Electrochemical Impedance analysis of L-MCH crochet structure. a Complex plane plot (Nyquist plot) of the L-MCH crochet structure electrode impedance(dots), before (black line) and after (red line) cycles with fitted data (line). Inset is the equivalent circuit calculated from the fitted data showing series resistance, charge transfer resistance, and Warburg resistance. b Frequency dependent real capacitance and imaginary parts of L-MCH electrode’s specific capacitance. c Complex power analysis for L-MCH electrode in 4 M KOH
