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.
The simplest example of a capacitor consists of two conducting plates of area A , which are parallel to each other, and separated by a distance d, as shown in Figure 5.1.2. Experiments show that the amount of charge Q stored in a capacitor is linearly proportional to ∆ V , the electric potential difference between the plates. Thus, we may write
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
The fundamental design parameters available to the designer are controlled to a large degree by the environmental factors, such as temperature range, voltage, wave shape, pulse repetition rate (rep-rate), and duty cycle. Essentially all these environmental factors affect the life expectancy of the capacitor as shown schematically in Figure 2 .
The Review culminates with feasible future directions for the commercial success of hybrid ion capacitors, which are in the nascent stages of developments. To the best of our knowledge, it is the first holistic account of hybrid ion capacitors from their historical perspectives to present developments. The authors declare no conflict of interest.
7. CONCLUSIONS Modern capacitor technologies generally retain the potential for increased power and energy densities by factors of 2-10 times, depending upon the specific technology. Implementation of these potentially ever more compact designs rests primarily upon cost consideration in the consumer, commercial, and industrial sectors.
