Mg-ZnO/Nickel redox battery 성능 |

This study focused on improving the cell efficiency of Zinc-Nickel redox battery. The cycle life of zinc anodic material in KOH alkaline electrolyte was enhanced by small amount of Mg insertion into ZnO framework through a typical hydrothermal method. The as-prepared ZnO and MgxZn1-xO (x=0.001, 0.0025, and 0.005) anodic materials before and after charging/discharging test were characterized by XRD, SEM, and EDX to investigate the effect of inserted Mg ions on the zinc dendrite growth. CV and EIS were utilized to examine the electrochemical performances of Mg-inserted ZnO as anodic material. The Mg-inserted ZnO-Ni membrane free redox batteries possess higher discharge voltage, higher cycle stability, lower corrosion current, and smaller charge-transfer resistance in comparison with bare ZnO. In addition, the redox cell efficiency was 85% in the ZnO anodic material inserted Mg of 0.0025 mol. even after 100 cycles. |
