The thin film PbO2/PbO/Pb solid cells were produced by reactive sputtering and vacuum evaporation on glass substrates, and the discharge properties were investigated. A PbO2 layer was obtained by sputtering of the Pb target in oxygen plasma. PbO, which is an oxygen ion conductor, was deposited from β-PbO powder in a vacuum. The open-circuit voltage of the PbO2/PbO/Pb cell was in good agreement with the theoretical value based on the thermodynamic data, and the partial transformation of β-PbO to α-PbO in the electrolyte did not show any marked change in voltage. The close-circuit voltage, which could be measured by connecting with a 100 kΩ resistor, was deteriorated by doping of the Bi3+ ion to the electrolyte, PbO. On the other hand, the doping of the K+ ion inhibited the decrease in discharge voltage. Moreover, the charge-discharge cycling test revealed that the PbO2/PbO/Pb cell could be charged to behave as a storage battery and that the connection of the cells in series and in parallel supplied a higher electromotive force and a larger capacity.
