Electrolytes and ionic conduction make batteries work
The batteries used to power watches, flashlights, and cars all rely on electrolytes to function. The first battery was developed by the Italian scientist Alessandro Volta (1745–1827), who also invented
and gave his name to the measurement of the force of a current, called voltageAlso called potential difference; a measurement of the amount of electric energy stored in a mass of electric charges compared to the energy stored in some other mass of charges. The common unit of measure is the volt.. Volta discovered that a weak electric current is created when two different metals (he used copper and zinc) are pressed together, separated only by a thin layer of electrolyte-soaked fabric. The electrolyte between the metals carries free electrons from one to the other, creating an...
