ScienceNOW : Paper has been getting beat by electronics for years. But it may be about to stage a comeback. Researchers are reporting that they’ve made batteries and other energy-storage devices by printing layers of carbon nanotube–based ink atop standard photocopy paper. The result is a highly conductive sheet that can carry a charge and be easily incorporated into a flexible battery. Because of paper’s low cost, that could help lower the price of batteries used in electric vehicles, wind farms, and other renewable sources.
