Supercapacitors are considered comparatively new generation of electrochemical energy storage devices where their operating principle and charge storage mechanism is more closely associated with those of rechargeable batteries than electrostatic capacitors.
There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors. Dielectric capacitors encompass film capacitors, ceramic dielectric capacitors, and electrolytic capacitors, whereas supercapacitors can be further categorized into double-layer capacitors, pseudocapacitors, and hybrid capacitors.
Most prominently, solar, wind, geothermal, and tidal energy harvesters generate electricity in today's life. As the world endeavors to transition towards renewable energy sources, the role of supercapacitors becomes increasingly pivotal in facilitating efficient energy storage and management.
In comparison to batteries, supercapacitors exhibit a superior power density and the ability to rapidly store or discharge energy . Nevertheless, their energy density is lower due to the constraints associated with electrode surface charge storage.
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 .
However, current supercapacitors can only store a low amount of energy, which limits their range of potential applications. If supercapacitors could be designed to store more energy, they would be physically lighter and charge much faster than batteries, which would have a significant commercial impact, according to scientists.
