  2. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    An electrolytic cell is an electrochemical cell in which applied electrical energy drives a non-spontaneous redox reaction. [5] A modern electrolytic cell consisting of two half reactions, two electrodes, a salt bridge, voltmeter, and a battery. They are often used to decompose chemical compounds, in a process called electrolysis.

  3. Electrolytic cell - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_cell

    An electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur. [ 1 ] : 64, 89 [ 2 ] : GL7 The external energy source is a voltage applied between the cell's two electrodes ; an anode (positively charged electrode) and a cathode (negatively ...

  4. Galvanic cell - Wikipedia

    en.wikipedia.org/wiki/Galvanic_cell

    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.

  5. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    Many types of electrochemical cells have been produced, with varying chemical processes and designs, including galvanic cells, electrolytic cells, fuel cells, flow cells and voltaic piles. [34] A wet cell battery has a liquid electrolyte. Other names are flooded cell, since the liquid covers all internal parts or vented cell, since gases ...

  6. Lemon battery - Wikipedia

    en.wikipedia.org/wiki/Lemon_battery

    From 1840 to the late 19th century, large, voltaic cells using a zinc electrode and a sulfuric acid electrolyte were widely used in the printing industry. While copper electrodes like those in lemon batteries were sometimes used, in 1840 Alfred Smee invented a refined version of this cell that used silver with a rough platinum coating instead ...

  7. Salt bridge - Wikipedia

    en.wikipedia.org/wiki/Salt_bridge

    [1] It contains an electrolyte solution, typically an inert solution, used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell. [ 1 ] [ 2 ] In short, it functions as a link connecting the anode and cathode half-cells within an electrochemical cell. [ 3 ]

  8. Overpotential - Wikipedia

    en.wikipedia.org/wiki/Overpotential

    The term is directly related to a cell's voltage efficiency. In an electrolytic cell the existence of overpotential implies that the cell requires more energy than thermodynamically expected to drive a reaction. In a galvanic cell the existence of overpotential means less energy is recovered than thermodynamics predicts.

  9. 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.
