Could the Super Capacitor replace batteries?

Ever needed to go out and realised you haven't charged your phone? No problem, plug it in for 30 seconds and you are good to go. 

The below video discuss a new technology discovered by a couple of guys in UCLA on using graphene to store electricity like a battery, but unlike a battery it can charge within minutes.

If they can scaled this up, just imagine the possibilities. We can harness solar and wind energy and store them in these super capacitors and use the electricity when we need it. We can have electric cars that charges in minutes. And the best of all it is just carbon, so it friendly to the world. 

I recommend you watch the below video, and if you have seen it watch it again :-)
