Capacitors form a technology that permits electrical energy to be stored over a long charging time and then released as required over short (submicroseconds to multimilliseconds) periods and under controlled conditions. Modern capacitor technologies generally retain the potential for increased power and energy densities by factors of 2–10 ...
For example, surface area in ceramic capacitors was increased through the development of advanced processing methods for barium titanate—the true application of nanotechnology and a major success in the sales and marketing of an advanced technology breakthrough. A radical improvement in the effective capacitance per gram of ceramic capacitor.
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 .
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.
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 .
