Original Abstract

Supercapacitor (SC) parameters dependence on charging time is analyzed for Nesscap 2.7V / 10F. Charging was performed using constant current in the range from 0.5 A to 5 A. Reciprocal capacitance was calculated. It linearly decreases with applied charge. During SC charging, the effective distance of charges on electrode-electrolyte interface decreases, due to the charge distribution being altered by mobile ions inside electric field. Ions are at first moving by drift, and then by diffusion processes. Effective thickness of electrolyte negative charge is determined from reciprocal capacitance. The effective thickness varies between 2.6 nm and 2.1 nm.
