How to Make a Battery Out of Office Paper & Nanotubes

Stanford University researchers think they've stumbled upon a way to transform ordinary sheets of office paper into batteries and superconductors. By painting a carbon nanotube ink, which can collect electric charge, on plain copier paper, and then dipping the coated paper into a lithium ion solution and an electrolyte, they can create a current and store it within the paper battery. 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 New York Times
