In science and technology, a battery is a device that stores energy and makes it available in an electrical form. A battery converts chemical energy into electric energy. It is a connected bunch of electro-chemical devices.

The Voltaic pile was the first modern electric battery, invented by Alessandro Volta in 1800. Volta demonstrated that when metals and chemicals come into contact with each other they produced an electrical current. In his research, Volta placed together several pairs of alternating copper and zinc discs separated by cloth and soaked the cloth in brine (salt water) to increase conductivity, and an electrical current was produced.

Alessandro Volta (1745-1827), Italian physicist, is known for his pioneering work in electricity. In 1776-77 he applied himself to chemistry, studying atmospheric electricity and devising experiments such as the ignition of gases by an electric spark in a closed vessel. In 1779 he became professor of physics at the University of Pavia, a chair he occupied for 25 years. By 1800 he had developed the so-called voltaic pile, a forerunner of the electric battery, which produced a steady stream of electricity. In honor of his work in the field of electricity, the electrical unit known as the volt was named in his honor. In honor of his work in the field of electricity, Napoleon made him a count in1810.

Alessandro Volta’s portrait appeared on Italian 10,000 lira banknote before the introduction of the euro.
