Need to come up with specifications for a capacitor that can hold 20,000 or more amps
How many joules or watts or how much energy can this theoretical capacitor hold
how many farads, what would the current be and how many volts could it tolerate, how to increase volt tolerance. how to increase charge rate, decrease charge time?

how much surface area would be needed for the electrodes, thinking of hafnium as a electrode and thinking of teflon as a insulator since it has a dielectric strength of 60x10^6, but it melts around 650 degrees. is there something else with a high dielectric strength but higher melting point? any input on these questions is greatly appreciated

Your questions start of with a nonsensical one. Capacitors don't hold amps. This is like asking how big a gas tank has to be in order to go 200 mph.

You might take a step back and first learn what a capacitor is and what it does and how it does it.

All of your questions except the last one are based on the answer to the first one and it has no answer because it is completely nonsensical.

The last one, regarding dielectric strength, is unanswerable because you don't bother to give the units on your dielectric strength. This is like asking if anyone knows where you can get steel pipe that is more than 8 long.

But if you want a high dielectric strength material that has a high melting point, try fused silica.

An amp takes one whole second. Do you need the whole second?

Why do you ignore the answer given to you in post #2? Not polite at all and stupid. You could learn from there enough to answer your own question.
