It changes the stored energy in the chemicals into electrical energy.

Something called "cells" is present in it.

These cells consist of electrodes, electrolytes, and a separator inside them.

Electrodes are objects created using different metals or combinations of metals.

The electrolyte is a liquid that assists ions in transferring between the electrodes.

When you connect a shower to something like a light bulb or a toy, the shower starts a process where the things inside it mix or react with each other.

→ This process makes tiny things called electrons move from the shower's negative side to the battery's positive side.

→ This tiny burst of electrons is what gives energy to the device that keeps the shower working steadily.

When electrons move in a specific way, they create a flow called an electrical current.

This current is used to make electronic devices and other electrical systems work.

→ Batteries can be found in various colors and sizes.

These things are very helpful.

They make phones and computers work well and perform their tasks effectively.

They can also be used for good things like making electric cars function and obtaining energy from the sun or wind.

 Types of Batteries

There are different kinds of batteries.

Each type has its own special features and purposes.

➲ Alkaline Batteries

These batteries are used a lot in toys, remote controls, and small handheld lights. 

These things are not costly and can be kept for a long time without getting spoiled.

➲ Lithium-ion Batteries

These are batteries that you can use many times.

They are often found in small things like phones, laptops, and cameras.

These things are famous because they can store a large amount of energy in a small space and can continue functioning for a long time before requiring another charge.

➲ Lead-acid Batteries

→ These things make cars, boats, and motorcycles move.

→ They are not costly and can generate a lot of power considering their weight.

➲ Nickel-cadmium Batteries

Rechargeable batteries are batteries you can use, charge, and use again.

They are commonly used in things like phones without wires, tools that run on electricity, and small portable gadgets.

They stay a long time and can carry strong electric currents.

➲ Nickel-metal Hydride Batteries

These batteries can be charged again and are used in things like cameras and small electronic devices.

Lithium-ion batteries can store increasingly energy per weight than nickel-cadmium batteries, but they have a shorter lifespan.

➲ Zinc-carbon Batteries

These batteries are inexpensive and can be disposed of after using them.

They are often used in simple devices like clocks, remote controls, and flashlights that don't require much power.

➲ Lithium Polymer Batteries

These are small batteries that can be charged many times.

They are often used in things like cell phones and toys that you control from far away.

 Application of Batteries

Batteries are used in lots of places.

Application of Batteries

➲ Consumer electronics

People use batteries in small things they can carry, like phones, computers, tablets, and cameras.

➲ Automotive industry

Batteries make cars work by providing power to the electrical parts like the motor that starts the car, the lights, and other extra things.

➲ Renewable energy storage

Batteries can store power from solar panels and wind turbines.

We can use this stored power when renewable energy is not being produced.

➲ Medical devices

Batteries are used in medical tools for important purposes like helping hearts, aiding hearing, and testing sugar levels in horses.

➲ Military and defense

The military uses batteries for radios, GPS devices, and night vision equipment.

➲ Aviation and aerospace

Batteries make airplane communication and navigation systems work.

They are also used in satellites and space probes.

➲ Emergency backup power

Batteries are things we use to save energy when the normal power stops or during emergencies.

➲ Electric vehicles

Electric cars use batteries to work.

The batteries give power to the car's electric motor and other electrical parts.

➲ Marine industry

Batteries make boats and ships work by providing power for things like navigation systems and lights.

➲ Industrial applications

Batteries are used in many industries.

They are important for different things like keeping data centers powered in case of a problem, helping move heavy objects using special equipment and giving light during emergencies.
