Electrochemical double-layer capacitors (EDLCs) are devices allowing the storage or production of electricity. They function through the adsorption of ions from an electrolyte on high-surface-area electrodes and are characterized by short charging/discharging times and long cycle-life compared to batteries.
An electrical double layer capacitor is used to compensate for electricity until another source is connected. The electrical double-layer capacitors utilized in energy fluctuation sources are known as energy equalization. Some power plants generate electricity using green energy, which is subject to natural changes.
According to the energy-storage mechanism, electrochemical capacitors can be divided into two types: electrochemical double-layer and redox supercapacitors . In the former, the electric double layer capacitors (EDLCs) are based on the double-layer capacitance at the solid/solution interface of the high-surface-area materials.
Pseudocapacitors are another type of electrochemical capacitor that exists in addition to EDLCs. In contrast to the electrostatic nature of opposite charges in double-layer capacitors (EDLCs), Faradaic charge transfer happens between electrolyte (e.g., xyz materials) and electrode (e.g., xyz materials) in pseudocapacitors.
A more recent example is the use of electrochemical double layer capacitors (EDLCs) in emergency doors (16 per plane) on an Airbus A380, thus proving that in terms of performance, safety and reliability ECs are definitely ready for large-scale implementation.
As a part of this renewed interest in electric double-layer capacitors (EDLCs), researchers began seeking new strategies to synthesize high surface area porous carbon-based materials as electrodes for EDLCs to obtain high specific capacitance and high energy density.
