The invention of the battery history

Source: 2020 - 04 - History 12 clicks ': the invention of the battery cell, changing shape, size, has a long tubular, square, and push button; The smallest is only 3 mm in diameter, the biggest battery array is bigger than a football field. But anyway, it is very useful. The invention of the battery also has an interesting history. Chemical battery principle of the most common chemical battery has three parts: the anode, cathode and electrolyte. The electrolyte solution many positive and negative charge. When a wire connects the anode and cathode, the chemical reaction was started. Chemical energy is converted into electrical energy. The frog and the invention of the battery and the frog, can be traced back to 1780. The story goes that Italian scientists gavani when dissecting a frog, a copper knife came across a frog leg nerve. The frog tic up immediately. This leads to a galvanic discovered the bioelectricity, is life of current or voltage, it exists in all organisms. Another Italian scientists volta repetition and tested galvani experiment, and put forward a new idea: frogs' legs is a conductor, electric current is produced by two kinds of metal copper and iron. In order to prove his point, walter did all kinds of experiment. Then he found that isolated from the cardboard soaked in brine two dissimilar metals, such as silver and zinc, will produce a constant current. This is an amazing discovery! The history of the battery. Napoleon granted him a knighthood, voltage units (in order to commemorate him, V) Named after him. From the beginning to the end voltaic cell is known as the 'wet cell, because the electrolyte solution is liquid. Accordingly, a 'dry cell' is then generated. In 1866, the French engineer le cronscher invented a new battery: zinc as the anode, manganese dioxide as cathode, ammonium chloride as the electrolyte, can provide 1. 4 volts. The battery was named le kronscher battery, is the prototype of the dry battery. Gissner improved in 1886, Germany le kronscher batteries, turn the solution into paste, wrap it as a 'dry cell with zinc, provide 1. 5 volts. Portable convenient dry cell began to rapid development, there are more than 100 members. Today, common zinc manganese dry cell is added, the kind of invention: the battery shell is made of zinc, the center of the cell is surrounded by manganese dioxide, between filling in the center of the shell and a paste made of ammonium chloride. In the past, disposable and rechargeable batteries are disposable products, run out of electricity have to throw away, this is a waste! In 1859, the French physicist plante developed a rechargeable battery. Initially, alvin fine linen to separate two lead sheet, roll up, immersed in a glass bottle filled with sulphuric acid. Then he designed 9 core ( 9) Lead-acid batteries. In 1899, Swedish scientists jung invented the rechargeable nickel cadmium battery. In Sweden in 1910. These cells more practical than lead-acid batteries, but very expensive at that time. Huge family battery is a kind of external stored energy can be converted to electricity. In addition to some of the common battery, do you know the thermoelectric battery and metal air batteries? Temperature difference between the battery, just as its name implies, is to use temperature difference, the heat directly into electricity. Temperature of battery materials generally has two kinds of metals and semiconductors. Metal air batteries is air or pure oxygen as battery anode, metal as the anode of the battery. The battery has a variety of models, such as ordinary button batteries. In addition, there are all kinds of new batteries, such as nuclear power batteries, fuel cells and biological cells. On the other hand, the solar cell is a device to convert solar energy into electrical energy. 'battery' appear in more than 2000 years ago the first battery may appear in about 250 BC. Archaeologists in the Iraqi capital Baghdad suburb found a mysterious POTS. Its basic structure and today's battery is almost the same: a thin copper cylinder, embedded in a clay jar, there is an iron bar, seal with asphalt. Is the battery? How does it work? Are you curious about? Scientists also is such. They concluded that, for the battery electrolyte is needed to work, so there is unlikely to be of sulfuric acid, so they use vinegar and wine, this is a ready-made liquid. In this way, the voltage of 1. 5 ~ 2 volts. However, scientists think it is not used as a battery, but an instrument of artisans used for electroplating gold and silver jewellery.
