  2. Battery terminal - Wikipedia

    en.wikipedia.org/wiki/Battery_terminal

    positive on left and negative on the right corner; negative on the left and positive on the right corner. Terminals can also be both on the long or short side of the battery, or diagonally opposed, or in the middle. Purchasing the wrong configuration may prevent battery cables from reaching the battery terminals.

  3. 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 ...

  4. Lithium nickel cobalt aluminium oxides - Wikipedia

    en.wikipedia.org/wiki/Lithium_nickel_cobalt...

    The lithium nickel cobalt aluminium oxides (abbreviated as Li-NCA, LNCA, or NCA) are a group of mixed metal oxides. Some of them are important due to their application in lithium ion batteries. NCAs are used as active material in the positive electrode (which is the cathode when the battery is discharged). NCAs are composed of the cations of ...

  5. 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 ...

  6. Lead-acid battery - Wikipedia

    en.wikipedia.org/wiki/Lead-acid_battery

    Charge temperature interval. Min. −35°C, max. 45°C. 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.

  7. Maximum power transfer theorem - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_transfer_theorem

    Simplified model for powering a load with resistance R L by a source with voltage V S and resistance R S.. The theorem was originally misunderstood (notably by Joule [4]) to imply that a system consisting of an electric motor driven by a battery could not be more than 50% efficient, since the power dissipated as heat in the battery would always be equal to the power delivered to the motor when ...

  8. Nickel–iron battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–iron_battery

    The nickel–iron battery (NiFe battery) is a rechargeable battery having nickel (III) oxide-hydroxide positive plates and iron negative plates, with an electrolyte of potassium hydroxide. The active materials are held in nickel-plated steel tubes or perforated pockets. It is a very robust battery which is tolerant of abuse, (overcharge ...

  9. Nickel–cadmium battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–cadmium_battery

    In the United States, the expected battery recycling cost (to be used for proper disposal at the end of the service lifetime) is rolled into the battery purchase price. Under the so-called "batteries directive" ( 2006/66/EC ), the sale of consumer Ni–Cd batteries has now been banned within the European Union except for medical use; alarm ...
