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 bitsy battery performs well. First author Chanyuan Liu, a graduate student in materials science & engineering, says that it can be fully charged in 12 minutes, and it can be recharged thousands of time.

A team of UMD chemists and materials scientists collaborated on the project: Gary Rubloff , director of the Maryland NanoCenter and a professor in the Department of Materials Science and Engineering and in the Institute for Systems Research; Sang Bok Lee, a professor in the Department of Chemistry and Biochemisty and the Department of Materials Science and Engineering; and seven of their Ph.D. students (two now graduated).
