Electric voltage from a salt solution

Principle

Two electrodes in a salt solution display the most simple form of a battery. The set-up resembles basically an electrical source that generates an electrical voltage. The discovery and further development of galvanic elements, better known as batteries, is of great importance for humankind. It has enabled mobile power supply of various electrical devices, which is a big part of our today's living standard.
