The electric field normally exists in a dielectric which becomes polarised. The capacitance is proportional to the permittivity of the dielectric and the area of the plates, and inversely proportional to the separation distance of the plates. There is no intervening dielectric material in a supercapacitor. Most of the potential is dropped across the double layers, not a dielectric. Supercapacitors have a much higher capacitance than traditional capacitors because of the large equivalent area of the plates and the small effective separation distance of the plates. One gram of the electrode material can have an equivalent area of 2000m2, and the separation distance between an electrode and the layer of ions, the double layer, is in the nanometre range. Fig. 1 shows one cell of a typical carbon double layer supercapacitor. The physical construction is similar to that of a battery, with two electrodes immersed in an electrolyte and a separator between them. Unlike a battery however, there is no chemical energy storage. Within each supercapacitor, there are effectively two capacitors in series, each consisting of a carbon electrode and the adjacent layer of ions in the electrolyte. The ions are free to move anywhere within the electrolyte, penetrating the pores of the carbon electrodes and p […]
