Figure 6. Current I is plotted vs time t for two different charging voltages (charging time 20 s, respectively). The upper, left area (bright red area) is the total charge for the charging reaction (0.84 A s), while the lower right area is the charge for the discharge reaction (0.82 A s). In addition, the latter area is divided into the charge which results in the rection AgO → Ag2O (bright, lower area: 0.2 A s) and the charge from reaction Ag2O → Ag (dark, lower area: 0.62 A s)
