  2. Air ioniser - Wikipedia

    en.wikipedia.org/wiki/Air_ioniser

    An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle. Cations are positive ions missing one or more electrons, resulting in ...

  3. Health and environmental effects of battery electric cars

    en.wikipedia.org/wiki/Health_and_environmental...

    Some electric vehicle manufacturers, such as Tesla, claim that a lithium-ion battery that no longer fulfills the requirements of its intended use can be serviced by them directly, thereby lengthening its first-life. [69] Reused electric vehicle batteries can potentially supply 60-100% of the grid-scale lithium-ion energy storage by 2030. [70]

  4. Negative air ions - Wikipedia

    en.wikipedia.org/wiki/Negative_air_ions

    Negative ion reaction equations. Negative air ions (NAI) are important air component, generally referring to the collections of negatively charged single gas molecules or ion clusters in the air. They play an essential role in maintaining the charge balance of the atmosphere. [1][2] The main components of air are molecular nitrogen and oxygen.

  5. Aluminium–air battery - Wikipedia

    en.wikipedia.org/wiki/Aluminium–air_battery

    Aluminium–air battery. Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes.

  6. Zinc–air battery - Wikipedia

    en.wikipedia.org/wiki/Zinc–air_battery

    A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste and form zincate (Zn ...

  7. Electric vehicle battery - Wikipedia

    en.wikipedia.org/wiki/Electric_vehicle_battery

    An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density. Compared to liquid fuels, most current battery technologies have much lower ...

  8. Electric vehicle - Wikipedia

    en.wikipedia.org/wiki/Electric_vehicle

    An electric vehicle (EV) is a vehicle whose propulsion is powered fully or mostly by electricity. [1] EVs include road and rail vehicles, electric boats and underwater vessels, electric aircraft and electric spacecraft. Early electric vehicles first came into existence in the late 19th century, when the Second Industrial Revolution brought ...

  9. Battery electric vehicle - Wikipedia

    en.wikipedia.org/wiki/Battery_electric_vehicle

    Charging point. A battery electric vehicle (BEV), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that uses energy exclusively from an on-board battery. This definition excludes hybrid electric vehicles. BEVs use electric motors and motor controllers instead of ...
