The equivalent series resistance (ESR) of the electrode can be obtained from the x intercept of the Nyquist plot. The ESR of NiMoO4 and CoMoO4 electrode are 3.48 Ω and 3.59 Ω, respectively. The diameter of semi-circle corresponds to the charge transfer resistance caused by Faradic reactions in parallel with the double-layer capacitance at the electrode electrolyte interface. According to the enlarged plots, the size of the semicircle, which equals the charge transfer resistance Rct, is smaller for the NiMoO4 electrode (0.8 Ω) compared to that of the CoMoO4 electrode (1.2 Ω), indicating that the binder-free electrode design could greatly improve the conductivity, thus leading to enhanced electrochemical properties..
