"Paper Battery Shows Promise for Grid, Vehicle Energy Storage"
"Ordinary office paper coated with an inky layer of carbon nanotubes or nanowires can make a lightweight, flexible and highly conductive battery or superconductor, according to Stanford University researchers.
The scientists had previously experimented with making batteries using a similar process of painting nanomaterial ink onto a thin layer of plastic. But in an unexpected twist, they found that pores in paper fibers make it hold the ink better than plastic, for a more durable battery.
The research, led by nanomaterials science and engineering researcher Yi Cui, was described this week in the Proceedings of the National Academy of Sciences."
