Daniell cell
Quick Summary
The Daniell cell is a type of primary cell, an early form of battery, invented by British chemist John Frederic Daniell around 1836. It was a significant improvement over earlier voltaic cells because it provided a more constant electromotive force, approximately 1.1 volts, and maintained its power output during continuous operation.12
The cell typically consists of a copper electrode in a copper sulfate solution and a zinc electrode in dilute sulfuric acid or zinc sulfate solution. These two solutions are separated by a porous partition. This design allowed for a more stable and reliable source of electricity, which spurred further research and found various commercial applications.12
