Batteries produce electricity through controlled electro-chemical reactions. When the early electro-chemical battery revolution began in the 1800s, they were simple, expensive, and produced relatively little electricity.
Batteries soon transformed science and communication, by providing the first reliable source of portable electric current.
The Voltaic Pile Established The World’s First Battery
The Voltaic Pile, invented by Alessandro Volta in 1800, was the world’s first practical battery. It consisted of alternating discs of zinc and copper, separated by cloth soaked in salt water or an acid. The early electrochemical battery evolution was about to begin!
The First Controlled Source of Electro-Chemical Energy
Volta’s invention produced a steady electric current, instead of the brief sparks produced by static electricity generators. Scientists soon began using Voltaic Piles to study electricity and perform chemistry experiments.
Daniell Cell Steps Towards Greater Battery Reliability
The Daniell Cell greatly improved battery reliability in 1836. It used zinc and copper electrodes in separate electrolytes, reducing the polarization that weakened earlier batteries. The Daniell Cell delivered a stable voltage and soon became the preferred power source for telegraph networks.
The Grove Cell Generates A Higher Voltage BUT …
The Grove Cell generated a higher voltage in 1839, by teaming zinc and platinum electrodes with sulfuric and nitric acids. It was powerful but produced unpleasant fumes, restricting its use to laboratories and scientific demonstrations.
The Leclanché Cell Foundation Of Dry Cell Batteries
The Leclanché Cell introduced zinc, manganese dioxide, and an ammonium chloride electrolyte in 1866. It required little maintenance, and went on to become the foundation of the modern dry cell battery. It was widely used for electric doorbells, signalling equipment, and early telephones.
Foundations in Place For Every Portable Battery Today
Batteries powered telegraph systems, laboratory research, electroplating, medical instruments, railway signaling, and experimental electric lighting throughout the nineteenth century.
Batteries also enabled important discoveries in chemistry and physics, by providing a dependable electrical source when mains electricity was unavailable.
These early battery technologies laid the foundations for every portable battery we use today. They make much of the technology possible that we take for granted, in their own quiet way.
