  2. Primary battery - Wikipedia

    en.wikipedia.org/wiki/Primary_battery

    A primary battery or primary cell is a battery (a galvanic cell) that is designed to be used once and discarded, and it is not rechargeable unlike a secondary cell (rechargeable battery). In general, the electrochemical reaction occurring in the cell is not reversible, rendering the cell unrechargeable.

  3. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    A battery explosion is generally caused by misuse or malfunction, such as attempting to recharge a primary (non-rechargeable) battery, or a short circuit. When a battery is recharged at an excessive rate, an explosive gas mixture of hydrogen and oxygen may be produced faster than it can escape from within the battery (e.g. through a built-in ...

  4. Leclanché cell - Wikipedia

    en.wikipedia.org/wiki/Leclanché_cell

    A 1919 illustration of a Leclanché cell. The Leclanché cell is a battery invented and patented by the French scientist Georges Leclanché in 1866. [1] [2] [3] The battery contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide (oxidizer), and an anode (negative terminal) of zinc (reductant).

  5. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    Primary cells are made in a range of standard sizes to power small household appliances such as flashlights and portable radios. [citation needed] As chemical reactions proceed in a primary cell, the battery uses up the chemicals that generate the power; when they are gone, the battery stops producing electricity. [citation needed]

  6. Aluminium–air battery - Wikipedia

    en.wikipedia.org/wiki/Aluminium–air_battery

    Aluminium–air batteries are primary cells, i.e., non-rechargeable. Once the aluminium anode is consumed by its reaction with atmospheric oxygen at a cathode immersed in a water-based electrolyte to form hydrated aluminium oxide, the battery will no longer produce electricity. However, it is possible to mechanically recharge the battery with ...

  7. Bunsen cell - Wikipedia

    en.wikipedia.org/wiki/Bunsen_cell

    The Bunsen cell generates about 1.9 volts which arises from the following reaction: [1]. Zn + H 2 SO 4 + 2 HNO 3 ⇌ ZnSO 4 + 2 H 2 O + 2 NO 2 (g). According to the reaction above, when 1 mole (or part) each of zinc and sulfuric acid react with 2 moles (or parts) of nitric acid, the resultant products formed are, 1 mole (or part) of zinc sulfate and 2 moles (or parts) each of water and ...

  8. Lemon battery - Wikipedia

    en.wikipedia.org/wiki/Lemon_battery

    A lemon battery is a simple battery often made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon and connected by wires. Power generated by reaction of the metals is used to power a small device such as a light-emitting diode (LED).

  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 .
