RE: [Vo]:10,000 Farads Graphene Supercapacitor
Jones:
I've seen recent articles about success in manipulating graphene to transition
between conductive and nonconductive states... it being a good dielectric
might be in the cards... and perhaps it also depends on the orientation of the
internal E and/or B-fields.

Just checked and the EEStor site is still up. I thought they had gone under.
http://www.eestor.us/index.html
Zenn is apparently still active as well (Canadian- so they probably went
through another round of stock manipulation).
Despite the UCLA connection to Sunvault and the convincing videos - there is
too much which is unsaid in this sales pitch. It can be argued that it is
trickery to promote any capacitor design as "graphene" since the important
thing for ultra-capacitance is the dielectric, no? Graphene is a conductor, so
what is the dielectric being used with the graphene? Please do not say:
modified barium titanate.
Obviously, graphene gets a lot of good press - "graphene fever" is kinda like
"nano fever" of 5 years ago and hydrogen fuel-cell fever before that (Ballard
still survives). The pump-and-dumpers of BC are on track to reinvent that same
investment fever.
EEStor at least did have testable material. Never mind that in a rear-ender, a
high voltage ultracapacitor could be the equivalent of a rather formidable
bombe, as the inspector would say. Yet --- to put this story into perspective
... recently mentioned here on Vo was the so-called "megafarad" cap ... isn't
that one positioned to be a two orders of magnitude bigger bombe? (not to
mention, the technology turns out to be already 6 years old but the product is
vaporware).
The hyperbole and "revised" data of Canadian energy stocks makes Parkhomov look
like a choir boy... amazing the DGT could not plug in.

Building large 10kF capacitors is easy. It's making them small that is
difficult. :-)
Leakage rate and structural integrity are not mentioned and are the biggest
weaknesses in SCap design (as EEStor found out).
