The researchers in March 2012 showed on the Web how they could spray a carbon substance onto the surface of a DVD, put that DVD into a DVD burner just like the ones found in nearly every modern PC, and out would pop a custom printed graphene supercapacitor: a layer of carbon one-atom thick capable of absorbing and holding onto an electric charge, like the chemical batteries we use in everything today, only much lighter and with much faster charging times. As with all of these so-called miracle breakthroughs that we hear are going to revolutionize the way we live, this massive discovery needs time for more research to bring it from a laboratory to a factory, and to solve all the associated scaling and production issues. Now the researchers are back with a progress update, and the production process has gotten easier and faster, while the supercapacitor has grown in capacity. "We are now looking for industry partners to help us mass-produce our graphene micro-supercapacitors," said Richard Kaner, a member of the California NanoSystems Institute at UCLA and a professor of chemistry and biochemistry. Numerous potential benefits from the product are making all sorts of industries excited by the technology's capabilities. Theoretically, once developed, the capacitors could hold the same charge as your cellphone battery, but fully charge in only a few seconds. An electric car could become charged in one minute. Solar panel manufacturers are interested in the possiblity of putting the thin sheets on the back of solar panels, to hold energy gathered during the day and to be used at night or during peak hours. Because of how thin they are, the supercapacitors are flexible, able to bend in half. They could be put anywhere, on a sticker. Your pants could keep your phone charged. While good progress is being made, we still aren’t there, though. But maybe one day soon, when we all give up on physical media, the DVD burners in our PCs can be turned into battery factories. Some guys in California did it.

(Yes, yes… I know. Republicans don’t care about science, but this may turn out to be important for your smart phone. More on that later.) Some of the great scientific breakthroughs of the last century came about entirely by accident. Many of you are probably familiar with the origins of the Post It Note, and how it was invented as a result of a failure when attempting to create a super strong adhesive. Well, there may be another such story taking place in the present day. Scientists working with carbon compounds developed Graphene, a safe substance with a lot of structural strength for very little mass and weight. And then some wise guy discovered that it had another use. - 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. That last sentence may sound pretty complicated, but the article’s author provides a translation for the layman. - He painted a DVD with a liquid carbon solution and stuck it into a standard-issue DVD burner. The result was a shockingly thin supercapacitor which could store up a large amount of electrical energy in no time flat. The potential for this sort of discovery should be obvious. Unlike heavy metal batteries, the carbon compound is biodegradable and cheap to manufacture. And a battery made of layers of this material could charge your cell phone for a full day’s use in – wait for it – two seconds. A ramped up version could charge an electric car in a minute or two. (No word on how likely it will be to catch on fire, but bonus points if it doesn’t.) Here’s the video I mentioned. It’s not long and explains the process better than I ever could. I have to say, this is pretty exciting stuff if it comes to fruition. [video] The Super Supercapacitor | Brian Golden Davis from Focus Forward Films on Vimeo.
