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.
Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.
The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost. The various parts of the lead acid battery are shown below. The container and the plates are the main part of the lead acid battery.
The container stores chemical energy which is converted into electrical energy by the help of the plates. 1. Container – The container of the lead acid battery is made of glass, lead lined wood, ebonite, the hard rubber of bituminous compound, ceramic materials or moulded plastics and are seated at the top to avoid the discharge of electrolyte.
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 -
Batteries use 85% of the lead produced worldwide and recycled lead represents 60% of total lead production. Lead–acid batteries are easily broken so that lead-containing components may be separated from plastic containers and acid, all of which can be recovered.
