There is a consensus that the energy storage performance of capacitors is determined by the polarization–electric field (P – E) loop of dielectric materials, and the realization of high Wrec and η must simultaneously meet the large maximum polarization (Pmax), small remanent polarization (Pr) and high Eb.
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 .
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.
Electrolytic capacitors are known for their large capacitance and high volumetric efficiency, making them suitable for applications in electronic devices or as energy buffers. However, they suffer from drawbacks such as high equivalent series resistance (ESR) and relatively short service life.
More seriously, unsuitable experiment setup can even lead to incorrect evaluation of dielectric constant, one of the most important figure-of-merit, which can significantly affect the energy storage density of capacitors.
