Batteries

Batteries are used everyday by people in many different ways, such as portable devices, automobiles, boats and more. Batteries were discovered before mechanical generators and turbines to create a steady stream of electricity. With the discovery of batteries people began to understand the importance of having a source of electricity.

The first Batteries

The first batteries were created by Alessandro Volta in 1798. Alessandro Volta invented the first true battery, which came to be known as the voltaic pile. The voltaic pile consisted of pairs of copper and zinc discs piled on top of each other, separated by a layer of cloth or cardboard soaked in brine.

Facts

Batteries come in many shapes and sizes. Some are as small as a button and others can be as big as a brick. All batteries turn chemical energy into electrical energy. This energy is used to power clocks, computers, power tools and more. Energy cannot be created or destroyed, but it can be saved in various forms, one way to store it is the form of chemical energy in a battery. When connected in a circuit, energy that is stored in the battery is released to produce electricity.

Battery Parts


Batteries have three parts, an anode, cathode and the electrolyte. The cathode and the anode are the negative and positive side to a battery, which are hooked onto an electrical circuit. The chemical reactions in the battery causes a buildup of electrons at the anode.

What is a Battery?

A battery is a device consisting of two or more electrochemical cells that convert stored chemical energy into a electrical energy. Each cell contains a positive terminal (cathode) and a negative terminal (anode). Electrolytes allow ions to move between the electrodes and terminals. It allows a current flow out of the battery to work. The term battery actually means a device with multiple cells, single cells are also popularly called batteries.
