Unlike batteries, electrochemical capacitors (ECs) can operate at high charge and discharge rates over an almost unlimited number of cycles and enable energy recovery in heavier-duty systems. Like all capacitors, ECs (also called supercapacitors or ultracapacitors because of their extraordinarily high capacitance density) physically store charge.
Customer ServiceElectrochemical capacitors are the electrochemical high-power energy-storage devices with very high value of capacitance. A supercapacitor can quickly release or uptake energy and can be charged or discharged completely in few seconds whereas in case of batteries it takes hours to charge it [7, 8].The working principle of ECs is same as that of a conventional
