A SPRAY-ON BATTERY HAS BEEN DEVELOPED

Greetings:

The word is that a spray-on battery has been developed by the science gurus.

The elements of the battery, the cathode and anode and separator have been incorporated into a liquid that can be sprayed-on, in layers; this development will probably yield the thinnest battery yet. I reckon this will enable the development of even smaller devices (perhaps coupled with a solar recharger); such as a spy camera on a shirt-button, ear-ring, nose-ring or even a shoe-phone.(Oh, yeah, where would we be without those TV shows)

Researchers at Rice University in Houston, Texas, have come up with a technique to break down each element of the traditional battery and incorporate it into a liquid that can be spray-painted in layers on virtually any surface.

"This means traditional packaging for batteries has given way to a much more flexible approach that allows all kinds of new design and integration possibilities for storage devices," said Pulickel Ajayan, who leads the team on the project.

The rechargeable battery is made from spray-painted layers, with each representing the components of a traditional battery: two current collectors, a cathode, an anode and a polymer separator in the middle.

The paint layers were airbrushed onto ceramics, glass and stainless steel, and on diverse shapes such as the curved surface of a ceramic mug, to test how well they bond.
