A novel flow battery: a lead acid battery based on an electrolyte with soluble lead(II): Part VII. Further studies of the lead dioxide positive electrode

Record type: Article

Extensive cycling of the soluble lead flow battery has revealed unexpected problems with the reduction of lead dioxide at the positive electrode during discharge. This has led to a more detailed study of the PbO2/Pb2+ couple in methanesulfonic acid. The variation of the phase composition (XRD) and deposit structure (SEM) have been defined as a function of current density, Pb2+ andH+ concentrations, deposition charge and temperature aswell as the consequences of charge cycling. Pure-PbO2, pure-PbO2 and their mixtures can be deposited from methanesulfonic acid media. The -phase deposits as a more compact, smoother layer, which iswell suited to charge cycling. While the anodic deposition of thick layers of PbO2 is straightforward, their reduction is not; the complexities are explained by an increase in pH within the pores of the deposit. The results suggest that operating the battery at lead(II) concentrations <0.3M and elevated temperatures should be avoided.
