Corresponding Nyquist plots (a), Bode plots (b) and Tafel curves (c) of the symmetrical dummy cell towards aqueous polysulfide electrolyte with a recipe of 1 M sulfur, 1 M Na2S 9H2O and 0.1 M NaOH in deionized water.
The frequency range was set from 100 mHz to 1 MHz and the amplitude of the alternating current was set to 10 mV in the impedance measurements. Tafel measurements were performed with a scanning rate of 10 mV s−1.
