A combined optical and scanning electron microscope study of the PbSO4/PbO2 electrode has revealed changes in the PbSO4 crystallography and the tendency of PbO2 to form a network during life cycle tests. It was found that during cycling a definite coralloid structure developed. The mode of deposition and crystal form of the PbSO4 crystals changed with increasing cycle life.

Kombinierte optische und rasterelektronenmikroskopische Untersuchungen der PbSO4/PbO2‐Elektrode zeigen kristallographische Änderungen des PbSO4 und eine Tendenz zur Ausbildung eines Netzwerkes bei PbO2.
