scientists say paper battery could be in the works - energy storage devices
Washington, December 7Reuters)-
One day, regular paper can be used as a light battery to power devices that now make printed text covered by emailmail, e-
Books and online news.
Scientists at Stanford University in California reported on Monday that they have successfully turned paper coated with silver and carbon nano-material ink into a "paper battery" that is expected to become a new type of light weight, high
Performance energy storage.
The same function that helps ink to attach to paper allows it to remain single
Carbon nanotubes and silver nanoparticles.
Early studies have found that silicon nanoparticles can be used to make batteries 10 times more powerful than lithium.
Now, ion batteries have been used to power devices such as laplop computers.
"Low cost, light and high cost with mature paper technology
Performance Energy-
Storage is achieved by using conductive paper as a current collector and electrode, "scientists said in a study published in the Journal of the National Academy of Sciences.
Scientists say the battery can power electric or hybrid cars, make electronics lighter in weight and longer in life, and may even lead to paper electronics one day.
Battery weight and life have been obstacles to the commercial viability of electric vehicles
Power cars and trucks.
"Society really needs a lowcost, high-
Performance energy storage devices, such as batteries and simple super capacitors, "assistant professor of materials science and engineering, Stanford University
Said the author Cui Yi.
Cui said in an email
In addition to being useful for portable electronics and wearable electronics, "our paper super capacitors can also be used in a variety of applications that require instant high power.
"Because the cost of our paper batteries and super capacitors is very low, they are also good for the grid --
"Connect energy storage," he said.
Yang Peidong, professor of chemistry at the University of California-
Berkeley said the technology could be commercialized in a short time. (
