Graphene vs Lithium?

[Johneb]

Had heard about graphene batteries. How does this stack up against LifePo4?

Maxwell super capacitor 18v500f
1.long life: up to 8 million to 120 million cycles
2.High Power density: up 6700w/kg
3.Low ESR: can be used as a rechargeable battery and ideal for back up purposes
4.Quick charge: charging 10 seconds to 10 minutes to reach its rated capacity of more than 95%
5.Quality standard:ISO 9001:2000;ISO 9001:2008;ISO 14001:2004
6.Excellent service: ensure products quality,promise one year after-sold service,there is no worry for you

Nevermind. I found the other threads on these. So the gist of what I am getting is that they are great storage devices but do not have the same discharge of LifeP04 batteries. Maybe a bank of these to recharge lithium batteries? IF so what battery charger to use.
