Graphene capacitors charge 100 times faster than batteries

Graphene battery
UCLA researchers are claiming that they have found a way to increase the amount of energy that can be stored on an electrochemical capacitor. These new supercapacitors use graphene electrodes which according to UCLA researchers have “excellent electrochemical attributes under high mechanical stress.” The researchers are claiming that the new supercapacitors with the graphene electrodes store just as much energy as current batteries but can “be charged and discharged a hundred to a thousand times faster” than their normal counterparts. The graphene electrodes were made by “coating a DVD disc with a film of graphite oxide that is then laser treated inside a LightScribe DVD drive to produce graphene electrodes.
