Flexible paper batteries could meet the energy demands of the next generation of gadgets, says a team of researchers. They have produced a sample slightly larger than a postage stamp that can release about 2.3 volts, enough to illuminate a small light. But the ambition is to produce reams of paper that could one day power a car. Professor Robert Linhardt, of the Rensselaer Polytechnic Institute, said the paper battery was a glimpse into the future of power storage.
