Lithium has a very low density (0.534 g/cm 3), comparable with pine wood. ... At 20 mg lithium per kg of Earth's crust, [53] lithium is the 31st most abundant element.
Prices of lithium-ion batteries have fallen over time. Overall, between 1991 and 2018, prices for all types of lithium-ion cells (in dollars per kWh) fell approximately 97%. [79] Over the same time period, energy density more than tripled. [79] Efforts to increase energy density contributed significantly to cost reduction. [83]
Lithium-ion battery Curve of price and capacity of lithium-ion batteries over time; the price of these batteries declined by 97% in three decades. Lithium is the alkali metal with lowest density and with the greatest electrochemical potential and energy-to-weight ratio .

Nova Centauri 2013 is the first in which evidence of lithium has been found. [13] 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 ...
Growing demand has caused the price of lithium carbonate to nearly double this year alone, and the IEA projects demand to grow by 40 times in the next two decades, with a majority of that supply ...
Lithium-rich clays are the third major source of lithium, although they are far less abundant than salt brines and hard-rock ores containing lithium. To be exact, lithium-rich clays make up less than 2% of the world's lithium products. [16] For comparison, brine extraction represents 39% and hard-rock ores represent 59% of the lithium ...
In 1862, the physicist William Thomson, 1st Baron Kelvin published calculations that fixed the age of Earth at between 20 million and 400 million years. [19] [20] He assumed that Earth had formed as a completely molten object, and determined the amount of time it would take for the near-surface temperature gradient to decrease to its present value.
