An old engraving of Daniell’s battery cell of 1836. It is from a book of the 1890s on discoveries and inventions during the 1800s. The cell is a type of electrochemical cell invented in 1836 by John Frederic Daniell (1790–1845), a British chemist and meteorologist, and consists of a copper pot filled with a copper sulphate solution, in which is immersed an unglazed earthenware container filled with sulphuric acid and a zinc electrode (a single cell is shown left, the battery right). It was a great improvement over the existing technology.

He was searching for a way to eliminate the hydrogen bubble problem found in the voltaic pile, and his solution was to use a second electrolyte to consume the hydrogen produced by the first. The cell was a great improvement over the existing technology used in the early days of battery development. The Daniell cell is also the historical basis for the contemporary definition of the volt, which is the unit of electromotive force in the International System of Units.
