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.
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 .
High-entropy (HE) ceramic capacitors are of great significance because of their excellent energy storage efficiency and high power density (PD). However, the contradiction between configurational entropy and polarization in traditional HE systems greatly restrains the increase in energy storage density.
These capacitors exhibit extremely low ESR and equivalent series inductance, coupled with high current-handling capabilities and outstanding high-temperature stability. As a result, they show immense potential for applications in electric vehicles, 5G base stations, clean energy generation, smart grids, and other fields.
Aluminum electrolytic capacitors (AECs) offer a superior cost-to-energy ratio and volume efficiency compared with various other capacitor types . As a result, they are frequently employed at the dc-link of power electronic converters (PECs) to serve as an energy buffer .
The introduction of battery-type materials into the positive electrode enhances the energy density of the system, but it comes with a tradeoff in the power density and cycle life of the device. Most of the energy in this system is provided by the battery materials, making it, strictly speaking, a battery-type capacitor. 4. Summary
