Lead–acid battery principles. The overall discharge reaction in a lead–acid battery is: (1)PbO2+Pb+2H2SO4→2PbSO4+2H2O. The nominal cell voltage is relatively high at 2.05 V. The positive active material is highly porous lead dioxide and the negative active material is finely divided lead.
The VRLA battery is designed to operate by means of an ''internal oxygen cycle'' (or ''oxygen-recombination cycle''). Within each cell of the battery, oxygen evolved during the latter stages of charging and during overcharging of the positive electrode, i.e., (13.4) H 2 O → 2 H + + ½ O 2 ↑ + 2 e − oxygen transfers through a gas space to the …
Conversely, a lead acid battery has a shorter lifetime, it is very sensitive to the depth of discharge but with a high energy density. In addition, lead acid battery has low power density which could escalate the rate of degradation and corrosion when high inrush current is drawn from the battery leading to quick ageing of the battery. These ...
