Well, I read the whole thread.
There is confusion capacitor / supercapacitor. A supercapacitor is technically different from different types of capacitors and it is also a pity that another name has not been given, because many are confusing.
When a capacitor uses planar frames, a supercapacitor uses micro-porous electrodes.
A supercapacitor uses an electrolyte that literally impregnates the electrodes with its ions that enter the electrode whose surface is increased thanks to the micropores.
So there will never be a supercapacitor designed with an electrode consisting of a single layer of flat graphene. It would not be efficient at all and not a supercapacitor.
On the other hand, one can use full layers of graphene separated by the electrolyte or carbon nanotubes, to allow the ions to return deeply within the electrodes and to increase the useful surface of the electrode and thus to increase the density of energy .
Schematically, it gives that:
Obviously this is not easy to make, so for now the SkelCaps are actually not quite made from graphene but with "Carbon Derived from Carbide (CDC), which can effectively be represented as an assembly of curved graphene flakes. "
The CDC looks like this:
Obviously, a dielectric used for an electrode an atom thick would rot. But an electrode will never make an atom thick, even "based" on graphene.
Moreover, all scientific results with electrodes not at least 100 microns thick are not considered significant.

Anyone wishing to talk about a supercapacitor should first read this big issue about supercapacitors:

There are really a lot of explanations, and it's exciting.
