When was the battery invented?

One of the most important discoveries in the last 400 years has been electricity. You may ask, "Has electricity been around that long?" The answer is "yes" and perhaps much longer. Surprisingly, electricity only became useful to humanity in the late 1800s.

Figure 1: Prehistory batteries
Earthenware with an iron rod surrounded by copper cylinder. When filled with vinegar + electrolyte solution produces 1.1 V DC (c. 250 BC to 640 ADO).
It is believed that the Parthians who ruled Baghdad (circa 250 BC) used batteries to galvanize silver.
The Egyptians said that antimony, copper, galvanized more than 4300 years ago.

Older methods of generating electricity were by creating a static charge. Alessandro Volta (1745-1827) invented the so-called "electric pistol" by which an electric wire was placed in a container filled with methane gas. By sending a spark electrical cable through the boat would explode.

Volta then thought of using this invention is to provide long distance communications, if only a bit of Boole. An iron wire supported by wooden poles was to be hung from Como and Milan in Italy. On the receiving end, the wire end in a jar filled with methane gas. The command, an electrical spark is sent by wire that could cause a detonation to signal a coded event. This communication link ever was built.

In 1800, Alessandro Volta invented the first modern electric battery.
Volta showed that electrical current is generated when metals and chemicals come into contact.

The next stage of generating electricity through electrolysis. Volta discovered in 1800 that a continuous flow of electrical force was possible when using certain fluids as conductors to promote a reaction metal chemistry. Volta discovered further that the voltage increase when stacked photovoltaic cells. This led to the invention of the battery.
The availability of a battery, the experiments are not limited to a brief presentation of sparks that lasted a split second. An endless flow of electric current available.

In early 1800, France was approaching the height of scientific advances and new ideas were welcomed with open arms to support the political agenda. By invitation, Volta addressed the Institute of France in a series of lectures in which Napoleon Bonaparte was present. Napoleon himself helped with the experiments, drawing sparks from the battery, melting a steel wire, discharging an electric pistol and decomposing water into its elements.

In 1802, Dr. William Cruickshank designed the first electric battery capable of mass production. Cruickshank arranged square sheets of copper soldered at their ends mixed with sheets of zinc of equal size. These sheets are placed in a rectangular wooden box that was sealed over with cement. Slots in the table of metal plates held in position. The box was filled with an electrolyte of brine, or dilute acid.

The new discoveries were made when Sir Humphry Davy electric drum set largest and most powerful in the vaults of the Royal Institution in London. He connected the battery to charcoal electrodes and produced the first electric light. The Witnesses reported that his voltaic arc lamp produced "the ascending arc of the brightest ever seen."

All batteries batteries at this time, meaning that could not be recharged. In 1859, the French physicist Gaston Plante invented the first rechargeable battery. This secondary battery was based on acid of lead, a chemical that is still used today.

The battery may be much higher. It is believed that the Parthians who ruled Baghdad (ca. 250 BC) used batteries to galvanize silver. The Egyptians said that the antimony electrolytically copper more than 4300 years ago.

The third method, and most importantly, the generation of electricity was discovered relatively late - electricity through magnetism. In 1820, André-Marie Ampère (1775-1836) had noticed that wires carrying an electric current, they were sometimes attracted to each another, while at other times rejected. In 1831, (1791-1867 Michael Faraday) demonstrated how a copper disc was able to provide a steady flow of electricity turning in a strong magnetic field. Faraday and his research team managed to generate an electrical force on end, where the movement between a coil and magnet continued.

In 1899, Waldman Jungner from Sweden invented the nickel-cadmium battery. In 1947, Neumann was able to completely seal the cell. These advances led to the sealed nickel-cadmium modern today.

Investigation of nickel-metal hydride system started in the 1970s, but the metal hydride alloys were unstable in the environment of the cell. New hydride alloys were developed in the 1980s that improved stability. Nickel Metal Hydride began shipping in the 1990s.

The first primary lithium batteries appeared in early 1970. Attempts to develop lithium batteries Rechargeable followed in the 1980s but failed due to safety concerns. Due to the inherent instability of lithium metal, especially during charging, research changed to a non-metallic lithium battery using lithium ions. Although lower energy density than lithium metal, lithium? Ion is safe, provided that certain precautions during loading and unloading. In 1991, the Sony Corporation commercialized the first lithium ion battery.

As strange and unreliable the early batteries may have been, our descendants a glance day by day technology in a way similar to how we view our predecessors' clumsy experiments of 200 years ago.
