Batteries that recharge in seconds

Researchers at the Massachusetts Institute of Technology have developed technology to produce batteries that can be recharged in seconds, rather than minutes or hours, and that will not wear out or suffer from any memory effect.

Batteries that recharge in seconds
The new technology has been developed from capacitors which store energy as an electric field between electrodes, rather than chemical reaction like in standard batteries. This allows them to store a charge much quicker than batteries can, but until now capacitors could not hold as much charge as batteries.

The researchers overcame this by covering the electrodes with millions of tiny hair-like structures called nanotubes which increase the surface area, and therefore increase the amount of charge that can be held.

The new technology could be applied to anything which currently uses a battery. Small appliances like digital cameras through to larger power hungry devices such as electric cars could all benefit from this advance.

If it's true great, but as it's US research I'll wait and see. I'm still waiting for them to reproduce cold fusion from their last inflated claim.
This probably works like a charm. But one battery would cost too much to make so that it would not be profitable.

Couldn't agree more David.

The battery manufacturers will strongly oppose this idea, like the petrol companies and the engine that ran for 30 years on water.

Oh, the responses really made me smile!
The use of carbon nanotubes in a vast array of different technologies is already well underway. There are some really interesting applications. there is a lot of Japanese research too, not to mention other countries, and quite a bit by the battery manufacturers themselves.
Really, seeing what developments there are in the manufacture of these molecules, they aren't going to go away. Having access to the largest database of scientific and technical information and intellectual property, I can assure you of that!

Krimage, my comment was on reliability of US research claims not on the existence of nanotubes. They are hardly news. Already used inside verious chips in manufacturing sector.
We would all welcome quicker recharge times but what i want is longer lasting batteries with a 30 to 40 minute recharge time the hydrogen battery isn't far away either so lets wait and see.
