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. Overall battery capacity is increased by adding additional pairs of plates. A pure lead grid structure would not be able to support the above framework vertically.
In the charged state, the positive active-material of the lead–acid battery is highly porous lead dioxide (PbO 2). During discharge, this material is partly reduced to lead sulfate. In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead.
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).
In this condition, the positive plates are brown in color, and the negative plates are gray. When the battery is discharging (i.e., supplying a current), atoms from the spongy lead on the negative plates combine with sulfate molecules to form lead sulfate and hydrogen.
In a lead-acid cell the active materials are lead dioxide (PbO2) in the positive plate, sponge lead (Pb) in the negative plate, and a solution of sulfuric acid (H2SO4) in water as the electrolyte. The chemical reaction during discharge and recharge is normally written:
In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead. Whereas this so-called ‘Planté plate’ is still in demand today for certain battery types, flat and tubular geometries have become the two major designs of positive electrode.
