Nanobatteries — Safer By Design

Iddo Genuth writes "Conventional Li-Ion batteries have been known to catch fire and explode. A new, safer type of Li-Ion nanobattery that might help prevent such mishaps has been developed by researchers at Tel Aviv University. These nanobatteries should prove useful for various micro devices used for medical, military, and a range of other applications. They are 2-4 years from commercial availability."

Hardly a nanobattery

FTFA:

Using a silicon or glass substrate, the team from TAU created a matrix of tiny holes each 50 microns in diameter and 500 micron deep.

Atoms are on the order of a nanometer in diameter. These batteries are hundreds of thousands of times larger. Hell, you could probably hook these up with current chip lithography techniques (they're doing tens of microns now). Interesting microbattery, but let's keep the nanotech hype out of it.
