Electric power sends energy through a circuit to power an electrical device. A battery may be spent after it delivers its energy, or we may be able to refresh it. Much of modern society might not have evolved the way it did without this magical device. Did Volta make the first battery, or was it someone else? Let’s find out.
Who Made the First Battery: Was It Volta?
The answer to this question depends on what we consider a battery to be. That piece of the puzzle is simple. A battery has a positive cathode terminal, and a companion negative anode one.
The negative anode stores the energy. But this energy must flow across to the cathode through an electrolyte before it can leave the battery. The device that Alessandro Volta invented in 1800 meets those basic criteria.
His voltaic pile contained pairs of alternating zinc and copper discs, between which energy flowed through pieces of cloth soaked in salty water. Volta definitely made a pioneering battery. But was it the first one?
What If the Leyden Jar Was the First Battery?
This is where the story gets interesting. Two men, Ewald von Kleist and Pieter van Musschenbroek came up with the same idea in 1745, working independently.
Their invention was a glass jar with a lid, and a metal foil terminal cemented to the inside and the outside. A separate metal terminal projected vertically through the lid, while contacting the metal foil. The current flowed if the jar contained water.
This device that we now call the leyden jar released the energy it stored in one single quick burst. Therefore,we have to agree that Volta made the first battery. This is because his pile delivered a flow of energy.
One Was a Battery. The Other Was a Capacitor
Volta’s device was the first battery, because a static electrical charge flowed from it. The Leyden Jar was the first capacitor, because it stored electrostatic energy in an electrical field.
Both devices exist side by side in our world of electricity storage.The big difference is batteries deliver greater energy density, while capacitors charge and discharge much faster.
