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.

An electric car equipped with these "batteries" could actually be recharged while still on the road and moving. If the standard set of batteries could go 20 or 50 or 100 miles/kilometers between charges, then the highways could have high power induction grids every 5 or 10 miles/kilometers. If you drive over the grid, you get charged to perhaps 90% capacity and then billed for the amount of power you used. Then just merge back into traffic. High power substations could keep the voltages high for quick charging. Existing gasoline stations just add induction grids to serve multiple fuel types.

Hmm something about being zapped with a 100kW arc... you think slot car contacts wear out fast? lol

Ah induction... well... hmm... having to limit power to safe levels would imply longer charge times.

induction grid in a freeway? not very feasible...too likely to ground itself after a period of years. and very expensive to build "new" into a road.
