Figure 2. Performance of Zn||Zn symmetric and Zn||Cu asymmetric coin cells with/without SPr-Bpy in 0.5 M ZnCl2. (A) Long-term cycling of Zn||Zn symmetric cells with various concentrations of SPr-Bpy. (B and C) Voltage-capacity curves of Zn||Cu cells under different cycle numbers (B) with 25 mM SPr-Bpy and (C) Blank electrolytes. (D) The corresponding CE plots with respect to the cycle number of Zn||Cu cells.
