The battery that uses lead and lead peroxide for the conversion of the chemical energy into electrical energy is called a lead-acid battery.
This battery is used in small portable equipment such as emergency lights. These are also used in Cars.
Construction:
The lead-acid battery consists of a container, plates, active material, separators, and battery terminals.
Container: The material used for the containers is made of material resistant to sulfuric acid.
Plates: There are positive and negative plates used in the battery. These are made up of an alloy of lead and antimony.
Active material: The material in a cell that takes active participation in a chemical reaction during charging or discharging is called the active material of the cell. It consists of Lead peroxide, sponge lead, and H2SO4.
Separators: These are the thin sheets of non-conducting materials that are placed between the positive and negative to insulate them from each other.
Terminals: There are two terminals in the battery, one positive, and the other one negative.
