3.2.2 Lead-acid battery. The lead-acid battery is the most important low-cost car battery. The negative electrodes (Pb-PbO paste in a hard lead grid) show a high hydrogen overvoltage, so that 2 V cell voltage is possible without water decomposition. A lead grid coated with lead dioxide forms the positive electrode.
The pb-acid cell is often described as having a negative electrode of finely divided elemental lead, and a positive electrode of powdered lead dioxide in an aqueous electrolyte. If this were strictly true and there were no other important species present, the cell reaction would simply involve the formation of lead dioxide from lead and oxygen:
SECONDARY BATTERIES – LEAD– ACID SYSTEMS | Positive Electrode. K.R. Bullock, in Encyclopedia of Electrochemical Power Sources, 2009.

The Planté plate is the oldest type of positive electrode for a lead–acid battery. The active-material (lead dioxide) is directly formed by an electrochemical process from cast lead plates that have numerous thin vertical grooves, strengthened by a series of horizontal cross-ribs to increase the surface-area.
The battery which uses sponge lead and lead peroxide for the conversion of the chemical energy into electrical power, such type of battery is called a lead acid battery. The container, plate, active material, separator, etc. are the main part of the lead acid battery.
Luckily, we do have batteries. Back in 150 BC in Mesopotamia, the Parthian culture used a device known as the Baghdad battery, made of copper and iron electrodes with vinegar or citric acid. Archaeologists believe these were not actually batteries but were used primarily for religious ceremonies.
When an external voltage in excess of 2.04 V per cell is applied to a lead–acid battery, the electrode reactions reverse, and (PbSO_4) is converted back to metallic lead and (PbO_2). If the battery is recharged too vigorously, however, electrolysis of water can occur:

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.
When the battery is recharged, a current (conventional direction) is made to flow into the positive electrode of each cell. This current causes the lead sulfate at the negative electrode to recombine with hydrogen ions, thus re-forming …
Lead calcium batteries are a variation of the traditional lead-acid battery. They are constructed using lead as the negative electrode (cathode), and a lead oxide compound coating the positive electrode (anode). The addition of calcium in the electrodes is what distinguishes lead calcium batteries from other types of lead-acid batteries. The ...

The electrodes are connected by wires to a battery or other source of direct current. This current source may be thought of as an "electron pump" which takes in electrons from one electrode and forces them out into the other electrode. The electrode from which electrons are removed becomes positively charged, while the electrode to which ...
