Lead Storage Battery
What is Lead Storage Battery?
A lead-acid (lead storage) battery is a rechargeable electrochemical cell in which the anode is lead (Pb), the cathode is lead(IV) oxide (PbO₂), and the electrolyte is sulfuric acid solution. During discharge, both electrodes are converted to lead(II) sulfate while releasing electrical energy; the process is reversed during charging. Lead-acid batteries are widely used as automotive batteries due to their low cost, reliability, and ability to supply high surge currents.
