History of the development of battery

History of the development of battery


In ancient times, human beings may have been continuously in research and testing "," Such things. That was a history of several thousand years of clay bottles in 1932 in Iraq, was found near Baghdad. It has inserted a copper cylinder in the iron - may be used to store static, but the bottle the secret may never be revealed.

Whether this clay bottle manufacturing know the ancestors of the static affair, but certainty is absolutely know that the ancient Greeks. If they know an Amber friction, we will be able to attract light objects. Aristotle (Aristotle) is also aware that things magnet, which is a strong magnetic force to attract iron and metal ores.

One day in 1780, Italy Jiepouhuajia gamma cutting Nepalese doing frog anatomy, were handed metal with a different instrument, at the same time inadvertently touch the frog's legs, frog legs twitch of a muscle immediately, as if by the current stimulation, but only with a metal instrument to touch frogs, but no such anti-on. Jia cutting Nigeria, because of this phenomenon in the animal body within a power, what he called the "biological electricity." Jia cutting Nigeria in 1791 wrote the experimental results of this paper, published in the academic community.

Jia cutting Nigeria's findings and the great physicists interested in cutting their competing flail repeat of the Nigerian experiment, an attempt to find a way currents, Italy volts at a number of experimental physicists concluded: gamma cutting Nigeria " biological, "said is not correct, the frog muscle is able to generate a current, probably some kind of liquid in the muscle is at work. To proof their point of view, volts to two different pieces of metal in a variety of Baptist solution for trials. The results showed that the two metal film, and as long as there is a solution in a chemical reaction, between the metal sheets to generate a current.

1799, volts to a zinc plate and a silver plate immersed in salt water, found two metal wire connections in the current through. Therefore, he put many silver-zinc tablets and saturated brine between the velvet pad or paper, the stack-up. Hand-to-ends, will be strong current stimulation. Volts use this method successfully made the world's first battery ─ ─ "volts stack." This "V stack" actually is a series of batteries. Electrical it became early experiments, telex machine's power source.

Italian physicist PV on the Galilean repeatedly cutting Nigerian experiment. As a physicist, his attention mainly concentrated in the two metals, rather than in the frog on the nerve. The gamma cutting Nigeria found the phenomenon of frog legs twitch, and he would like to, and this may be related, but he thought the frog muscle and nerve, there is no electricity, he seems to be the flow of electricity from two different metals mutual contacts generated, and whether the metal contacts or activities unrelated to the animal died. Experiment proves that as long as the two metal film interval with a saline solution or caustic water to soak (or even as long as it is wet and) Yingzhi, linen, leather or other cavernous things (he said that this was essential to the success of the experiment ), and metal lines to connect the two pieces of metal, with or without the frog muscle, will have an electric current through. This is a clear indication of the frog, not from the organization, the role of frog legs only equivalent to a very sensitive Electroscope it.

1836, Britain's Daniel "PV stack" of the improvement. He used to dilute sulfuric acid electrolyte, the battery polarization solve problems, not create a polarization, and to maintain the current balance ─ copper zinc batteries, also known as "Daniel battery." Later, the situation started to polarization effects better, "Ben battery" and the "Grove battery" come out. However, the battery voltage exists with the use of extended time and the problem of declining.

1860, France's lead Pulangtai do with the invention of the battery electrode. The uniqueness of this battery is that when the battery used for a period of the voltage drop, it can be to Qualcomm to reverse current of the battery voltage recovery. Because the battery can be recharged, can be used repeatedly, calling it the "battery."

However, no matter what battery takes between two metal plates liquid filling, handling very convenient, especially batteries used in liquid sulfuric acid is in a very dangerous when moving.

Also in 1860, France's Leikelanshi (GeorgeLeclanche) also invented the world wide use of the battery (carbon-zinc batteries), the predecessor. It is the negative zinc and mercury alloy rods (zinc - prototype battery voltage anode, the negative electrode materials proved to be as one of the best metal), and its cathode is a porous glass with crushed costumes Dioxide manganese and carbon mixture. Here is a mixture of carbon rod inserted as current collector. Cathode and anode rod Cup has been immersed in the electrolyte as ammonium chloride solution. This system is known as the "wet batteries." Leikelanshi Although simple battery manufacturers but cheaper, so until 1880才被improved "batteries". % Zinc anode can be improved (that is, battery shell), rather than liquid electrolyte into a paste, which is now basically we are familiar with the carbon-zinc battery.

1887, the British invented the earliest Heleisen notebook batteries. Batteries for the electrolyte paste, the spill will not be easy to carry, so access to a wide range of applications.
