Tiny Batteries Could Revolutionize Green Energy

Nanotechnology could dramatically improve energy storage for electronics, cars, and buildings.

Nanosize batteries that are 80,000 times thinner than a human hair represent a promising new front. They could advance the use of electric vehicles, now limited by short driving ranges, and of renewable energy, which needs storage for times when the wind doesn't blow or the sun doesn't shine.

The latest breakthrough: a "nanopore" that's the ultimate in miniaturization. It's a hole in a ceramic sheet, no thicker than a grain of salt, that contains all the components a battery needs to produce electric current. One billion of these holes, connected in a honeycomb fashion, could fit on a postage stamp.

The itty-bitty battery delivers. It fully charges in 12 minutes and recharges thousands of times, according to University of Maryland researchers, who published their findings last week in the peer-reviewed journal Nature Nanotechnology.

"We were blown away by the performance," says co-author Eleanor Gillette, a doctoral candidate in chemistry. She attributes its quick charging to the short distances needed to carry the electric current. She says the nanosizing could enable manufacturers to squeeze many batteries into a tight space.
