  2. Lithium - Wikipedia

    en.wikipedia.org/wiki/Lithium

    At 20 mg lithium per kg of Earth's crust, [53] lithium is the 31st most abundant element. [54] According to the Handbook of Lithium and Natural Calcium, "Lithium is a comparatively rare element, although it is found in many rocks and some brines, but always in very low concentrations. There are a fairly large number of both lithium mineral and ...

  3. Lithium cycle - Wikipedia

    en.wikipedia.org/wiki/Lithium_cycle

    Lithium can be removed from solution by formation of secondary minerals like clays, oxides, or zeolites. [1] Rivers eventually feed into the ocean, providing approximately 50% of marine inputs. [2] The remainder of lithium inputs come from hydrothermal venting at mid-ocean ridges, where lithium is released from the mantle. [1]

  4. Cosmological lithium problem - Wikipedia

    en.wikipedia.org/wiki/Cosmological_lithium_problem

    Lithium is also found in brown dwarf substellar objects and certain anomalous metal-poor stars. Because lithium is present in cooler, less massive brown dwarfs, but is destroyed in hotter red dwarf stars, its presence in the stars' spectra can be used in the "lithium test" to differentiate the two, as both are smaller than the Sun. [11] [12] [14]

  5. Lithosphere - Wikipedia

    en.wikipedia.org/wiki/Lithosphere

    The tectonic plates of the lithosphere on Earth Earth cutaway from center to surface, the lithosphere comprising the crust and lithospheric mantle (detail not to scale). A lithosphere (from Ancient Greek λίθος (líthos) 'rocky' and σφαίρα (sphaíra) 'sphere') is the rigid, [1] outermost rocky shell of a terrestrial planet or natural satellite.

    Based on the principle of relativity, Henri Poincaré (1905, 1906), Hermann Minkowski (1908), and Arnold Sommerfeld (1910) tried to modify Newton's theory and to establish a Lorentz invariant gravitational law, in which the speed of gravity is that of light. As in Lorentz's model, the value for the perihelion advance of Mercury was much too low.

  7. Big Bang nucleosynthesis - Wikipedia

    en.wikipedia.org/wiki/Big_Bang_nucleosynthesis

    This discrepancy, called the "cosmological lithium problem", is considered a problem for the original models, [16] that have resulted in revised calculations of the standard BBN based on new nuclear data, and to various reevaluation proposals for primordial proton–proton nuclear reactions, especially the abundances of 7 Be + n → 7 Li + p ...

  9. History of the battery - Wikipedia

    en.wikipedia.org/wiki/History_of_the_battery

    Unlike lithium-ion batteries, which use liquid or gel electrolytes, solid-state batteries utilize solid electrolytes. This key difference enhances safety, as solid electrolytes are less likely to catch fire or leak. Solid state batteries can also achieve higher energy densities, therefore lasting longer than traditional lithium-based batteries ...
