Graphene-based supercapacitors produced at UCLA

Power 1

muon-catalyzed (2483394) writes "Researchers at UCLA have successfully produced high-performance graphene-based supercapacitors using a computerized LightScribe DVD drive. These devices exhibit ultrahigh energy density values in different electrolytes approaching those of batteries, yet they can be charged in seconds. The devices can be charged and discharged for more than 10,000 cycles without losing much in performance compared with a normal life-time of less than 1000 cycles typical for batteries. Imagine having an energy storage device that stores as much energy as a conventional battery (YouTube video), yet, can be charged 100 to 1000 times faster."

Top Job (1)

A nonymous Coward (7548) | about a year and a half ago | (#43194957)

Wasn't Top Job the early James Bond villain who flung sharp edged top hats at people to kill them?

I have visions of him flinging sharp DVDs which not only decapitate but also electrocute.
