Electrical energy is stored in supercapacitors via two storage principles, static double-layer capacitance and electrochemical pseudocapacitance; and the distribution of the two types of capacitance depends on the material and structure of the electrodes. There are three types of supercapacitors based on storage principle: [ 16 ][ 24 ]
These characteristics, together with their long-term stability and high cyclability, make supercapacitors an excellent energy storage device. These are currently deployed in a variety of applications, either in conjunction with other energy storage devices (mostly batteries) or as self-contained energy sources.
While supercapacitors and batteries serve distinct energy storage applications, they often share common material components, such as carbon-based materials. For instance, carbon nanotubes (CNTs), widely used in supercapacitors, have also been explored as electrode materials in batteries.
Supercapacitor specific power is typically 10 to 100 times greater than for batteries and can reach values up to 15 kW/kg. Ragone charts relate energy to power and are a valuable tool for characterizing and visualizing energy storage components.
Supercapacitors are energy storage devices that combine the high energy storage capability of batteries with the high power delivery capability of capacitors. They consist of two conducting electrodes separated by an insulating dielectric material, allowing them to store and release energy quickly.
Typical values of energy and power densities of commercially available supercapacitors are in the range of 4–5 Wh/kg and 10–20 kW/kg, correspondingly, but recent developments suggest that these figures can be overcome in the foreseeable future.
