Název v původním jazyce

Charge Redistribution and Restoring voltage of Supercapacitors

Popis výsledku v původním jazyce

Electric charge in supercapacitor is stored on electrodes as well as inside its electrolyte. Charges on electrodes create Helmholtz double layer which is formed immediately with time constant in the order of seconds, while the storage of charge in electrolyte takes time in the order of hundreds of seconds. When the charged supercapacitor is briefly short-circuited, the charge on electrodes is discharged, however the charge in electrolyte remains mostly unchanged. The charge stored in electrolyte is redistributed by diffusion to the electrodes, until the charge on electrodes form electric field which acts against the charge concentration gradient and equilibrium state occursfor charge-carrier exchange at electrode/electrolyte interface. Supercapacitor capacitance value depends on the voltage of its terminals; with increasing voltage total capacitance increases
