U.S. researchers printed, yes, printed a battery and they’re looking to scale up the process to run devices from pacemakers to pickup trucks with batteries printed on a printing press. Rensselaer Polytechnic Institute’s team published a description in the Proceedings of the National Academy of Sciences of how they’ve printed a foldable, rollable, cuttable paper battery a little bigger than a postage stamp that stores enough power to run an LED light.
