Battery Application & Technology All lead-acid batteries operate on the same fundamental reactions. As the battery discharges, the active materials in the electrodes (lead dioxide in the positive electrode and sponge lead in the negative electrode) react with sulfuric acid in the electrolyte to form lead sulfate and water.
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).
Current collectors in lead acid batteries are made of lead, leading to the low-energy density. In addition, lead is prone to corrosion when exposed to the sulfuric acid electrolyte. SLI applications make use of flat-plate grid designs as the current collectors, whereas more advanced batteries use tubular designs.
There are huge chemical process is involved in Lead Acid battery’s charging and discharging condition. The diluted sulfuric acid H 2 SO 4 molecules break into two parts when the acid dissolves. It will create positive ions 2H+ and negative ions SO 4 -. As we told before, two electrodes are connected as plates, Anode and Cathode.
Construction, Working, Connection Diagram, Charging & Chemical Reaction Figure 1: Lead Acid Battery. The battery cells in which the chemical action taking place is reversible are known as the lead acid battery cells. So it is possible to recharge a lead acid battery cell if it is in the discharged state.
In a sealed lead acid (SLA) battery, the hydrogen does not escape into the atmosphere but rather moves or migrates to the other electrode where it recombines (possibly assisted by a catalytic conversion process) to form water.
