Bing Hu, a post-doctoral fellow at Stanford, prepares a small square of ordinary paper to with an ink that will deposit nanotubes on the surface that can then be charged with energy to create a battery. The flexibility of paper allows for many clever applications. “If I want to paint my wall with a conducting energy storage device,” says lead researcher Yi Cui, “I can use a brush.”
STANFORD (US)—Dip an ordinary piece of paper into ink infused with carbon nanotubes and silver nanowires, and it turns into a battery or supercapacitor. Crumple the piece of paper, and it still works. Continue…
