Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. [2][3] It is named after Friedrich Paschen who discovered it empirically in 1889. [4]
The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. [1] Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy.
the fraction of the battery's capacity which is currently removed from the battery with regard to its (fully) charged state. For fully charged batteries, the depth of discharge is connected to the state of charge by the simple formula. D o D = 1 − S o C {\displaystyle \mathrm {DoD} =1-\mathrm {SoC} } The depth of discharge then is the ...
The data below tabulates standard electrode potentials (E °), in volts relative to the standard hydrogen electrode (SHE), at: Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa). Variations from these ideal conditions ...
In energy storage and fuels. For energy storage, the energy density relates the stored energy to the volume of the storage equipment, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy.

The Li‑ion can be discharged to 3 V and lower; however, with a discharge to 3.3 V (at room temperature), about 92–98% of the capacity is used. [2] Importantly, particularly in the case of lithium-ion batteries, which are used in the vast majority of portable electronics today, a voltage cut-off below 3.2 V can lead to chemical instability ...
State of charge. State of charge (SoC) quantifies the remaining capacity available in a battery at a given time and in relation to a given state of ageing. [1] It is usually expressed as percentage (0% = empty; 100% = full). An alternative form of the same measure is the depth of discharge (DoD), calculated as 1 − SoC (100% = empty; 0% = full ...
