BU-101: When Was the Battery Invented?

Explore the earliest forms of batteries and the arrival of electricity.

One of the most remarkable and novel discoveries in the last 400 years was electricity. We might ask, “Has electricity been around that long?” The answer is yes, and perhaps much longer. Its practical use has only been at our disposal since the mid to late 1800s, and in a limited way at first. Some of the earliest public works gaining attention were streets lights in Berlin in 1882, lighting up the Chicago World’s Fair in 1893 with 250,000 light bulbs, and illuminating a bridge over the river Seine during the Paris 1900 World Fair.

The use of electricity may go back further. While constructing a railway in 1936 near Baghdad, workers uncovered what appeared to be a prehistoric battery, also known as the Parthian Battery. The object dates back to the Parthian empire and is believed to be 2,000 years old. The battery consisted of a clay jar that was filled with a vinegar solution into which an iron rod surrounded by a copper cylinder was inserted. This device produced 1.1 to 2.0 volts of electricity. Figure 1 illustrates the Parthian Battery.

A clay jar of a prehistoric battery holds an iron rod surrounded by a copper cylinder. When filled with vinegar or electrolytic solution, the jar produces 1.1 to 2 volts.


Not all scientists accept the Parthian Battery as a source of energy. It is possible that the device was used for electroplating, adding a layer of gold or other precious metals to a surface. The Egyptians are said to have electroplated antimony onto copper over 4,300 years ago. Archeological evidence suggests the Babylonians were the first to discover and employ a galvanic technique in the manufacturing of jewelry by using an electrolyte based on grape juice to gold-plate stoneware. The Parthians, who ruled Baghdad (ca. 250 BC), may have used batteries to electroplate silver.

ne of the earliest methods to generate electricity in modern times was by creating a static charge. In 1660, Otto von Guericke constructed an electrical machine using a large sulfur globe which, when rubbed and turned, attracted feathers and small pieces of paper. Guericke was able to prove that the sparks generated were electrical in nature.

In 1744, Ewald Georg von Kleist developed the Leyden jar that stored static charge in a glass jar that was lined with metallic foil on the inside and outside of the container. Many scientists, including Peter van Musschenbroek, professor at Leiden, the Netherlands, thought that electricity resembled a fluid that could be captured in a bottle. They did not know that the two metallic foils formed a capacitor. When charged up with high voltage, the Leyden jar gave the gentlemen an unexplainable hefty shock when they touched the metallic foil.

The first practical use of static electricity was the “electric pistol” that Alessandro Volta (1745–1827) invented. He thought of providing long-distance communications, albeit only one Boolean bit. An iron wire supported by wooden poles was to be strung from Como to Milan, Italy. At the receiving end, the wire would terminate in a jar filled with methane gas. To signal a coded event, an electrical spark would be sent by wire to detonate the jar. This communications link was never built. Figure 1-2 shows a pencil rendering of Alessandro Volta.

In 1791, while working at Bologna University, Luigi Galvani discovered that the muscle of a frog would contract when touched by a metallic object. This phenomenon became known as animal electricity. Prompted by these experiments, Volta initiated a series of experiments using zinc, lead, tin and iron as positive plates (cathode); and copper, silver, gold and graphite as negative plates (anode). The interest in galvanic electricity soon became widespread.

Early Batteries

Volta discovered in 1800 that certain fluids would generate a continuous flow of electrical power when used as a conductor. This discovery led to the invention of the first voltaic cell, more commonly known as battery. Volta learned further that the voltage would increase when voltaic cells were stacked on top of each other. Figure 3 illustrates such a series connection.

.Silver and zinc electrodes are connected in series, separated by paper soaked with electrolyte.

Figure 3: Volta’s experiments with the electric battery in 1796.
Metals in a battery have different electron affinities. Volta noticed that the voltage potential of dissimilar metals became stronger the farther apart the affinity numbers moved.
The first number in the metals listed below demonstrates the affinity to attract electrons; the second is the oxidation state.

Zinc = 1.6 / -0.76 V
Lead = 1.9 / -0.13 V
Tin = 1.8 / -1.07 V
Iron = 1.8 / -0.04 V
Copper = 1.9 / 0.159 V
Silver = 1.9 / 1.98 V
Gold = 2.4 / 1.83 V
Carbon = 2.5 / 0.13 V

The metals determine the battery voltage; they were separated with moist paper soaked in salt water.

In the same year, Volta released his discovery of a continuous source of electricity to the Royal Society of London. No longer were experiments limited to a brief display of sparks that lasted a fraction of a second; an endless stream of electric current now seemed possible.

France was one of the first nations to officially recognize Volta’s discoveries. This was during a time when France was approaching the height of scientific advancements. New ideas were welcomed with open arms as they helped to support of the country’s political agenda. In a series of lectures, Volta addressed the Institute of France. Napoleon Bonaparte participated in the experiments, drawing sparks from the battery, melting a steel wire, discharging an electric pistol and decomposing water into its elements (see Figure 4).

Volta’s discoveries so impressed the world that in November 1800 the Institute of France invited him to lecture at events in which Napoleon Bonaparte participated. Napoleon helped with the experiments, drawing sparks from the battery, melting a steel wire, discharging an electric pistol and decomposing water into its elements.

In 1800, Sir Humphry Davy, inventor of the miner’s safety lamp, began testing the chemical effects of electricity and found out that decomposition occurred when passing electrical current through substances. This process was later called electrolysis.

He made new discoveries by installing the world’s largest and most powerful electric battery in the vaults of the Royal Institution of London, connecting the battery to charcoal electrodes produced the first electric light. Witnesses reported that his voltaic arc lamp produced “the most brilliant ascending arch of light ever seen.”

In 1802, William Cruickshank designed the first electric battery for mass production. He arranged square sheets of copper with equal-sized sheets of zinc placed into a long rectangular wooden box and soldered together. Grooves in the box held the metal plates in position. The sealed box was then filled with an electrolyte of brine, or watered-down acid. This resembled the flooded battery that is still with us today. Figure 5 illustrates his battery workshop.

William Cruickshank, an English chemist, built a battery of electric cells by joining zinc and copper plates in a wooden box filled with an electrolyte solution. This flooded design had the advantage of not drying out with use and provided more energy than Volta’s disc arrangement.

Invention of the Rechargeable Battery

In 1836, John F. Daniell, an English chemist, developed an improved battery that produced a steadier current than earlier attempts to store electrical energy. In 1859, the French physician Gaston Planté invented the first rechargeable battery based on lead acid, a system that is still used today. Until then, all batteries were primary, meaning they could not be recharged.

In 1899, Waldmar Jungner from Sweden invented the nickel-cadmium (NiCd) battery that used nickel as the positive electrode (cathode) and cadmium as the negative (anode). High material costs compared to lead limited its use.  Two years later, Thomas Edison replaced cadmium with iron, and this battery was called nickel-iron (NiFe). Low specific energy, poor performance at low temperature and high self-discharge limited the success of the nickel-iron battery. It was not until 1932 that Schlecht and Ackermann achieved higher load currents and improved the longevity of NiCd by inventing the sintered pole plate. In 1947, Georg Neumann succeeded in sealing the cell

For many years, NiCd was the only rechargeable battery for portable applications. In the 1990s, environmentalists in Europe became concerned about the harm incurred when NiCd is carelessly disposed. The Battery Directive 2006/66/EC now restricts the sale of NiCd batteries in the European Union except for specialty industrial use for which no replacement is suitable. The alternative is nickel-metal-hydride (NiMH), a more environmentally friendly battery that is similar to NiCd.

Most research activities today revolve around improving lithium-based systems, first commercialized by Sony in 1991. Besides powering cellular phones, laptops, digital cameras, power tools and medical devices, Li-ion is also used for electric vehicles and satellites. The battery has a number of benefits, most notably its high specific energy, simple charging, low maintenance and being environmentally benign.

Electricity Through Magnetism

Generating electricity through magnetism came relatively late. In 1820, André-Marie Ampère (1775–1836) noticed that wires carrying an electric current were at times attracted to, and at other times repelled from, one another. In 1831, Michael Faraday (1791–1867) demonstrated how a copper disc provided a constant flow of electricity while revolving in a strong magnetic field. Faraday, assisting Humphry Davy and his research team, succeeded in generating an endless electrical force as long as the movement between a coil and magnet continued. This led to the invention of the electric generator, as well as the electric motor by reversing the process.

Shortly thereafter, transformers were developed that converted alternating current (AC) to any desired voltage. In 1833, Faraday established the foundation of electrochemistry on which Faraday’s law is based. It relates to electromagnetism found in transformers, inductors and many types of electrical motors and generators. Once the relationship with magnetism was understood, large generators were built to produce a steady flow of electricity. Motors followed that enabled mechanical movement and Thomas Edison’s light bulb appeared to conquer darkness.

Early electrical plants produced direct current (DC), with distribution limitations from the plant of no more than 3km (~2 miles) in distance. In around 1886, the Niagara Falls Power Company offered $100,000 for a method to transmit electricity over a long distance. When no one responded, the world’s brightest minds met in London, England. The prize was eventually given to Nikola Tesla (1856–1943), a Serbian immigrant who created the AC transmission system.


Figure 6: Nikola Tesla (1856–1943).
Serbian-American physicist, inventor and engineer best known for alternating current supply systems and rotating magnetic fields.

DC systems run on low voltage and require heavy wires; AC could be transformed to higher voltages for transmission over light wires and then reduced for use. Older folks supported DC while younger geniuses gravitated towards AC. Thomas Edison was dead set against AC, giving danger by electrocution as a reason.

The disagreement continued, but AC became the accepted norm that was also supported by Europe. George Westinghouse, an American inventor and manufacturer, began developing the Tesla system to the displeasure of Thomas Edison.

In 1883, Westinghouse created a lighting system for Niagara Falls using AC current and to everyone’s amazement lit up the Chicago World Fair in 1893 (Figure 7). Westinghouse then built three large generators to transform energy from the Niagara Falls to electricity. Three-phase AC technology developed by Tesla enabled the transmission of electric power over great distances cheaply. Electricity was thus made widely available to humanity to improve the quality of life.

Telecommunications by wire that was strung along railways operated mostly by primary batteries that needed frequent replacement. Telex, an early means to transmit data, was digital in that the batteries activated a series of relays. The price to send a message was based on the number of relay clicks required.

In the mid-1800s, telegraphy opened new careers for bright young men. Staff operating these devices moved into the growing middle class, far removed from mills and mines burdened with labor, dirt and danger. Steel magnate Andrew Carnegie recalled his early days as a telegraphy messenger: Alfred Hitchcock started his career as an estimator before becoming an illustrator.

The invention of the electronic vacuum tube in the early 1900s formed the significant next step towards high technology. It enabled frequency oscillators, signal amplifications and digital switching. This led to radio broadcasting in the 1920s and the first digital computer, called ENIAC, in 1946. The discovery of the transistor in 1947 paved the way for the arrival of the integrated circuit 10 years later, and the microprocessor that ushered in the Information Age. This forever changed the way we live and work.

Humanity has become dependent on electricity and with increased mobility, people gravitate towards portable power involving the battery. As the battery improves further, more tasks will be made possible with this portable power source.

In 1901 Thomas A. Edison brought out one of Volta’s battery designs calling it the Edison battery, that was one heck of a battery. I often wonder why we do not use it today in our solar/wind/water storage applications. It lasts forever if taken care of and it only lacks a small percentage of power when compared to a lead acid battery. I have heard stories of these batteries lasting for over a hundred years with proper maintenance. Try to get one tenth that out of any other storage device. They are no longer made in the USA, you have to go to China to get one. They are safer and more Eco friendly than lead acid. SO why?? Does anyone really know?

I know it is nice to save space and have more power, but considering how long they last and they are similar to lead acid as far a power output I wouldn’t mind putting in a few more batteries in my unit to have some last for a life time. My dad said they used them on the windmills in the early 1900s through the 1950s in the mid-west as storage batteries where people did not have electricity to run well pumps and other farming uses, houses any kind of electrical need. He said they need proper maintenance and clean electrolyte and they will last forever. They never replaced any when he was growing up so he had no idea how old they were. There is not much written about these batteries I can find as far as people using them now-a-days. Cheers all!

I forgot one important thing about why Edison was looking for a new battery. He was involved in promoting electric cars and because of the lead acid batteries spilling on the people in the car they were becoming un-popular. Using sulfuric acid is hard on skin when the batteries leaked and much worse in case of a crash, as it spilled onto the occupants. He needed a battery that did not harm people and Volta’s nickel-iron battery worked pretty well. Volta failed to patent the design and Edison did, and that we say was that.

In my reading over the years it seems poor ol’ Volta did not get credit for several of his ideas. Oh well, it sure isn’t the first time one failed to get credit for their ideas in the electrical industry. One big one come to mind: Marconi is thought to be the father of the wireless radio, when it was Nicola Tesla’s ideas that were used by Marconi to create wireless. I believe Marconi used three of Tesla’s patents in his device. I took until the 1940s to get the courts to settle that fight and Tesla won, however it was a little to late, as he passed away shortly before the decision.

Hai,This article is awesome.It was helpful.
I have a doubt regarding this by the way.I understand that salt bridge is Na2SO4 salt.When Oxidation happens, Zinc atom loses its 2 electron which goes to the external circuit and zn2+ ion will be in the zinc sulphate solution.Zinc ion reacts with SO4 2- ions from the salt bridge and the electrolyte would be neutral.Now in the cathode part Copper from copper sulphate solution combines with the 2 electrons from the anode and copper metal deposites on the cathode leaving soa 2- ions.This makes the electrolyte at cathode negative in charge.

1.What happens to SO4 2- ions,does it combine with Na2+ ions in the salt bridge turning the solution a mixture of Na2SO4 and Cu2SO4 solution?
2.Untill what condition does the redox reaction prolong,Is it untill zinc totally gets consumed or at a condition where there is no more Na2+ or SO4 2- ions in Salt bridge to balance the electolytes?

HI am not aware of any mention of a batery in my bibles. King James or NIV. No one is even sure if the device called the Bagdad battery is really a battery. After years of reading about it I’m not sure what it is myself. Good luck!

Considering the time scale we have had the electric battery I find it diff to understand why the storage cell is not more efficient and reliable if it had been as I say above perhaps we would have a much cleaner environment with less fossil fuels being spewed into the environment, No I still consider we have not placed sufficient weight upon the battery to be more reliable and cleaner for all. david bradbury

Excellent information as I am assisting an inventor of a uniquely hi-tech Battery Rejuvenator to reach investors and market.  So far the device has succeeded in converting slightly more than 30% of over 100 batteries from truly dead, and having remained disconnected from any device for up to one year, to as new, as in brand new.

Batteries will change the current world,the vehicles,the electric device…will be upsided by the most developed and innovative batteries.What I worry is the important technology mostly hold in Japan and Korea.What has Europe and America done?The best and the most forwarded technology must hold in Europe and America,because in god we trust!

Great site. A comment on terminology: cathode = negative pole; anode = positive pole. Best regards

Very informative post. But there are few corrections Anode referes to positive plate and cathode refers to negative positive plate.

Their nickel-iron batteries lasted them over 100 years? Wow. I don’t know if I should congratulate them or their batteries.

what progress is being made using aluminium. Also the advantage using Lithium over lead is weight.
