✦ Synopsis

The cathodic behaviors of PbO (red and yellow), Pb,Ol. Pb203 and PbOr (a and 8) in lithium cells were presented. A single platectu at 1.4-1.5 V was observed over the wide range in discharge curves at 0.1 mA. cm-' for PbO (red), Pb304 and PbZ03 cathodes, and two plateaus were observed for PbO (yellow) cathode. The both types of PbO, showed the complicated behaviors in discharge curves. For a low current density discharge to ZV end-voltage, the cell with a-PbO, showed 95-100% of utilization based on one electron transfer per molecule.

The structural changes of these lead oxides during discharge were examined, and the final reduction product was proved to be lead metal. The cell reaction of these lead oxides were also examined from X-ray and electrochemical data.

The performance of 1.5 V lithium cell system with PbO (red), Pb*O, and Pbs04 cathodes, and 3 V lithium cell system with a-PbOx cathode were demonstrated and discussed.
