Lead acid battery cell consists of spongy lead as the negative active material, lead dioxide as the positive active material, immersed in diluted sulfuric acid electrolyte, with lead as the current collector:
Due to the production of hydrogen at the positive electrode, lead acid batteries suffer from water loss during overcharge. To deal with this problem, distilled water may be added to the battery as is typically done for flooded lead acid batteries. Also, maintenance-free versions are available to deal with this problem whereby inserting a valve keeps the gasses within the battery and
Also, the lead sulfate on the positive electrodes recombines with water to regenerate lead peroxide on the positive plates and sulfuric acid in the electrolyte. The final result of charging the cell is that the electrodes are re-formed, and the electrolyte is returned to its original strength. With proper care a lead—acid battery is capable of sustaining a great many cycles of charge and

The lead-acid battery consists negative electrode (anode) of lead, lead dioxide as a positive electrode (cathode) and an electrolyte of aqueous sulfuric acid which transports the charge between the two. At the time of discharge both electrodes consume sulfuric acid from the electrolyte and are converted to lead sulphate. While recharging the
When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode. Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if

Components of a Lead-Acid Battery. A lead-acid battery is composed of several key elements that work together to enable its functionality: 1. Electrodes. Positive Plate: Made of lead dioxide (PbO2), this electrode is essential for the chemical reactions that occur during both charging and discharging.
The battery consists of two electrodes, a positive electrode (known as the cathode) and a negative electrode (known as the anode), immersed in an electrolyte solution of sulfuric acid and water. When the battery is charged, a chemical reaction occurs between the lead and the sulfuric acid, which produces lead sulfate and water.

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 aging of lead acid batteries is mainly caused by internal corrosion of the lead structure of the electrodes, the formation of fine short circuits, and by sulfating of the lead. Lead and lead dioxide, the active materials on the battery's plates, react with sulfuric acid in the electrolyte to form lead sulfate.
Wide differences in cycle performance may be experienced with two types of deep cycle batteries and therefore the cycle life and DOD of various deep-cycle batteries should be compared. A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid.
