How was the battery invented?

Imagine living in a world where nothing ran on batteries. No phones buzzing in your pocket. No remote controls, no wireless earbuds, no electric cars humming down the street. For most of human history, that was just… life. Then one day in 1800, an Italian scientist named Alessandro Volta stacked some metal discs on his lab table and accidentally created a revolution.
Before Volta, people had seen electricity do wild things — sparks from rubbing amber, lightning splitting the sky — but nobody could keep it flowing steadily. Electricity was like a sneeze: dramatic, brief, then gone. What the world needed was electricity you could turn on whenever you wanted, like water from a faucet. Volta figured out how to make that happen.
