The price per unit of energy (kWh) is extremely high. Energy accumulation and storage is one of the most important topics in our times. This paper presents the topic of supercapacitors (SC) as energy storage devices. Supercapacitors represent the alternative to common electrochemical batteries, mainly to widely spread lithium-ion batteries.
Classification of supercapacitors has been discussed. Supercapacitors are considered comparatively new generation of electrochemical energy storage devices where their operating principle and charge storage mechanism is more closely associated with those of rechargeable batteries than electrostatic capacitors.
The working principle of the supercapacitor As shown in Figure 1, the supercapacitor is mainly composed of many parts, like current collectors, electrodes, electrolytes, and separators. The role of the separator has the same function as the separator in the battery.
Supercapacitor is an electrochemical capacitor that has high energy density and better performance efficiency as compared to the common capacitor, the reason why it has the prefix ‘super ’attached to it. It stores and releases energy by reversible desorption and adsorption of ions at the electrode-electrolyte interface.
Charges are electrostatically stored in supercapacitors. An electric field is generated at each electrolyte as soon as the voltage is applied across the terminals which leads to the polarisation of the electrolyte. As a result of which ions diffuse through the dielectric to the porous electrodes of opposite charges.
