A team of researchers at Stanford University started with off-the-shelf copier paper, painting it with an "ink" made of carbon nanotubes.
The coated paper is then dipped in lithium-containing solutions and an electrolyte to provide the chemical reaction that generates a battery's electric current.
The paper acts to collect the electric charge from the reaction. Using paper in this way could reduce the weight of batteries, typically made with metal current collectors, by 20%.
