Several preparations of PbO2 including positive active material from lead antimony and lead calcium cells were examined by electron microscopy. The morphology of the particles is believed to have a bearing on positive paste retention and plate performance in the lead acid cell. The anodic coating of PbO2 formed on pure lead sheet in H2SO4 was found to be prismatic when first formed, but lost its prismatic character upon prolong anodization and upon cycling. Author
