"By dipping an ordinary piece of paper into ink infused with carbon nanotubes and silver nanowires, scientists have been able to create a low-cost battery or supercapacitor that is ultra-lightweight, bendable and very durable. The paper can be crumpled, folded or even soaked in acidic or basic solutions and still will work.

Stanford University scientist Yi Cui had previously created nanomaterial energy storage devices using plastics, but his new research showed that a paper battery is more durable because the ink adheres more strongly to paper. Coating a sheet of paper with ink made of carbon nanotubes and silver nanowires produced a highly conductive storage device that could be used in a multitude of applications.
