Capacitive charge storage is well-known for electric double layer capacitors (EDLC). EDLCs store electrical energy through the electrostatic separation of charge at the electrochemical interface between electrode and electrolyte, without involving the transfer of charges across the interface.
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.
A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates.
The mechanism of charge storage in electrochemical capacitors has traditionally been attributed to the electrosorption of ions on the surface of a charged electrode to form an electrical double layer 16.
Charge storage in supercapacitors is characterized by voltage-dependent capacitance and energy density. The differential capacitance of an electrode is defined as the derivative of the electrode’s charge with respect to its potential (Methods and Supplementary Section 2).
The pursuit of energy storage and conversion systems with higher energy densities continues to be a focal point in contemporary energy research. electrochemical capacitors represent an emerging class of electrochemical energy devices that bridge the gap between conventional capacitors and batteries.
