Breakthrough In Use of Graphene For Ultracapacitors
Hugh Pickens writes "Researchers at the University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick graphene for storing electrical charge in ultracapacitors. They believe their development shows promise that graphene could eventually double the capacity of existing ultracapacitors. 'Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well for the delivery of electrical current and, thus, electrical power,' says one of the researchers. Two main methods exist to store electrical energy: in rechargeable batteries and in ultracapacitors, which are becoming increasingly commercialized but are not yet well known to the public. Some advantages of ultracapacitors over traditional energy storage devices such as batteries include: higher power capability, longer life, a wider thermal operating range, lighter, more flexible packaging and lower maintenance. Graphene has a surface area of 2,630 square meters, almost the area of a football field, per gram of material."
If you wanted a thin layer of carbon, wouldn't it be easier just to toast the bagel?
Speaking of expanding..."Graphene has a surface area of 2,630 square meters, almost the area of a football field, per gram of material."... As a young man I plugged a large 12v capacitor into a 240v outlet because I thought....hmmm....if a 9v battery make that big a spark....Ten minutes later I had it screwed to a wooden booard with a domestic power cord attached....KABOOM!!!....my room was covered in sticky silvery confetti...you get where I'm going, graphene would go off like a fuel air bomb! All this leads me to the conclusing that .....
/sorry
If you car has a graphene ultracapacitor, resources consume you!

Yes, a lot of it was just hiding behind Hydrogen atoms, so you couldn't see it.

What, doesn't everybody like that stuff?
