Lead–Acid Batteries
For example, the grid in lead–acid batteries is made of solid lead and the active mass, a sponged lead for the negative electrode is pressed into the grid. The grid itself is maybe only partially exposed to electrolyte and it mainly serves as the mechanical support for the active mass and as a current collector. Over time, however, the lead in the grid slowly gets

8.3: Electrochemistry
This reaction regenerates the lead, lead (IV) oxide, and sulfuric acid needed for the battery to function properly. Theoretically, a lead storage battery should last forever. In practice, the recharging is not (100%) efficient because some of the lead (II) sulfate falls from the electrodes and collects on the bottom of the cells.

Basics of lead–acid battery modelling and simulation
The electrode reactions in the lead–acid system are true electrochemical conversions with significantly nonlinear Butler-Volmer kinetics, which differentiates them from intercalation electrodes and capacitive or pseudo-capacitive electrodes. As a consequence, charge transfer in lead–acid batteries cannot be modelled as a linear resistance

Lead–acid battery fundamentals
It can be seen that the HSO 4 − ions migrate to the negative electrode and react with the lead to produce PbSO 4 and H + ions. This reaction releases two electrons and thereby gives rise to an excess of negative charge on the electrode that is relieved by a flow of electrons through the external circuit to the positive electrode.
