The Invention of Battery Cells
Battery cells were invented in 1800 by a scientist named Alessandro Volta. He made a battery by making a stack of alternating layers of zinc, blotting paper soaked in salt water and silver (known as voltaic pile). These were connected to certain fluids as conductors. Alessandro discovered that this created a continuous flow of electrical force. He also discovered that stacking more voltaic piles on top would increase the voltage.
How Battery Cells Work:
Battery cells work by having a reaction called an electrochemical reaction. This is when electrical energy is produced to a reaction when a device is connected to the battery. Electrical charges travel along the wires, conductive liquid and voltaic piles and complete a circuit. This is how a battery cell works.
