Nanotech coming to laptop batteries?
Ars Technica has an interesting
article about a new battery-enhancing technology being developed at the Massachusetts Institute of Technology. MIT researchers have reportedly been using carbon nanotubes to increase the internal surface area of ultracapacitors, which are capacitors with enhanced energy storage. Augmenting surface area with carbon nanotubes further increases energy storage, potentially allowing for power densities up to three hundred times higher than those of conventional Lithium-Ion batteries. The technology is still at the experimental stage, though; commercial applications aren't expected for another three to five years.
