  2. Aluminium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Aluminium-ion_battery

    The amount of energy or power that a battery can release is dependent on factors including the battery cell's voltage, capacity and chemical composition. A battery can maximize its energy output levels by: Increasing chemical potential difference between the two electrodes [9] Reducing the mass of reactants [9]

    Thus converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. [3]

  6. Open-circuit voltage - Wikipedia

    en.wikipedia.org/wiki/Open-circuit_voltage

    The box is any two-terminal device, such as a battery or solar cell. The two terminals are not connected to anything (an open circuit), so no current can flow into or out of either terminal. The voltage v oc between the terminals is the open-circuit voltage of the device.

  7. Solid-state electrolyte - Wikipedia

    en.wikipedia.org/wiki/Solid-state_electrolyte

    The use of a high capacity anode and low reduction potential, like lithium with a specific capacity of 3860 mAh g −1 and a reduction potential of -3.04 V vs SHE, in substitution of the traditional low capacity graphite, which exhibits a theoretical capacity of 372 mAh g −1 in its fully lithiated state of LiC 6, [4] is the first step in the ...

  8. 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.

  9. Nanobatteries - Wikipedia

    en.wikipedia.org/wiki/Nanobatteries

    While many other types of batteries exist, current battery technology is based on lithium-ion intercalation technology for its high power and energy densities, long cycle life and no memory effects. These characteristics have led lithium-ion batteries to be preferred over other battery types. [ 8 ]
