Chemical Battery 1

Invention:electric battery in 1800
Volta called his battery the Voltaic Pile. He stacked alternating layers of zinc, cardboard soaked in salt water and silver, image courtesy BBC Rough Science
Function:noun / electric bat·tery
Definition: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 (or “battery”) of electro-chemical devices.

A battery, which is actually an electric cell, is a device that produces electricity from a chemical reaction. Strictly speaking, a battery consists of two or more cells connected in series or parallel, but the term is generally used for a single cell. A cell consists of a negative electrode; an electrolyte, which conducts ions; a separator, also an ion conductor; and a positive electrode.

1800 - Alessandro Volta invented the voltaic pile and discovered the first practical method of generating electricity. Constructed of alternating discs of zinc and copper with pieces of cardboard soaked in brine between the metals, the voltic pile produced electrical current. The metallic conducting arc was used to carry the electricity over a greater distance. Alessandro Volta's voltaic pile was the first "wet cell battery" that produced a reliable, steady current of electricity.
