  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. 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 ...

  4. Earth battery - Wikipedia

    en.wikipedia.org/wiki/Earth_battery

    The simplest earth batteries consist of conductive plates from different metals of the electropotential series, buried in the ground so that the soil acts as the electrolyte in a voltaic cell. As such, the device acts as a primary cell. When operated only as electrolytic devices, the devices were not continuously reliable, owing to drought ...

  5. 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 ...

  7. Zinc–carbon battery - Wikipedia

    en.wikipedia.org/wiki/Zinc–carbon_battery

    The zinc-chloride cell, frequently referred to as a heavy-duty, extra-heavy-duty, super-heavy-duty, or super-extra-heavy-duty battery, is an improvement on the original zinc–carbon cell, using purer chemicals and giving a longer service life and steadier voltage output as it is used and offering about twice the service life of general-purpose ...

  8. Alkaline battery - Wikipedia

    en.wikipedia.org/wiki/Alkaline_battery

    When alkaline batteries were introduced in the late 1960s, their zinc electrodes (in common with the then ubiquitous carbon-zinc cells) had a surface film of mercury amalgam. Its purpose was to control electrolytic action on impurities in the zinc; that unwanted electrolytic action would reduce shelf life and promote leakage. When reductions in ...

  9. 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] It also maintains electrical ...
