Count Alessandro Volta first discovered the battery in 1799 when he created “The Voltaic Pile” which consists of a discs of copper and zinc separated by discs of paper or cardboard soaked in salt water, and a copper wire attached to the top and bottom of the Pile.
When Volta closed the circuit, electricity flowed through the pile.
While there are many different types of batteries, the basic concept by which they function remains the same. When a device is connected to a battery, a reaction occurs that produces electrical energy.
Today Batteries are all around us. The modern world is dependent on these portable sources of energy, which are found in everything from mobile devices to hearing aids to cars.
