Washington, December 09: Dip a piece of paper into ink infused with carbon nanotubes and silver nanowires, it morphs into a real battery. Crumple the piece of paper and it still works.
These are some of the newest ways of storing power, says researcher of material science and engineering.
Stanford scientists are harnessing nanotechnology to quickly produce ultra-lightweight, bendable batteries and super capacitors in the form of everyday paper.
The paper batteries are treated with a nanotube ink, baked and folded into electrical generating sources.
Simply coating a sheet of paper with ink made of carbon nanotubes and silver nanowires makes a highly conductive storage device, said Yi Cui.
Like batteries, capacitors hold an electric charge, but for a shorter period of time. However, capacitors can store and discharge electricity much more rapidly than a battery.
