Variable Super Capacitor.

5.5V 500F Super Capacitors in small size are available then why they have not made 500F variable Super Capacitors?

Probably no demand, even if it were possible to make. What would you use one for?
It would be great for designing a regenerative braking system.
You increase the capacitance to match the voltage, much like a syringe to suck up charge.
Then you decrease the capacitance to push out the charge.

After charging the plates, they want to attract . If we assume some sort of physical separation, to reduce capacitance between charged plates will require work..

Just for very quick charging DC power supplies for all kinds of devices where I can adjust the total capacitance of the series parallel combination of supercapacitor bank capacitanc as required.
