The specific capacitance is determined from the relationship between charge transferred from the current vs time plot or the slope of the potential vs time plot shown in Fig. 4 in the desired operating potential window.
Supercapacitor characterization and performance analysis are carried out using cells designed in either a two-electrode (Fig. 1 a) or three-electrode configuration (Fig. 1 b). Two-electrode systems are implemented to characterize cells while simulating real operating conditions.
For supercapacitors with an ideal electrostatic surface capacitive charge storage mechanism, the average charge is used in obtaining the specific capacitance (Eq. 12).
The capacitance of a supercapacitor originates from surface electrostatic interactions and or faradaic reactions as in pseudocapacitors, based on the charge storage media undertaken . Assuming no faradaic reactions and from first-order principles, the double-layer capacitance originating from surface interactions is expressed by Eq. 1.
Specific power is a measure of the speed at which energy can be stored or given off when needed. Supercapacitors electrostatic surface charge storage mechanism ensures that the latency associated with charge storage in batteries by virtue of chemical reactions is avoided, and thus the power is only affected by the internal resistance.
Capacitance (measured in Farads) is the ratio of the amount of electric charge stored on a material to the difference in electric potential applied. The capacitance of a supercapacitor originates from surface electrostatic interactions and or faradaic reactions as in pseudocapacitors, based on the charge storage media undertaken .
