Abstract
A computer simulation of the structure and modes of functioning of active layers (activated carbon, with aqueous electrolyte)
in double-layer capacitors (DLCs) was performed. Charging of the DLCs was studied. The main characteristics of the DLCs
(charging time, specific capacity, and stored energy) were calculated. The central problem of calculation of the DLCs with a real, nonmonoporous structure was formulated. The DLCs with the ideal structure were suggested and studied. Polarization of ideal active layers includes a sequence of two charging processes: the first one is galvanostatic and the second one is potentiostatic. In ideal structure with thickness of 1 cm, the specific capacity C=2450 F/сm2 and stored energy W=1200 J/сm2 were reached.
