What are batteries? What is their purpose? According to Northwestern University, “A battery can change chemical energy to electricity by putting certain chemicals in contact with each other in a specific way". Batteries utilize the electricity converted to power items such as lights, television remotes, and even cars. There are three main components of a battery, which consist of the anode, known as its negative side, the cathode, known as its positive side, and electrolytes. These segments of the battery keep the flow of electricity through the chemical means of its conversion, with the help of electrons.
The first battery was invented by the Italian physicist Alessandro Volta in the year 1800. This “Voltaic Pile “ was created using discs of copper and zinc, and wet cardboard, producing an electrical current. This was the first “wet cell battery ." Then, in 1836, John F. Daniell invented the Daniell Cell. It lasted longer than the voltaic pile, using copper sulfate and zinc sulfate. It continued to be used within homes for over one hundred years. In 1949, the Alkaline-Manganese battery developed by Lew Urry, which is what is commonly used today.1
