Double layer charging current
Webcharge current or higher voltage than specified. Self discharge and leakage current Self discharge and leakage current are essentially the same thing measured in different ways, due to the supercapacitor construc-tion there is a high impedance internal current path from the anode to the cathode. This means that in order to maintain the charge on Web1.2.4 Double-Layer Capacitance and Charging Current in Electrochemical Measurements Let us derive the governing equation of the current transient, i, with time, t, when applying a potential step of magnitude E 1) This derivation is started from the general equation for the charge, q, on a
