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.
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 ...
Advances in battery technology—for consumer electronics and electric vehicles alike—are largely incremental, and have been since the advent of modern lithium-ion cells almost 30 years ago.
William Sturgeon built an electric motor in 1832 and invented the commutator, a ring of metal-bristled brushes which allow the spinning armature to maintain contact with the electric current and changed the alternating current to a pulsating direct current. He also improved the voltaic battery and worked on the theory of thermoelectricity.

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.
Scientists finally discovered why lithium-metal batteries fail. We always knew they’d power the EV revolution, as long as we learned why they short circuit. Scientists Find the Holy Grail: the ...
