The basic principle of supercapacitor energy storage is to store electrical energy through the electric double-layer capacitance formed by the charge separation on the interface between the electrolyte and the bath solution. Figure 1: Schematic diagram of supercapacitor structure and working principle Ⅱ. The energy storage mechanism
A supercapacitor is an advanced energy storage device that offers high power density and has a long cycle life. These devices store energy through the separation of charge in an electrolyte, rather than through the chemical reactions used in batteries. This technology has undergone extensive developments in the last few years.
A schematic diagram depicts the development of modern supercapacitor devices and their potential components. (reproduced with permission granted from ref. ). The cycle-life (or lifetime) and energy density of electrochemical energy devices are the other two factors to consider while evaluating them.
