    supercaps are a complicated chemical structure, not just metal-insulator.

    here is an excerpt from the reference:

    Electrochemical capacitors (supercapacitors) consist of two electrodes separated by an ion-permeable membrane (separator), and an electrolyte ionically connecting both electrodes. When the electrodes are polarized by an applied voltage, ions in the electrolyte form electric double layers of opposite polarity to the electrode's polarity. For example, positively polarized electrodes will have a layer of negative ions at the electrode/electrolyte interface along with a charge-balancing layer of positive ions adsorbing onto the negative layer. The opposite is true for the negatively polarized electrode.

    Additionally, depending on electrode material and surface shape, some ions may permeate the double layer becoming specifically adsorbed ions and contribute with pseudocapacitance to the total capacitance of the supercapacitor.

    The best metal is silver. It is the most conductive both electrically and thermally, so it distributes the charge rapidly and conducts heat out but it is also expensive.

    Silver caps are used by the military, NASA,  high end computer and Audio systems.

    ANY METALS HAVE THE SAME CAPACITANCE EFFECT, COMMON USE TIN OR ALUMINIUM.
