A voltaic pile, the first chemical battery. Batteries provided the main source of electricity before the development of electric generators and electrical grids around the end of the 19th century. Successive improvements in battery technology facilitated major electrical advances, from early scientific studies to the rise of telegraphs and telephones, eventually leading to portable computers ...

1881—J.A. Thiebaut patented the first battery with both the negative electrode and porous pot placed in a zinc cup. 1881—Carl Gassner invented the first commercially successful dry cell battery (zinc-carbon cell). 1899—Waldmar Jungner invented the first nickel-cadmium rechargeable battery.

It originated as a schematic drawing of the earliest type of battery, the voltaic pile. An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices.
