Batteries could soon be a part of the device itself, or even the box is came in, when these paper batteries based on nanotechnology hit the market. Look for paper batteries wrapping up your electronic devices within three years. R.C.J.
A paper battery based on carbon nanotubes and silver nanowires could store an electric charge in a mobile device. Researchers also claim the new battery is disposable and that its shape could conform to the shape of different devices. A Stanford University researcher said his team has demonstrated conductive coatings for battery components ranging from supercapacitors to inexpensive electrodes. The process could be commercially available in several years, according to Yi Cui, a Stanford assistant professor of materials science and engineering.
