The components in Lead-Acid battery includes; stacked cells, immersed in a dilute solution of sulfuric acid (H 2 SO 4), as an electrolyte, as the positive electrode in each cells comprises of lead dioxide (PbO2), and the negative electrode is made up of a sponge lead.
One of the singular advantages of lead acid batteries is that they are the most commonly used form of battery for most rechargeable battery applications (for example, in starting car engines), and therefore have a well-established established, mature technology base.
Lead–acid batteries consist of a metallic lead (Pb) negative electrode, a lead dioxide (PbO 2) positive electrode, and a sulfuric acid electrolyte. The overall cell reaction is The voltage of lead–acid cells on open circuit is approximately 2 V; a standard 12-V (SLI) battery therefore consists of six individual cells connected in series.
5.2.1 Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.
[...] ... The active components involved in lead-acid storage battery are negative electrode made of spongy lead (Pb), positive electrode made of lead dioxide (PbO 2 ), electrolyte solution of sulphuric acid (H 2 SO 4 ) and Separator which is used to prevent ionic flow between electrodes and increasing of internal resistance in a cell.
Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte. The water loss increases the maintenance requirements of the battery since the water must periodically be checked and replaced.

The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…
