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.
In terms of energy storage capability, the commercially accessible supercapacitors can offer higher energy density (e.g., 5 Wh kg −1) than conventional electrolytic capacitors, though still lower than the batteries (up to ≈1000 Wh kg −1).
Due to the challenges mentioned aforementioned, batteries alone cannot offer a comprehensive solution for energy storage. Electrostatic capacitors can also be used for energy storage applications. [25 - 29] The power density of electrostatic capacitors is extremely high (≈10 6 –10 7 Wh kg −1).
Electrochemical capacitors are known for their fast charging and superior energy storage capabilities and have emerged as a key energy storage solution for efficient and sustainable power management.
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 .
Optimizing manufacturing processes and technologies is a highly effective strategy for enhancing the storage capacity of electrochemical capacitors. However, in the long term, the discovery of new electrolyte and electrode materials with superior electrochemical performance becomes both crucial and challenging.
