The construction of a lead acid battery cell is as shown in Fig. 1. It consists of the following parts : Anode or positive terminal (or plate). Cathode or negative terminal (or plate). Electrolyte. Separators. Anode or positive terminal (or plate): The positive plates are also called as anode. The material used for it is lead peroxide (PbO 2).
The plate through which the current leaves the cell to the external circuit is called the positive plate and the plate from which the current enter the cell is known as the negative plate. Type of Batteries: An electric battery consists of a number of electrochemical cells, connected either in series or parallel.
The electrolyte is then free to enter all the tiny holes in the sponge, thereby increasing the effective capacity of the battery. The negative and positive lead battery plates conduct the energy during charging and discharging. This pasted plate design is the generally accepted benchmark for lead battery plates.
A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid. Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte.
Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte. The water loss increases the maintenance requirements of the battery since the water must periodically be checked and replaced.
5.2.1 Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.

Aging mechanisms and service life of lead–acid batteries
In flooded lead–acid batteries, corrosion at the negative plates is never hardly a problem. During float service, the grid is cathodically protected, the electrode potential being maintained at about 50–100 mV below the reversible Pb/PbSO 4 potential. Only during discharge, the potential of the negative plates is forced temporarily to values positive to the reversible …
