How to Measure and Calculate Equivalent Series Resistance of Electric Double-Layer Capacitors.

Electric double-layer capacitors (EDLCs) are energy storage devices that have attracted attention from the scientific community due to their high specific power storage capabilities. The standard method for determining the maximum power () of these devices uses the relation = /4, where stands for the cell voltage and for the equivalent series resistance. Despite the relevance of , one can observe a lack of consensus in the literature regarding the determination of this parameter from the galvanostatic charge-discharge findings.
