One of the most important properties of lead–acid batteries is the capacity or the amount of energy stored in a battery (Ah). This is an important property for batteries used in stationary applications, for example, in photovoltaic systems as well as for automotive applications as the main power supply.
Technical progress with battery design and the availability of new materials have enabled the realization of completely maintenance-free lead–acid battery systems [1,3]. Water losses by electrode gassing and by corrosion can be suppressed to very low rates.
The active masses of the negative and positive electrodes were electrochemically prepared on lead plates, a process still used even today. Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte.
Electrode potentials and cell voltage for a typical flooded lead–acid battery As charging proceeds, the potentials keep gradually increasing until end of charge is reached. At this point, all lead sulfate is converted to lead on the negative electrode and to lead dioxide on the positive; and the charge is complete.
Normally, as the lead–acid batteries discharge, lead sulfate crystals are formed on the plates. Then during charging, a reversed electrochemical reaction takes place to decompose lead sulfate back to lead on the negative electrode and lead oxide on the positive electrode.
Sealed lead–acid batteries are constructed differently and have hydrogen and oxygen gases recombined inside a cell. While the majority of lead–acid batteries used to be flooded type, with plates immersed in the electrolyte, there are now several different versions of lead–acid batteries.
