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.
But in a battery, electricity is produced in a completely different way. A battery is made up of a series of cells stacked together. These contain chemicals that react and produce electricity when they are connected in a circuit. The single unit of a battery. It is made up of two different materials separated by a reactive chemical.
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.
Batteries convert chemical energy directly to electrical energy. In many cases, the electrical energy released is the difference in the cohesive [ 17 ] or bond energies of the metals, oxides, or molecules undergoing the electrochemical reaction.
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.
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.
