Electrical double-layer capacitors (EDLCs, also known as supercapacitors or ultracapacitors) store energy by electrosorption of ions at the electrode/electrolyte interface. In addition, to achieve a high-energy storage capacity, electrodes with a high surface area and well-developed pore structure in the range from several Angstroms to several tens of nanometers are required.
