Abstract
⺠The discharge product of the Pb/PbSO4 interface can be described as a continuous metal/film interface. ⺠The continuous films at this interface have ionic resistivity 102-103 times lower than passivating films. ⺠These grown films on discharging can suffer partial disruption giving partial disrupted films which recrystallize giving porous external films. ⺠The Pb/PbSO4 interface gives under oxidation an exchange current density i0 of 44 mA cmâ2 and an αa of 0.46. Under the reduction of aged films, i0 is 2.48 mA cmâ2 and αc 0.95 (symmetric barrier).
