Capacitors are fundamental in electrical systems, primarily for storing and releasing energy. They serve as essential components in electronics, power networks, and applications where temporary energy storage and stabilization are crucial. Additionally, capacitors play a key role in filtering, power conditioning, and circuit tuning.
[ 25 ] Dielectric capacitors and electrolytic capacitors are two common conventional capacitors. The medium of a dielectric capacitor is a dielectric material, which relies on the polarization of the dipole around the electrode and dielectric interface to store charge (Figure 2a).
Electrolytic Capacitor Electrolytic capacitors are capacitors that exist in two forms: non-polar and polar. The anode of these capacitors typically comprises metal foil, such as aluminum or tantalum, with an oxide film, often aluminum oxide or tantalum pentoxide, serving as the dielectric and adhering closely to the anode.
The conventional capacitors, as a passive electronic component, are composed of two adjacent conductors and an insulating medium between them. In 1745, the invention of the Leyden jar opened the door of capacitor technology. [ 21 ] Thereafter, a series of representative capacitors came out one after another.
Capacitors possess higher charging/discharging rates and faster response times compared with other energy storage technologies, effectively addressing issues related to discontinuous and uncontrollable renewable energy sources like wind and solar .
The competence of charge-storage for a capacitor is measured by the value of capacitance. As shown in Equation (1), the capacitance of a capacitor is proportional to the area between the electrode and the dielectric (A), and inversely proportional to the distance between the two plates (d).
