Scientists in the United States have developed a paint that can store and deliver electrical power just like a battery.
Traditional lithium-ion batteries power most portable electronics. They are already pretty compact but limited to rectangular or cylindrical blocks.
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.
One limitation of the technology is in the use of difficult-to-handle liquid electrolytes and the need for a dry and oxygen-free environment when making the new device.

US general who opened Guantanamo prison says shut it down 2013 12 12
The US general who opened the notorious US-run Guantanamo prison says it was a mistake and it should be shut down because the prison complex "validates every negative perception of the United States."
"In retrospect, the entire detention and interrogation strategy was wrong," Marine Major General Michael Lehnert wrote in the Detroit Free Press on Thursday.
Lehnert was the first commander of ...
BioSuit: The Future of Space Gear 2013 12 12 New materials and designs could allow outer-space travelers to move more freely.
One day, moving around in outer space—and walking on Mars—could become a whole lot more comfortable for astronauts, thanks to the innovative techniques being developed by an aeronautics professor at MIT.
