Originální abstrakt

The charge in supercapacitor is stored on electrodes and in electrolyte. The charge on electrodes create the Helmholtz double layer which is formed immediately with time constant of the order of seconds, while the charge storage in electrolyte is going on with time constant of the order of hundreds seconds. When the charged supercapacitor is shorted for few seconds, the charge from electrodes is discharged while the charge in electrolyte remains mostly unchanged. The charge from electrolyte is redistributed by diffusion to the electrodes, until the charge on electrodes form the electric field which acts against the charge concentration gradient. Supercapacitor capacitance value depends on the voltage supercapacitor terminals; with increasing voltage total capacitance increases.
