[h=1]Graphene Nanoribbons Bring New Twist to Li-ion batteries[/h]
In the lab tests, the prototype battery had an initial charge capacity of more than 1520 milliamp hours per gram (mAh/g). After repeated charge-discharge cycles that number began to plateau at about 825 mAh/g......
While they aren’t technically batteries, supercapacitors could be the next big thing. Such a device could fully charge a smartphone or even an electric car in seconds

A startup spun out of Northwestern University, called SiNode Systems, is building a lithium ion battery using a piece of graphene drilled with tiny holes. The unusual structure can boost the amount of energy that a battery’s anode can hold by ten times, and can also enable the battery to be charged much more swiftly than conventional lithium ion batteries........http://gigaom.com/2013/04/29/holy-graphene-giving-batteries-a-boost-with-graphene-and-tiny-holes/
