This paper aims to report information on electrical and microstructural characteristics of electrodes applied at devices that store energy, specifically supercapacitors made of activated carbon electrodes.

The studied electrical parameters were the equivalent series resistance obtained by the method of the instantaneous value of the voltage drop ESR Instwhere the acronym ESR has the meaning Equivalent Series Resistance, the equivalent parallel resistance EPR Dep obtained by the method trrmoionico dependent value, where the acronym EPR has the meaning Equivalent Parallel Efeio, and the capacitance C DC obtained by the method of direct current.
