Resumo
The effect of the working temperature on the capacity, internal equivalent serial
resistance (ESR), equivalent parallel resistances (EPR) of some retail available electric double layer
capacitors (EDLC) have been investigated. Standard capacities of 1.0 F at a maximum potential of
5.5 V were employed in this study. EPR values have been calculated using the self-discharge curves
at temperatures above to the nominal maximum working temperature of the supercapacitors
(~70oC). The ESR values were measured during charge using the constant current (1 mAF-1)
interrupt method with oscilloscope. Microstructural characterization of the electrode material have
been carried out using scanning electron microscopy (SEM) and chemical microanalyses employing
energy dispersive X-ray analysis (EDX).
