Report: Nanotechnology creates paperlike battery

'A battery built with molecule-sized tubes of carbon can be made as thin and flexible as a sheet of paper, researchers from Rensselaer Polytechnic Institute say.

The new technology, described in a report published Monday in the Proceedings of the National Academy of Sciences, is 90 percent cellulose, the material used in paper, imprinted with carbon nanotubes and impregnated with conductive liquid salt.

The battery works like any other, while it can be twisted and rolled without impairing its function, the researchers said. That may make it useful in medical devices such as pacemakers, digital displays, electric cars and smart cards, they said.

"It's essentially a regular piece of paper, but it's made in a very intelligent way," researcher Robert Linhardt, a Rensselaer engineering professor, said in a statement. "The components are molecularly attached to each other."

The tiny carbon nanotubes store power, while the cellulose provides insulation and the salt acts as an electrolyte, researchers said.

"The end result is a device that looks, feels and weighs the same as paper," Linhardt said.'
