  2. Lead-acid battery - Wikipedia

    en.wikipedia.org/wiki/Lead-acid_battery

    The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.

  3. Galvanic cell - Wikipedia

    en.wikipedia.org/wiki/Galvanic_cell

    Galvanic cell. Galvanic cell with no cation flow. A galvanic cell or voltaic cell, named after the scientists Luigi Galvani and Alessandro Volta, respectively, is an electrochemical cell in which an electric current is generated from spontaneous oxidation–reduction reactions. A common apparatus generally consists of two different metals, each ...

  4. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    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 that will ...

  5. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    For batteries that power electric vehicles, see Electric vehicle battery. A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the ...

  6. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    A secondary cell produces current by reversible chemical reactions (ex. lead-acid battery car battery) and is rechargeable. Lead-acid batteries are used in an automobile to start an engine and to operate the car's electrical accessories when the engine is not running. The alternator, once the car is running, recharges the battery.

  7. Electrochemistry - Wikipedia

    en.wikipedia.org/wiki/Electrochemistry

    The leadacid battery was the first practical secondary (rechargeable) battery that could have its capacity replenished from an external source. The electrochemical reaction that produced current was (to a useful degree) reversible, allowing electrical energy and chemical energy to be interchanged as needed.

  8. Flow battery - Wikipedia

    en.wikipedia.org/wiki/Flow_battery

    A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes. [1]A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane.

  9. Alkaline battery - Wikipedia

    en.wikipedia.org/wiki/Alkaline_battery

    An alkaline battery (IEC code: L) is a type of primary battery where the electrolyte (most commonly potassium hydroxide) has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide. Compared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline ...
