Abstract

By measuring the thickness of the negative plates with and without an expander, during cycling, it was established that the active mass volume pulsates, expanding during discharge and shrinking during charge. This phenomenon is due to the mechanical stress in the lead skeleton structure caused by the PbSO4 crystals. At each pulsation of the plate, slight changes in the structural parameters of the active mass are observed. These changes accumulate during cycling causing expansion or shrinking of the active mass. As a result of this the capacity of the plate decreases. These changes in the plate structure depend strongly on the expander.
