CNT Battery Technology
By | June 10, 2009
Carbon Nano Tube Battery the breakthrough technology is holding forth the promise of charging electronic gadgets in minutes, never having to replace a battery again, and dropping the cost of hybrid cars. Indeed, the technology has the potential to provide an energy storage device ten times more powerful than even the latest batteries in hybrid cars — while outliving the vehicle itself.
This new technology carbon nanotube, will greatly increasing the surface area of electrodes and the ability to store energy.
Now the new CNT battery will allowing the devices to retain the power and longevity advantages, while storing about as much energy as the batteries used in hybrids.
The amount of energy CNT battery can hold is related to the surface area and conductivity of their electrodes. Using carbon nanotubes increased the surface area by about 50,000 square centimeters, compared with 2,000 square centimeters using the carbon in a commercial ultracapacitor today. The highly pure carbon nanotubes are also extremely conductive, which will increase power output over existing ultracapacitors, the researchers say.
The CNT technology will find applications beyond hybrids, too. CNT batteries will allow laptops and cell phones to be charged in a minute. And unlike laptop batteries, which start losing their ability to hold a charge after a year or two, they could still be going strong long after the device is obsolete. “Theoretically, there’s no process that would cause the CNT battery to need to be replaced.
