Pretty exciting stuff!
The battery has always been the bottleneck in everything from cell phones to electric cars.
We will see if this is the leap forward that is bound to happen sooner or later.

A Feb. 21, 2013 article in Rewire reports on a breakthrough in power storage that hold the promise to change the world. Researchers at UCLA have found a way to create what is in effect a super capacitor that can be charged quickly and will hold more electricity than standard batteries. What’s more, it is made with Graphene, a simply carbon polymer that, unlike batteries that have toxic metals in them, is environmentally benign and is not only biodegradable but compostable.
The researchers expect that the manufacturing process for the Graphene super capacitor can be refined for mass production.
The real world applications of an energy storage device that can be charged quickly and can hold as much if not more electricity as batteries is mind blowing.
For instance, electronic devices such as cell phones and tablet computers can be charged in seconds and not for hours and would hold a charge for longer than devices with standard batteries. This will diminish those annoying instances when one’s device suddenly goes dead for lack of energy.
Eventually the technology can be scaled up for electric cars or storage devices for wind turbines and solar collectors. Currently it takes hours to charge up an electric car. Such vehicles would become more viable if one can “refuel” them as quickly as one can a gasoline powered car.
This is all predicated on the notion that the technology lives up to its promise and doesn’t have a flaw, as yet uncovered, that will undermine it. In the meantime the UCLA researchers are looking for an industrial partner to build their super capacitor units on an industrial scale.

More Good News About The 'Scientific Accident That May Change The World'

That battery life video that had gone viral due to a recent post on UpWorthy (and which we told you about Tuesday) now has an update. We told you that researchers at Ric Kamen's lab at UCLA had found a way to make a non-toxic, highly efficient energy storage medium out of pure carbon using absurdly simple technology. Today, we can report that the same team may well have found a way to make that process scale up to mass-production levels.
The recap: Graphene, a very simple carbon polymer, can be used as the basic component of a "supercapacitor" -- an electrical power storage device that charges far more rapidly than chemical batteries. Unlike other supercapacitors, though, graphene's structure also offers a high "energy density," -- it can hold a lot of electrons, meaning that it could conceivably rival or outperform batteries in the amount of charge it can hold. Kaner Lab researcher Maher El-Kady found a way to create sheets of graphene a single carbon atom thick by covering a plastic surface with graphite oxide solution and bombarding it with precisely controlled laser light.
English translation: He painted a DVD with a liquid carbon solution and stuck it into a standard-issue DVD burner.
The result: Absurdly cheap graphene sheets one atom thick, which held a surprising amount of charge without further modification.
That work was reported a year ago; we mentioned it due to the video virally making the rounds this week. Late Tuesday, UCLA announced that El-Kady and Kaner have a new article in press, in the upcoming issue of Nature Communications, describing a method by which El-Kady's earlier, slightly homebrewed fabricating process shown in the video can be made more efficient, raising the possibility of mass production. As the authors say in their article abstract,
More than 100 micro-supercapacitors can be produced on a single disc in 30 min or less
