Who first invented the lithium battery?

The invention of the lithium battery

"The lithium battery", is a kind of lithium metal or lithium alloy anode materials, the use of water electrolyte solution of the battery. Lithium battery is put forward in this study as early as 1912 by GilbertN. Lewis. In the 1970 s, M.S.W hittingham and began to study are put forward lithium ion batteries. Due to the lithium chemistry is very lively, making lithium metal processing, storage, use, very high demand on the environment. So lithium battery for a long time has not been applied. With the development of science and technology, the lithium battery has now become the mainstream. Lithium battery can be roughly divided into two categories: lithium battery and lithium ion batteries. Lithium ion battery does not contain lithium metal state, and can be recharged. The fifth generation of rechargeable battery product lithium battery was born in 1996, its security, specific capacity, self-discharge rate and cost performance is better than that of lithium ion batteries. Because of its high technical requirements limit, now only a few countries in the production of this kind of lithium battery.

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. Galvanic think it's a frog body there is a "neural electric fluid", this can make the nerve, muscle activity, the brain is a vital organ of the secretion of electro-hydraulic.

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.

1799 volts of copper scraps of paper, brine, zinc overlap, in turn, had created the first obtain volts of continuous current of electricity. In 1800, he published from 1795 to 1796 found that the battery principle, in 1801, he is napoleon I illustrates the volt electric pile, napoleon gave him his gold medal and named him earl.

1799, v put a piece of zinc plate and a piece of silver plate soak in salt water, found in the connection of two pieces of metal wire with an electric current passes through. So, he put many between zinc and silver strip mat saturated brine flannelette or pieces of paper, fold flat. Both ends of the touch feel intense current stimulation. V in this way successfully made the first battery in the world - "volt electric pile". The "volt electric pile" is actually in series battery pack. It became early electrical experiment, telegraph source of power.

In 1803, German chemical home, create a battery.

In 1836, the British chemist J.F.Daniel produced the first piece of classical galvanic cell. A disadvantage of the voltaic pile is due to the fast polarization effect and makes the current decreases. He found that the battery is to use more pores pottery (start with animal membrane) in electrode to separate copper and zinc in copper sulfate solution. It can battery provides for a longer time than in the past the stability of the current.

In 1859, the French physicist prandtl created the first practical lead-acid battery. He includes two roll into a spiral of lead leather, rubber off middle and immersion in 10% of the sulfuric acid solution, and then into the current, make one piece of leather plating lead, lead another piece of skin become coarse porous surface. When any battery is higher than that in the cells of the electromotive force, but due to the processing and molding process complicated and tedious, it is difficult to mass production, not taken seriously.

In 1865, the French chemist krona thanks to create the first piece of dry cell. He USES the conductive ammonium chloride solution, zinc and graphite electrode, and manganese dioxide as depolarizer. The battery brings many inconvenience due to the use of ammonium chloride solution.

French chemist in 1881 C.A. Foer reforms the prandtl lead-acid batteries. He shied away from the molding process, the coating on the lead plate directly, this makes lead battery attracted the interest of the business world, soon be batch production, in the automobile, radio equipment, has been applied in the process of electrochemical experiments, has become an important power supply usually used.

In 1888, the chemist Mr. Neil improved the crowns of the battery. He wet ammonium chloride instead of its solution, zinc and generation of container, at the same time, easy to use, has been widely applied.

The invention of the galvanic cell history can be traced back to the late 18th century, the Italian biologists galvanic were famous frog experiments, when contact with a metal blade frog legs, found that the frogs legs will twitch. Well-known voltaic thinks this is metal and frog leg tissue fluid (electrolyte solution) between the current stimulus. In 1800, volta accordingly designed the device called voltaic pile, a cathode, zinc silver anode, electrolyte solution brine. In 1836, Daniel invented the world's first practical battery, and is used to early railway signal lamp.
