MIT developing carbon nanotube ultracapacitors to replace batteries

[Guest]

Batteries provide power for most of our daily gadgets, but they are bulky and must be replaced often. Now, researchers at the Massachusetts Institute of Technology Laboratory for Electromagnetic and Electronic Systems (LEES) are studying a new breed of "supercapacitors", which use carbon nanotubes (CNTs). Professors Joel Schindall and John Kassakian, along with Ph.D. candidate Riccardo Signorelli believe the unique properties of the CNTs could help make supercapacitors that could one day let us charge our laptops instantly.
