What is a battery used for?

This battery has its application in giving power to the electric motors of electric vehicles like battery electric vehicles (BEV) or hybrid electric vehicles (HEV). The batteries of electric vehicles are usually rechargeable (secondary) batteries, and typically lithium-ion batteries are used.

What are the major uses of batteries in our day-to-day life?

Here are some major uses of batteries in our day-to-day life. Batteries are used in various things that we use in our house. Batteries are used to power things like remote controls, torches, wall clocks, flashlights, hearing aids, weight scales, etc.

What are rechargeable batteries used for?

They can be used in two applications: In the first application, secondary batteries supply and store energy. Take UPS, a battery backup, for example. It provides reserve power when your regular power source fails. This device is often used for computers. As for the second application, rechargeable batteries also work for portable electronics like:

What are lithium ion batteries used for?

Lithium-ion batteries are used in heavy electrical current usage devices such as remote car fobs. These are widely used batteries that are commonly found in laptops, mobile phones, cameras, etc. Lithium-ion batteries typically have a higher energy density, little or no memory effect, and lower self-discharge than other battery types.

How do batteries work?

In summary, batteries operate based on redox electrochemical reactions that convert chemical energy into electrical energy. The charging process stores energy by reversing these reactions, while discharging provides energy. Regarding batteries, several main performance factors need to be considered. Let’s take a look at each of these in order.

Why do we need batteries?

Batteries solve this problem by reducing the storage capacity very little and eliminating the need to carry fuel. Batteries are one of the most convenient ways to store power.
