Typical CV plots of Pt obtained in LiCl melts containing 1, 2 and3 wt % Li2O are shown in Fig. 3a, 3b and 3c respectively. Three anodicwaves 1, 2 and 3 and two cathodic waves 4 and 5 are clearly visiblein the plots. It has been confirmed in previous studies [7–9] thatthe anodic waves 1, 2 and 3 correspond to the following reactionsrespectively.
