History of the battery

Porous pot cell The porous pot version of the Daniell cell was invented by John Dancer, a Liverpool instrument maker, in 1838 consists of a central zinc anode dipped into a porous earthenware pot containing a zinc sulfate solution. The porous pot is, in turn, immersed in a solution of copper sulfate contained in a copper can, which acts as the cell''s cathode.
