Impedance spectroscopy is a powerful tool to study the frequency behavior of supercapacitors, but it comes with pricy hardware and postprocessing routines. Here we present a non-impedance method to extract the fractional-order model parameters (R s , C α , α) of a supercapacitor-assumed to be equiva...
