摘要：

The thermal degradation of alpha and beta PbO2 and its relationship to capacity loss was studied using galvanostatic discharge and voltamperometry. The results clearly demonstrate the dramatic effect of the thermal treatment on the capacity of the PAM. The variation of proton diffusion with temperature was determined for both alpha- and beta-PbO2. The two forms of PbO2 exhibit different behaviour with regard to water loss.
