What are batteries & how do they work?

Batteries are stores of chemical energy that can be converted to electrical energy and used as a power source. In this article you can learn about: This resource is suitable for energy and sustainability topics for primary school learners. In this video, learn about different types of batteries and how they work.

How does a battery produce electricity?

“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).

What is a battery used for?

Batteries can be used to power portable devices. They let devices use electricity without the need to be plugged into main electricity sources, such as wall sockets. Mobile phones, tablets, the TV remote and torches all use batteries. Some batteries are rechargeable so they can be used again and again.

How do batteries store energy?

Batteries are used to store chemical energy. Placing a battery in a circuit allows this chemical energy to generate electricity which can power device like mobile phones, TV remotes and even cars. Generally, batteries only store small amounts of energy. More and more mobile devices like tablets, phones and laptops use rechargeable batteries.

How do rechargeable batteries work?

Rechargeable batteries (like the kind in your cellphone or in your car) are designed so that electrical energy from an outside source (the charger that you plug into the wall or the dynamo in your car) can be applied to the chemical system, and reverse its operation, restoring the battery’s charge.

Why do we need batteries?

Batteries store energy which means we can reduce waste of energy. This can help us to reduce the amount of non-renewable energy we use and therefore helps the environment. Many batteries are easy to remove and replace or recharge. Many batteries are small and portable, so they can provide electricity for mobile devices and vehicles.
