    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 ...

  4. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    A power station, also known as a power plant or powerhouse and sometimes generating station or generating plant, is an industrial facility that generates electricity. Most power stations contain one or more generators, or spinning machines converting mechanical power into three-phase electrical power.

  5. Atomic battery - Wikipedia

    en.wikipedia.org/wiki/Atomic_battery

    Nuclear batteries began in 1913, when Henry Moseley first demonstrated a current generated by charged-particle radiation. In the 1950s and 1960s, this field of research got much attention for applications requiring long-life power sources for spacecraft. In 1954, RCA researched a small atomic battery for small radio receivers and hearing aids. [4]

    en.wikipedia.org/wiki/Dynamo

    "Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...

  7. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Wind turbines usually provide electrical generation in conjunction with other methods of producing power. Electric generators transform kinetic energy into electricity. This is the most used form for generating electricity based on Faraday's law. It can be seen experimentally by rotating a magnet within closed loops of conducting material, e.g ...

  8. Franklin's electrostatic machine - Wikipedia

    en.wikipedia.org/wiki/Franklin's_electrostatic...

    Franklin called this device an "electrical battery", [4] but that term later came to have a different meaning, referring instead to a set of one or more galvanic cells. At that time, the word "battery" was a military term for a group of cannons. [32] Franklin was the first to apply the terms "positive" and "negative" to electricity.
