The new batteries can also be recharged hundreds of thousands of times say MIT researchers

You could be charging your long lasting batteries in a matter of seconds in the future if several researchers at MIT get their way. According to a report on ScienCentralNews, researchers at MIT have discovered a new way of making batteries that involves using millions of nanotubes. Leaping over traditional battery technologies, the new types of batteries are based on capacitors, which have been around even longer than the battery itself.

A capacitor maintains a charge by relying on two metallic electrodes. The actual storage capacity of a capacitor is directly proportional to the surface area of those electrodes, and unfortunately making a capacitor in traditional battery sizes means that the electrode surface area is simply too small. To overcome this, the researchers cover the electrodes with millions of nanotube filaments, effectively increasing the surface area.

According to research team leader Joel Schindall "[the nanotube battery] could be recharged many, many times perhaps hundreds of thousands of times, and ... it could be recharged very quickly, just in a matter of seconds rather than a matter of hours." With such promise, Schindall and his team believes that the new technology will revolutionize portable electronics as well as the automotive industry. "Larger devices such as automobiles where you could regeneratively re-use the energy of motion and therefore improve the energy efficiency and fuel economy."

The research team at MIT is hoping that this new promising technology will show up in the market in less than five years from now.

exactly nice you can chatge the baterry in seconds but how much watts they produce and how long they last, imagine charging your laptop in 10 sec

it doesn't matter, the key here is size, you could stack as many as of these as you need. If this is true and there's no hidden catch then it could be the biggest breakthrough since semiconductors ... the number of applications is huge and probably one of the most appealing is electric rechargable cars ...

ACtually that trend is reversing these last years... the oil companies are made of intelligent ppl who understand that money and power comes from controlling the energy sources. Since oil will soon belong to the past they are largely investing in other forms of energy.

Tesla Motors is designing electric cars:

Hopefully this battery technology will be able to expand the range and durability of their vehicles tremendously. Having a car with batteries that will last 3000 to 5000 years and goes thousands of miles on a single charge is much more appealing than having a car with batteries that will last 3 to 5 years and will go 250 miles on a single charge.

Or better yet...

...recharging your laptop via USB cable via another pc. This is the future folks.
