Lightscribe DVD burner used to to scale graphene supercapacitors

Posted at 18 March 2013 17:39 CEST by Jan Willem Aldershoff

Reseachers use  Lightscribe technology, found in commercial grade CD and DVD burners, to create graphene micro-supercapacitors. The technology is developed by the University of Los Angeles and the end results are  devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom–thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers.

To make it work they glued a  plastic layer on a DVD and then coated it with a layer of graphite oxide. By using Lightscribe they were able to use the laser of the DVD burner to create a so-called interdigitated pattern. Because Lightscribe is so precise all lines where seperated and didn’t touch eachother which would short-cicrcuit the supercapacitor. This means that for a relative low price and by using existing technology it’s possible to create a high-tech product.

The new micro-supercapacitors are highly bendable and twistable, making them potentially useful as energy-storage devices in flexible electronics like roll-up displays and TVs, e-paper, and even wearable electronics. A video with a more in-depth explanation can be found here.

    This is a wonderful idea. I've always believed that if an electric car would be made that would recharge in roughly the same amount of time that it takes to fill a gas tank, and with no excessive premium in cost for that ability, we'd be well on our way to a more useful electric vehicle.

    Now the only problem is how large a conductor will you need to carry the amount of charge that it would take to drive a car, oh, say, 300 miles into the super capacitor in just a minute. I'm guessing it would be somewhat larger gauge than your typical 15 A extension cord UNLESS it could be made of room temperature super conductor but that's a whole different field of research.
