Abstract:
Current trends in supercapacitor technology (principially in lowering series discharge resistance) have promoted the devices into roles parallel to, or replacing traditional batteries. In cases where power consumption is low, supercapacitors are an attractive alternative, completely eliminating batteries and further offering higher surge currents. This opens the path towards powering mobile switching circuits, or with high-consumption for short periods.
One of the methods used to determine the after mentioned parameters is Electrochemical Impedance Spectroscopy (EIS).
