Dribble as usual was extrapolating too far without actually thinking
through the implications.

While a high capacity super cap would be good new for all sorts of
electronic gadgets, it would simply bring a different problem should you
apply it to (longer range) transport.

If you have a 50kWh battery and want to charge it, what charge rate do
you need to use to charge it in a minute (or even ten)?



(there are actually some even more interesting developments using hybrid
LiPoly batteries with carbon nano tubes to increase capacity)


NOT to increase capacity. To decrease internal resistance. faster
charging, no more miles per charge.

That statement seems mutually contradictory...

Even just a reduction in internal resistance would make more of the
stored energy usefully available, and result in less dissipation in the
cell itself.

However what I was reading also suggested an increase in capacity as well:
