“Stanford scientists are using nanotechnology to quickly produce lightweight and bendable charge-storage devices in the form of everyday paper. Simply coating a sheet of paper with ink made of single-walled carbon nanotube (CNT) and silver nanowire films makes a highly conductive storage device, said Yi Cui, assistant professor of materials science and engineering at Stanford University. The paper storage-device can last through 40,000 charge-discharge cycles - at least an order of magnitude more than lithium batteries.” Read more and watch the video at
