‘Nano Paper’ That Can Conduct Electricity
Research team from Stanford University have transformed paper into an electricity storage device
The research group, led by Yi Cui, professor of materials science and engineering at Stanford, has created ink made from carbon nanotubes and silver nanowires. When the paper is dipped in the nano-enhanced ink and then baked, it transforms into a black paper that can act as a battery or supercapacitor. The ink-treated paper is able to hold an electric charge in any form, whether it lies flat or crinkled. Professor Cui notes that the ‘nano paper’ could have applications in electricity storage devices connecting to electrical grids, and could also be used in hybrid electric cars.
