Working of Lead-Acid Battery (With Diagram) | Electricity
In this article we will discuss about the working of lead-acid battery with the help of diagram. When the sulphuric acid is dissolved, its molecules break up into hydrogen positive ions (2H+) and sulphate negative ions (SO4- -) and move freely. Now if two lead electrodes are immersed in this solution and connected to dc supply mains, the hydrogen …

A small value of factors α and γ of the negative and positive electrodes based on RVC/Pb in comparison to classic lead-acid battery plates will improve the …
Discharge and Charging of Lead-Acid Battery
When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte. The sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in Equation.
