Electrochemical characterizations of 5 M Zn eutectic mixture | separator | Li half-cell. (a) Cyclic voltammogram profile recorded at a sweeping rate of 10 mV·s−1 showing the electrochemical window of Zn eutectic mixture; (b) electroplating/electrostripping ratio (rplating/rstripping) versus ZnCl2 concentration (cZn) of Zn eutectic mixtures at room temperature. The cut-off voltage is set to 0.9–2.3 V vs. Li+/Li and the current density is set to 0.2 mA·cm−2; (c) short-term cycling performance. The charging and discharging time is fixed to 2.5 hrs, and the current density is set to 0.2 mA·cm−2; (d) SEM image showing the typical morphology of electroplated Zn on Zn foil in a fully discharged half-cell.
