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]
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 ...
They generally have a lower energy density than normal lithium-ion batteries. High costs and concerns about mineral extraction associated with lithium chemistry have renewed interest in sodium-ion battery development, with early electric vehicle product launches in 2023. [36]

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 ...
