Energy storage: Capacitors can store electrical energy, making them useful in various applications. For example, they are often used in power supplies to smooth out voltage fluctuations, and they are also used in some electric vehicles to store energy from regenerative braking systems.
Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
Electrochemical capacitors, also known as supercapacitors, are becoming increasingly important components in energy storage, although their widespread use has not been attained due to a high cost/performance ratio. Fundamental research is contributing to lowered costs through the engineering of new materials.
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 .
Structural capacitors are structural materials (commonly polymer-matrix structural composites) that have been modified in order to render the capacitor function for the purpose of electrical energy storage. They are a type of multifunctional structural material.
Due to the strong effect of the composite fabrication method on the structural capacitor performance, the structure development should be performed with the involvement of composite engineers. Structural development should be conducted with inclusion of the electrical contacts in the overall design.
The modification of a structure to render the capacitor function involves the positioning of a dielectric film between the electrodes, which are an electronic conductor, commonly the continuous carbon fiber laminae that serve to reinforce the composite.
