Who invented the battery?

Volta, the Italian physicist invented the battery.

1800 volta place soaked in brine with zinc and copper scraps of paper folded into electric pile, the device can generate an electric current, later known as the voltaic pile. Voltaic also built a device that is known as the "cup crown". Put the zinc plate and the copper containing salt water or dilute acid cup, as long as the two kinds of metal plate connected with wire, there is electric current is generated. He put the device known as the "artificial electric organs", and corresponding to the natural electric eel organs. The invention of the voltaic pile, make people first get a strong and stable and constant current, laid the important material basis for the study of electricity.

Italian physicist AlessandroVolta (1745 ~ 1827) was born in como on February 18,1745.

As a student, he developed an interest in science. In 1769, volta published his work on the attraction of electricity. Resin starter was invented in 1775, and sensitive wheat straw electroscope was invented in 1781. In 1782, the relation between the capacitance C, the charge Q and the potential V of a conductor was established. Volta's major scientific contribution was the invention of the volta reactor. When he learned about galvani's experiments with "animal electricity," he set out to study the phenomenon in 1791. After a lot of experiments, he rejected the theory of "animal electricity" and put forward the "contact" theory of electricity, pointing out that galvanic electricity was generated by the contact between two different metals. On the basis of this research, he came up with the famous "volta sequence". He called metals a type 1 conductor and wet objects a type 2 conductor. If there are two types of conductors in a circuit, an electric current can be generated. In the early 1800s, he discovered a way to significantly enhance this effect, and invented the volt reactor. On March 20, 1800, he announced his invention, which caused a great sensation. It was the first device to generate a steady, continuous current, breaking new ground in electrical research. In 1801, napoleon I summoned him to Paris to perform an electric reactor experiment and awarded him a gold medal and the title of count. He was elected a foreign member of the French academy of sciences in 1803. He retired in 1819 and returned to his native cuomo. He died there on March 5, 1827.

Battery invention history

In 1780, the Italian polo that professor of anatomy at the university of galvanic (LuigiGalvani1737 on September 9, 1798 - December 4) do the frog leg muscle movement anatomy study, he found in the experiment, at the same time of the electrical discharge, if use metal knife touches frog leg nerve, frog leg muscle contraction immediately, in order to find out the reason of this phenomenon, accidentally found in further experiments, if use two metal contact frog leg tendon and muscle, respectively, when you look into the other side of the two metals, frog legs can also occur twitch. Galvani believes this is due to the presence of a "neuro-electric fluid" in the frog, which activates nerves and muscles, and the brain is an important organ for the production of this fluid.

Italian physicist v of (AlessandroVlota1745 on February 18, 1827 - March 5) in 1792 to the discovery of galvanic studied, he found that the current production does not need animal tissue, in 1793 he denies the existence of animal electricity, found that galvanic electricity produced in two different metal contact, he think the frog leg twitch is a sensitive response to the current, the current is due to two kinds of metal in the solution provided by the muscle, and constitute a loop.

In 1799, volt used copper sheet, paper soaked in brine, and zinc sheet to overlap one another and created the earliest volt reactor to obtain continuous current. In 1800 he published the principles of the battery, discovered between 1795 and 1796, and in 1801 he demonstrated the volt reactor for napoleon I, who awarded him the gold medal and made him count.

In 1803, the German chemist Gertrude made a battery.

In 1836, British chemist J. F. Daniel Daniel made the first classical galvanic cell. One disadvantage of a volt reactor is that the current decreases rapidly due to polarization. What he found was that the electrodes were separated from the zinc rods in a solution of copper sulfate using a multi-porous ceramic pot (starting with animal film). It provides a longer period of steady current than past batteries.

In 1859, the French physicist francois plante produced the first practical lead-acid battery. It consists of two spirals of lead, separated by an eraser, immersed in a solution of 10 per cent sulphuric acid, and fed with an electric current to coat one lead sheet and make the other a rough, porous surface. This battery had a higher electromotive force than any battery at the time. However, due to the complex and lengthy processing process, it is difficult to mass production, which has not been paid attention to.

1865 the first dry cell was made by a French chemist, le cronchel. He USES conductive ammonium chloride solution, zinc and graphite as electrodes and manganese dioxide as depolarizing agent. This kind of battery is inconvenient due to the use of ammonium chloride solution.

1881 French chemist C. A. Fall reformed prandtl's lead battery. He avoided the forming process, and directly coated the lead plate, so that the lead battery attracted the interest of the business community, and was soon mass production, in the automotive, radio equipment, electrochemical experiment process has been applied to become an important power supply usually used.

In 1888, chemist casnier improved le kronscher's battery. He replaced the solution with wet ammonium chloride, and replaced the container with zinc peel.

The invention of the galvanic battery dates back to the late 18th century, when the Italian biologist giovanni gavani conducted his famous frog experiment and found that frog legs twitched when touched with a metal scalpel. The famous volta believed that this was caused by electrical stimulation between the metal and the tissue fluid (electrolyte solution) of the frog's legs. In 1800, volta devised what is known as a volta reactor, with zinc as the negative pole and silver as the positive pole, using saline as the electrolyte solution. In 1836, Daniel invented the world's first practical battery, which was used in early railway signal lights.

Among the items in the collection of the Iraq museum in Baghdad is a humble little pottery jar that has been hailed as the most surprising discovery in the field of archaeology. For although it is about two thousand years old, the jar resembles a battery shell, judging by all the materials it contains and its intentions.

The mysterious object was discovered in June 1936 after railway construction workers stumbled upon an ancient tomb near Baghdad. When archaeologists arrived, they discovered that the mausoleum was in fact part of a settlement during the rest of the world (about 250 bc-ad 250). After excavating, they unearthed a large number of objects, including bricks, pottery, glass and metal products with carved patterns, plus an unusual material inside -- a closed copper pipe, an iron bar and some asphalt fragments in the oval pottery pot.

During a visit to Baghdad, physicist walter winton of London's science museum was impressed when he heard reports of the discovery. "Put some acid in a copper container, whatever, vinegar will do," he said. Hey, in the blink of an eye, you have a simple cavity that generates voltage and releases current. In series, these cavities form a battery pack that generates enough current to ring an electric bell, light a bulb, or power a small electric car.

Winton noted that the fact that the item was indeed a battery was "obvious and completely believable." His only problem was its peculiar nature. Archaeological "one-off" remains the most difficult discovery to explain. Other POTS had been found in the ancient resting place of taixifeng, near Baghdad, but winton did not know about them. The POTS were found with a variety of mysterious objects, such as amulets. This suggests that the alchemists used the POTS, but we still have no clue what they were used for. Ideally, winton said, the pot would be found along with the wire, and it would be better to find a series of such POTS because they would remove any doubt. But, as winton pointed out in 1967, if it weren't a battery, what would it be? "I'm not an archaeologist, so I came up with the easiest scientific answer. I don't see any other use for it. There may be a better answer, but I haven't heard it yet.

Twenty-five years later, no one has come up with a credible alternative explanation for the mysterious pot. And the first fact remains: it works pretty well as a battery. Two separate experiments have been conducted in the United States testing POTS and replicas of the contents. You can also use acetic acid, sulfuric acid or citric acid as electrolytes and inject them into copper tubes. The model generates a voltage of 1.5 volts, which disappears after 18 days.
