Figure 1. Typical representation of a cyclic voltammogram of a pure Ni(OH) 2  electrode at a scan rate  of 0.1 mV·s −1  in 1 M KOH electrolyte
Figure 2. Relative capacity distribution upon the 80 electrode materials studied. The blue bars stand  for electrode materials which exhibit less than 100% of the theoretical capacity and the red bars for  those which exhibit relative capacity higher than
