Abstract

Various anodic and cathodic processes that occur in a valve regulated lead-acid battery (VRLA) under float conditions were separated and measured accurately from in situ measurements of volumetric, voltammetric and gas analysis. All of these processes including oxygen evolution, grid corrosion of the positive, hydrogen evolution and oxygen recombination were monitored as the battery changed from a flooded electrolyte state to a starved condition. Grid corrosion of the positive electrode in the starved electrolyte condition was found to be three times greater than in the flooded state
