Nanopore Structure Could Lead to Miniaturization of Energy Storage Components
Researchers at the University of Maryland have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components. The structure is called a nanopore: a tiny hole in a ceramic sheet that holds electrolyte to carry the electrical charge between nanotube electrodes at either end. The existing device is a test, but the tiny battery performs well. Ph.D. student Chanyuan Liu says that it can be fully charged in 12 minutes, and recharged thousands of time. Many millions of these nanopores could be crammed into one larger battery the size of a postage stamp.
