The inventor of the battery

Leiden bottle In the eighteenth century, four, in the 1950s, power generation equipment to improve the atmosphere and study the phenomenon of electricity, a physicist who has attracted wide interest, in 1745, Kleist's Prussia lead to the use of electricity from the friction primer To the nail with glass bottles. When he hit his hand nails, PowerShot S230 come under severe blow. May be found in this inspired, masenbrok the University of Leiden in 1746 invented the charge of the collection, "Leiden bottle." Because he is hard to see the collection of electricity is very easy to disappear gradually in the air, he would like to find a way to save electricity. One day, he used a barrel hanging in the air, PowerShot S100 starting with the motor attached barrel, PowerShot S200 and the other with a rise in copper wire from the barrel, PowerShot S400 an immersion filled with a water bottle, he let an aide to a Glass bottles of hand,masenbrok hard rock from the side in the motor. Then his assistant will be careless in one hand and hit the barrel, he suddenly felt a strong electric shock, crying again.masenbrok assistant and then exchanged with me from shaking assistant motor, he Shuiping Zi one hand, one hand touch the barrel. In the letter, he described the results: "I want to tell you a horrible experiment However, new facts, but I warn you, in any case not have to repeat the experiment. ... ... Containers on the right hand, I tried to use one hand from the charge of the iron posts on the rise Sparks. Suddenly, my hand was like a lot of strength to combat so my whole body vibration, PowerShot S410 arm and body ... ... has created a feeling of indescribable terror. In a word, I thought I would stop life. " Although masenbrok do not want to do this experiment, but he concluded: glass bottles on the body charged with electricity can be preserved. It was not clear from electricity to preserve what is the role of the bottle or PowerShot S30 bottle of water, then put it in storage bottles known as the "bottle Leiden," the experiment known as the "bottle Leiden experiment." This "electric shock" phenomenon found that well-known and greatly increase people's bottles of Leiden. masenbrok warning played a role on the contrary, it is in a much larger scale for a repeat of this experiment, this experiment in some cases it has become a game of entertainment. People used to make bottles of Leiden spark discharge to kill the rats perform, some people use it to point alcohol and PowerShot S70 , PowerShot S60 , PowerShot S50 , Canon gunpowder. One of the most spectacular time-scale demonstrations are Nolette the French in Paris before the Notre Dame. Nolette the invitation of king Louis XV's royal family members to watch on-the-spot performances. He transferred to the 700 monks and let them hand in hand and his public schedule, a total length of 900 feet, about 275 meters, which is extremely spectacular. So that in the first row of monks with their hands Leiden hold bottles, the scheduled end of monks holding a bottle of Leiden lead, then let Leiden bottle electrification, the results of 700 monks due to electric shocks jumped almost at the same time, The presence of all people was stunned. Nolette a convincing tone to explain the tremendous power of electricity. It was electric again soon for medicine, will play an electric power generated through the patient's body, ZR100 , ZR200 , ZR300 , ZR600 for the treatment of paraplegia, neuralgia, and other diseases. This treatment method has been used until people understand the role of power before it stopped. The history of the battery cell found mainly attributed to about 1800, PV will be found alessandrovolta zinc and silver piece by piece soaked in sea water or salt water separated from the paper could form a current. Volta called the stack. If a clean piece of zinc and silver respectively, with film of the upper and lower lips at the end of the saliva is also due to acid (like electrolytes) also have the output voltage, so lips will be felt through the current weak. In fact, as long as between two different metals in order to get through the electrolyte will have a different potential difference. johannritter in 1802 found that the batteries can be recharged to repeat the production. However, the original ELURA 65 , ELURA 60 , ELURA 50 , Optura 30 battery is still not ideal, through continuous improvement until 1860 or so, began to develop a modern originator of the battery. Georgeleclanchefrance first in 1860 to develop carbon-zinc batteries. This ZR700 , ZR800 battery easier to manufacture, and the first water-based wet electrolyte gradually with sticky cloud-like manner similar to replace Jiang Hu, then packed in containers, '' stem-cell emerged, which is the ancestor of 'dry'. Carbon-zinc batteries are still the most modern dry battery output in the ZR830 , ZR850 , MV800 battery. Lead battery: 1860 raymond developed lead-acid batteries, use two thin films in order to lead separate piece of rubber, and then either by immersion in diluted sulfuric acid. The initial capacity is very small, then make use of lead oxide react more quickly and more efficiently. Is still used in most car Elura 80 , ELURA 50 , ELURA 70 batteries. Also in the world accounting for 60% of battery sales. In recent years, sealed lead batteries are more convenient to use. Not only economic (cheap) and be able to adapt to different environments. Lead battery of lead oxide cathode reaction pbo2 become lead sulfate pbso4 moving in the negative reaction also lead the formation of sulfuric acid electrolyte lead pbso4 is diluted sulfuric acid.
