Carbon nanotubes surrounded by paper can function as a supercapacitor or a battery (when
paired with lithium).
Could paper be the future of power in electronic gadgetry? Just as plastics unleashed a
revolution in the manufacture of everyday materials, a new power source composed of
cellulose, carbon nanotubes and a dash of liquid salts could revolutionize the energy behind
gadgets from iPhones to pacemakers.
"We have a paper battery, supercapacitor and battery-supercapacitor hybrid device that could
be used in a variety of energy storage applications," says biological and chemical engineer
Robert Linhardt of Rensselaer Polytechnic Institute (R.P.I.) in Troy, N.Y., who helped lead the
team that made the discovery. "These devices are lightweight and flexible and are primarily
composed of cellulose paper—an environmentally friendly and biocompatible material."
