#GRAPHENE: "Activated graphene boosts supercaps"

Brookhaven National Laboratory recently characterized activated graphene fabricated at the University of Texas-Austin, concluding that it had an power density that could rival batteries, at a quick-recharge rate that exceeded batteries, and a lifetime of at least 10,000 charge/discharge cycles.

Used instead of batteries, activated-graphene supercapacitors could last 27 years for a plug-in vehicle recharged once a day. The DoE also speculates that gigantic activated-graphene supercapacitors at power-stations could smooth out power availability from intermittent power, such as wind and solar.
