In an automotive lead acid battery the negative plate when the battery is charged consists of?

In a charged lead-acid battery, the negative plate consists primarily of spongy lead (Pb). During the charging process, lead sulfate (PbSO4) on the negative plate is converted back into lead and sulfate ions. This transformation allows the battery to store electrical energy effectively. The spongy structure of the lead enhances the surface area, facilitating better charge and discharge cycles.
