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.
Anglo-Saxon Sword and Helmet from Staffordshire Hoard Reconstructed 2015-05-29 0:49
Thousands of metal fragments from the Staffordshire Hoard have been reconstructed into two "significant" new 7th Century objects.
Researchers have pieced together parts of a silver helmet and a previously unseen form of sword pommel.
The hoard, which is valued at ¬£3.2m, was found in a field near Burntwood, Staffordshire in July 2009.
Both items have been put on display at Birmingham's Museum ...
ALEC corruption: Legislators and corporate lobbyists meet in secret at Savannah resort 2015-05-28 23:59
The Georgia Legislature has a message for voters: don't ask us about our meetings with corporate lobbyists behind closed doors.
The 11Alive Investigators tracked lawmakers to a resort hotel in Savannah last week, where we observed state legislators and lobbyists mingling in the hotel bar the night before they gathered in private rooms to decide what new laws would best serve ...
Swedish politician: US is the true cause of the masses of refugees from the Middle East 2015-05-28 20:13
Editors Note: And who controls US foreign policy? Listen to Jeff Gates.
The present Swedish debate about war refugees from the Middle East is an example of peer restricted expression. In the name of political correctness or perceived decency, any questioning of maximum generosity in opening Swedish borders for the refugees is indignantly rejected by the official mainstream. We have a ...
Even if Patriot Act Expires, Government Will Keep Spying on All Americans 2015-05-28 19:52
Government Will Use "Secret Interpretations" to Get Around Legal Prohibitions
Mass surveillance under the Patriot Act is so awful that even its author says that the NSA has gone far beyond what the Act intended (and that the intelligence chiefs who said Americans aren't being spied on should be prosecuted for perjury).
Specifically, the government is using a "secret interpretation" of the ...
The TPP, Monsanto, Rockefeller, Trilateral Commission, Brzezinski 2015-05-28 19:18
All hands on deck for global, economic, corporate dictatorship
There are dots to connect here. They're real, and they're spectacular.
Let me begin with a brief exchange from a 1978 interview, conducted by reporter Jeremiah Novak. He was speaking with two American members of the Trilateral Commission (TC), a group founded in 1973 by David Rockefeller and his intellectual flunkey, Zbigniew Brzezinski.
