Battery

1799

When Italian scientist Alessandro Volta made his voltaic pile in 1799 he started the journey to today’s widespread electrochemical batteries. The pile, which was a stack of silver and zinc discs separated by pieces of brine-soaked fabric, was crude but when its ends were connected via metal wire, it produced a small electric current. In the years following the pile’s invention, the battery was improved again and again, and now it is a fundamental source of portable power many of us couldn’t live without.
