Abstract. Electrochemical capacitors (EC) also called ''supercapacitors'' or ''ultracapacitors'' store the energy in the electric field of the electrochemical double-layer. Use of high surface-area electrodes result in extremely large capacitance. Single cell voltage of ECs is typically limited to 1–3 V depending on the electrolyte used.
