They have two electrodes, an anode and a cathode, that are connected by an electricallyconductivematerial—generally a liquid—called an electrolyte.

"You need an electricallyconductivematerial for a capacitor, and diamonds are insulators," said Olga Shenderova, a nanodiamond expert at the International Technology Center in North Carolina.
An electricallyconductivematerial which is inert in the fluid environment is a desirable material of construction for the electrical field plates of the "water capacitor" employed in the circuit.
