Successive improvements in battery technology facilitated major electrical advances, from early scientific studies to the rise of telegraphs and telephones, eventually leading to portable computers, mobile phones, electric cars, and many other electrical devices. Students and engineers developed several commercially important types of battery.
Alessandro Giuseppe Antonio Anastasio Volta (UK: / ˈ v ɒ l t ə /, US: / ˈ v oʊ l t ə /; Italian: [alesˈsandro ˈvɔlta]; 18 February 1745 – 5 March 1827) was an Italian chemist and physicist who was a pioneer of electricity and power, [1] [2] [3] and is credited as the inventor of the electric battery and the discoverer of methane.
French mathematician Pierre-Simon Laplace developed the Laplace transform to transform a linear differential equation into an algebraic equation. Later, his transform became a tool in circuit analysis. 1800: Italian physicist Alessandro Volta invented the battery. 1804: Thomas Young: Wave theory of light, Vision and color theory: 1808
The voltaic pile was the first electrical battery that could continuously provide an electric current to a circuit. [1] It was invented by Italian chemist Alessandro Volta , who published his experiments in 1799. [ 2 ]
2008: The launch of Tesla Roadster- the first highway legal, serial production, all-electric car to use lithium-ion battery cells, and the first production all-electric car to travel more than 244 miles (393 km) per charge- ushered a new era in the history of Li-ion batteries, which is signified as inflection points in the plots "The log number ...
The Apple II platform financially carried the company well into the Macintosh era of the late 1980s; [59] it was made semi-portable with the Apple IIc of 1984, and was extended, with some input from Wozniak, by the 16-bit Apple IIGS of 1986, and was discontinued altogether when the Apple IIe was discontinued on November 15, 1993 (although the ...
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
