Figure 3

Charge/discharge curves of (a) Mg–Fe–O and (b) Mg–Ni–O with a cut-off potential of − 1.155 ~ 0.845 V vs. Ag/Ag+ (1.445 ~ 3.445 V vs. Mg/Mg2+). (c) Charge/discharge curves of Mg–Fe–O with a cut-off potential of − 1.6 ~ 1.1 V vs. Ag/Ag+ (1.0 ~ 3.7 V vs. Mg/Mg2+) are also presented. All the measurements were carried out at 90 °C with the current density of 5 mA g–1.
