Carbon Nanotubes are being applied to supercapacitors, and the result is showing promise in replacing older battery technology. Scientists at the University of Texas at Dallas have managed to create supercapacitor "paper", comprised of randomly tangled carbon nanotubes embedded in a polymer.
The supercapacitors store more energy per space than standard chemical systems, without the associated dangers found in chemical methods. The technology is said to be easy to scale for fabrication, so we might see this in real world products relatively soon.
