Yi Cui, a researcher from Stanford and his team have succeeded making office paper into an electrode by dipping it into nanotube ink. The resulted dipped paper becomes a strong, flexible and highly conductive material that could be incorporated into lightweight batteries or serving as an electrode in high-energy ultracapacitors. The nanotube-treated paper can store much more energy than classic batteries.
