A passivation layer containing Pt δ –OH ads, Pt (II) species (Pt (II) (OH) 2 and Pt (II) O), and Pt (IV) O 2 formed on the Pt 0 substrate (Fig. 14 a). Moreover, Martelli et al. proposed two different mechanisms for the passivation of Ti/IrO 2-Ta 2 O 5 in an acidic electrolyte during OER [93]. They suggested that an additional layer (A ...

Anode optimization strategies for zinc–air batteries

The insulating ZnO passivation film inhibits the discharge process, thus reducing both the zinc electrode utilization and the battery capacity; this is one of the important reasons for the large difference between the theoretical energy density of the zinc–air battery (1,086 Wh kg –1) and its actual energy density (200–300 Wh kg –1) [58 ...

The passivation mechanism of negative plates has been investigated by means of linear sweep voltammetry and scanning electron microscopy. It is found that the reduction peak of PbSO 4 is split into two peaks on a seriously passivated negative plate. This is attributed to the reduction of PbSO 4 crystals of different sizes.
