“…Further, the relative utilization of PAM compared to that of the negative active mass (NAM) is lower. At low discharge rate, the PAM utilization is only about 50% for automotive lead-acid batteries and it becomes smaller with the increase of the discharge rate [15][16][17]. During the cycling of VRLA batteries, the swelling and shedding of the PAM leads to premature capacity loss (PCL-2) [18].…”

In situ electrochemical scan to study the behavior of the asymmetric (single-side) pasted positive plate as used in automotive lead-acid batteries Abstract The performance of a asymmetric (single-side) pasted positive plate was studied by measuring the current density and potential distributions on both sides of the plate. It was found that the current densities on both sides are almost the same during the early discharge at the 3 C discharge rate. As the discharge proceeds, the current decreases gradually on the non-pasted side and increases on the pasted side. Since more active mass exists on the pasted side, the matrix resistance is higher, causing the polarization to increase by 55-90 mV at the 3 C discharge rate. On the non-pasted side, the active mass undergoes a deeper depth of discharge (DOD). This leads to the shedding of active mass, which shortens the battery life. Since the positive grid on the non-pasted side is exposed, its corrosion rate is faster.

Combined voltammetry and potentiostatic current transient techniques have been employed to study the electroreduction of anodically formed lead oxide layers, which build up beneath the initially grown PbSO4 crystal, on polycrystalline lead electrodes in concentrated sulphuric acid solution in the 0 to 50 ° C temperature range. Current transient analysis of the PbO electroreduction performed by using parametric identification procedures and nonlinear fit routines has demonstrated that kinetic data can be mainly interpreted in terms of a progressive nucleation and three-dimensional growth mechanism under charge transfer control, whereas in the initial short time range a process under H + ion diffusion control has been detected. The phenomenological explanation of the temperature effect on electrode processes is based on the Arrhenius behaviour of kinetic operational parameters.
