But unlike a battery, the supercapacitor stores energy on the surface of each of these electrodes (as a capacitor would), not in chemicals. Meanwhile, a capacitor normally has a non-conducting gap between two conductors. In a supercapacitor, this gap is filled with an electrolyte. That would be similar to the gap between the electrodes in a ...
