How does a lead acid battery work?

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.

What is the working principle of a lead-acid 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:

What is the electrolyte in a lead-acid battery?

It is important to note that the electrolyte in a lead-acid battery is sulfuric acid (H2SO4), which is a highly corrosive and dangerous substance. It is important to handle lead-acid batteries with care and to dispose of them properly. In addition, lead-acid batteries are not very efficient and have a limited lifespan.

What are the components of a lead-acid battery?

A lead-acid battery is made up of several components that work together to produce electrical energy. These components include: The positive and negative plates are made of lead and lead dioxide, respectively. They are immersed in an electrolyte solution made of sulfuric acid and water.

What are lead acid batteries used for?

Lead batteries are used across a wide range of industries and applications from transportation to communication networks. When people think about lead acid batteries, they usually think about a car battery. These are starting batteries. They deliver a short burst of high power to start the engine. There are also deep cycle batteries.

How does a lead-acid battery store energy?

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.
