Self Discharge through Leakage Mechanisms

Alternatively, leakage behavior can be determined by measuring the selfdischarge voltage by (1) charging the device by applying a slow voltage ramp

Fibril conduction through separator Shunt resistances between electrodes Ohmic ]ogV versus t 

These faradic leakage measurements are also dependent upon temperature (log I vs. j) where the slope is determined by the activation energy of the mechanism. As a result faradic leakage currents can have important impacts on high temperature performance.
