New battery made from paper

New type of battery is coming. Researchers at Stanford University are using carbon nanotubes with silver nanowires to realize ink to be printed over a standard piece of paper and realize a a low-cost battery or supercapacitor that is ultra lightweight.

Professor Yi Cui said that this type of battery is more durable due to the fact that the ink adheres strongly to the paper. The paper supercapacitor may last through 40000 charge-discharge cycles.

The flexibility of the paper allows many practical applications like using it in electric or hybrid cars.

The experiment shown also in the video where focused on using paper battery to turn on a LED, which glowed brightly.



"This technology has potential to be commercialized within a short time," said Peidong Yang, professor of chemistry at the University of California-Berkeley. "I don't think it will be limited to just energy storage devices," he said. "This is potentially a very nice, low-cost, flexible electrode for any electrical device."
