As a result, on the positive electrode, there is an accumulation of negative charges which is attracts by positive charges due to Coulomb’s force around the electrode and electrolyte. Electrolyte–electrode charge balancing results in the formation of an EDL.
Charge storage mechanisms for electric energy storage (EES) devices and the types of EES devices with their characteristic electrochemical behavior. (A) Schematic descriptions of the four major mechanisms: the electrical double-layer formation, the bulk redox reaction, the surface near redox reaction, and the redox activity of the electrolyte.
As the energy storage device combined different charge storage mechanisms, HESD has both characteristics of battery-type and capacitance-type electrode, it is therefore critically important to realize a perfect matching between the positive and negative electrodes.
Over recent decades, a new type of electric energy storage system has emerged with the principle that the electric charge can be stored not only at the interface between the electrode and the electrolyte but also in the bulk electrolyte by redox activities of the electrolyte itself.
In particular, the classification and new progress of HESDs based on the charge storage mechanism of electrode materials are re-combed. The newly identified extrinsic pseudocapacitive behavior in battery type materials, and its growing importance in the application of HESDs are specifically clarified.
