Super-capacitor is now widely used in the field of industry and daily life. With a view to improve the availability factor of Super- Capacitor, we studied the interrelationship among Super-Capacitor energy storage capacity, charging current and leakage current through a large number of experimental data analysis. Based on those experiments we draw the conclusion that super capacitor energy storage capacity tends to be stable after cycle usage; with medium-sized charging current it reaches the maximum storage capacity, while quick charge with high current will reduce its energy storage capacity.
