A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
The working principle of a lead-acid battery is based on the chemical reaction between lead and sulfuric acid. During the discharge process, the lead and lead oxide plates in the battery react with the sulfuric acid electrolyte to produce lead sulfate and water. The chemical reaction can be represented as follows:
Thus, fast charging of a lead–acid cell can be achieved without a loss of cycle-life, despite the fact that higher currents are forced into the cell. 1. Introduction The fast charging of a lead–acid battery, or indeed other secondary rechargeable batteries, is a key technology for electric vehicles.
A lead-acid battery stores energy through a chemical reaction that takes place between lead and lead dioxide plates and sulfuric acid electrolyte. The energy is stored in the form of potential difference or voltage between the two electrodes.
In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge. The dependence of the battery on the battery state of charge is shown in the figure below.
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.

In lead-acid batteries, chemical reactions occur between lead dioxide, sponge lead, and sulfuric acid. These reactions produce lead sulfate and electricity. At temperatures below freezing, the efficiency of these reactions decreases. A study by M.M. Aamir et al. (2019) notes that reaction rates can drop significantly, leading to lower voltage outputs from the battery.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
The lead alloy is fashioned into a grid to hold the active material mechanically, and to conduct electricity between this material and the terminals of the battery. Calcium, silver, and cobalt are among many materials that can be used to make the lead stiffer. Lead oxide is made into a dough-like material so it can be attached to the grid. The lead-acid battery uses …

While concentrated sulfuric acid does not conduct electricity, diluted sulfuric acid does. Sulfuric acid breaks down into hydrogen and sulfate ions when mixed with water. Numerous ions with the electric charge needed to conduct electricity are produced during the separation process. Because concentrated sulfuric acid contains so few ions, it conducts electricity poorly.
