In full charge cycle the charge voltage remains constant and the current gradually decreased with the increase of battery charge level. Discharging of a lead acid battery is again involved with chemical reactions. The sulfuric acid is in the diluted form with typically 3:1 ratio with water and sulfuric acid.
The electrical energy is stored in the form of chemical form, when the charging current is passed. lead acid battery cells are capable of producing a large amount of energy. 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).
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.
If we break the name Lead Acid battery we will get Lead, Acid, and Battery. Lead is a chemical element (symbol is Pb and the atomic number is 82). It is a soft and malleable element. We know what Acid is; it can donate a proton or accept an electron pair when it is reacting.
Lead acid batteries store energy by the reversible chemical reaction shown below. The overall chemical reaction is: P b O 2 + P b + 2 H 2 S O 4 ⇔ c h a r g e d i s c h a r g e 2 P b S O 4 + 2 H 2 O At the negative terminal the charge and discharge reactions are: P b + S O 4 2 - ⇔ c h a r g e d i s c h a r g e P b S O 4 + 2 e -
Following are some of the important applications of lead – acid batteries : As standby units in the distribution network. In the Uninterrupted Power Supplies (UPS). In the telephone system. In the railway signaling. In the battery operated vehicles. In the automobiles for starting and lighting.
