The surface area of the plates of a supercapacitor is relatively more, while the distance between the two plates is less as compared to that of normal electrolytic capacitors. Supercapacitors are advantageous as they are durable, have a long life span, and do not easily get affected by wear and tear.
The charge distribution has a certain relationship with the fast rate of charging and discharging and the life of the capacitor. The study found that it is precisely due to the existence of this solvation phenomenon that the supercapacitor cannot achieve full discharge under high power.
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.
In order to deeply understand the energy storage mechanism of supercapacitors and optimize the performance of supercapacitors, it is usually necessary to use two experiments, the cyclic voltammetry curve, and the constant current discharge to characterize the electrode performance of the different supercapacitor.
In this context, the super capacitors, as an energy storage technology, possesses excellent performances such as high power density, maintenance-free, and long life, and it have become the focus of attention in academia and industry. This section mainly will introduce the electrochemical mechanism of supercapacitors.
Static electricity is used in these capacitors to store energy. These capacitors produce positive and negative charge ions between the two plates in the electrolyte solution. This is because in the presence of a voltage supply, one plate develops a positive charge, and the other develops a negative charge.
