Figure 4. ZAB using Pt/C-RuO2 and NiCo2O4@MnO2/CNTs-Ni foam. (A) OCV curves. (B) Polarization curves and corresponding power density plots. (C) Total ASR curves. (d) Different rate discharge cycling curves at different current densities (5-30 mA cm-2). (E) Charge and discharge polarization curves. (F) Charge-discharge cycles at 5 mA cm-2 (insert: a small bulb powered by a ZAB in series).
