think so. i know that meni things are existing and could be free, but companyes will not do that as then they will stey off big profit.

Very cool indeed. Like the article mentions, if we could start seeing this technology in product form within 5 years, that just might change the entire way we view batteries.

The construction industry will make sure this happens. and as we get most of our battery tech through them, it will come to pass. But be rest assured the caps will fail, degrade or diminish in performance some how, some way, as we all know there is no silver bullet to fuel/energy sourcing.

My wife had a friend in college (she's an EE) who was trying to figure out how to build a 1 farad capacitor.

Quite right, & the automotive industry has also done some research into capacitors, from what I've read(meant for use in a hybrid system, in place of batteries), but not much progress has been made over the time since I first read about it(which was maybe 5 years ago or so). I specifically remember that Chrusler wanted to set up a kind of flywheel capacitor as part of a racing hybrid system for running in endurance racing(like the 24 Hours of Daytona or LeMans), but they had too much trouble getting the flywheel to hold up in a car. But as always, it's only a matter of time.....

I have seen a 1 Farad capacitor in a UK equivalent of Radio Shack, it was designed for high power car amplifiers etc.

It was also about 1 foot long!

The article says:
"...so even today's most powerful capacitors hold 25 times less energy than similarly sized standard chemical batteries."
Even at 25% less, a capacitor the same size as a 4300mah battery would still yield about 3200mah?
If this is true, even with caps being 25% less, they can still be used in RC as we were running 3000 mah not too long ago.
Or am I totally wrong?

The article says 25 TIMES, not 25 percent. 25 times less a 4300mah battery would be 172mah.

forget batteries, caps, lipo there ancient technology we have perpetual motion wahoo and these guys will be the richest people to walk the planet.
it can put out so much power and blows the circuits.

Btw if you short a 1 farad cap your ears will be ringing and watch your eyes they hold a massive amount of power I have seen

Many brands of big caps like audiobahn makes a 10 farad cap
