An introduction to the history of the invention of batteries

His young childhood did not show the makings of a prodigy. It was not until the age of four that he talked, and his family was convinced that he was retarded. The unit of electromotive force- the driving force that moves the electric current- is now called the "volt. Aroundhe invented a wet battery called a Voltaic Pile.

An introduction to the history of the invention of batteries

The history of batteries can be traced back to Learn about the history of batteries and find out how the Daniell cell battery is constructed. Inarchaeologist Wilhelm Konig discovered some peculiar clay pots while digging at Khujut Rabu, just outside of present-day Baghdad, Iraq.

The jars, which measure approximately 5 inches Tests suggested that the vessels had once been filled with an acidic substance like vinegar or wine, leading Konig to believe that these vessels were ancient batteries.

General considerations

Since this discovery, scholars have produced replicas of the pots that are in fact capable of producing an electric charge. These "Baghdad batteries" may have been used for religious rituals, medicinal purposes, or even electroplating.

An introduction to the history of the invention of batteries

InItalian physicist Alessandro Volta created the first battery by stacking alternating layers of zinc, brine-soaked pasteboard or cloth, and silver. This arrangement, called a voltaic pile, was not the first device to create electricitybut it was the first to emit a steady, lasting current.

The height at which the layers could be stacked was limited because the weight of the pile would squeeze the brine out of the pasteboard or cloth.

The metal discs also tended to corrode quickly, shortening the life of the battery.

An introduction to the history of the invention of batteries

In this early battery, a copper plate was placed at the bottom of a glass jar and a copper sulfate solution was poured over the plate to half-fill the jar.

Then the zinc plate was hung in the jar, and a zinc sulfate solution was added. Because copper sulfate is denser than zinc sulfate, the zinc solution floated to the top of the copper solution and surrounded the zinc plate.

The wire connected to the zinc plate represented the negative terminal, while the one leading from the copper plate was the positive terminal. Obviously, this arrangement would not have functioned well in a flashlight, but for stationary applications it worked just fine.

In fact, the Daniell cell was a common way to power doorbells and telephones before electrical generation was perfected. Bythe Colombia Dry Cell became the first commercially available battery sold in the United States. Now that you know some of the history, click over to the next page to learn the various parts of a battery.The modern telephone is the result of work of many people.

Alexander Graham Bell was, however, the first to patent the telephone, as an "apparatus for transmitting vocal or other sounds telegraphically".

Bell has most often been credited as the inventor of the first practical telephone. Rechargeable Battery.

In John F. Daniell, an English chemist, developed an improved battery that produced a steadier current than Volta’s device. Until then, all batteries were primary, meaning that they could not be recharged. In , the French physician Gaston Planté invented the first rechargeable battery.

monstermanfilm.com's Telephone History Series by Tom Farle y monstermanfilm.com Heroes and Villains - A little light reading. Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many.

Dear Twitpic Community - thank you for all the wonderful photos you have taken over the years. We have now placed Twitpic in an archived state. There are endless famous (and not so famous) inventions worthy of curiosity and wonder.
