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.
Better Identification of Viking Corpses Reveals: Half of the Warriors Were Female 2015-04-25 4:52
Shieldmaidens are not a myth! A recent archaeological discovery has shattered the stereotype of exclusively male Viking warriors sailing out to war while their long-suffering wives wait at home with baby Vikings. (We knew it! We always knew it.) Plus, some other findings are challenging that whole ârape and pillageâ thing, too.
Researchers at the University of Western Australia decided ...

Into Eternity - Finland's 100,000 Year Massive Underground Spent Nuclear Fuel Program 2015-04-24 20:49
Into Eternity is a documentary about a deep geological repository for nuclear waste. The concept of long-term underground storage for radioactive waste has been explored since the 1950s. The inner part of the Russian doll-like storage canisters is to be composed of copper. Hence in the case of Onkalo it is tightly linked to experiments on copper corrosion in running ...
