Lithium as an investment increased tendency for costlier components to be targeted for replacement by new technologies. Current projections of the global market for lithium-ion batteries range from $26 billion in 2023 ("Navigant Research") to a very optimistic $33 billion in 2019 ("Transparency Market Research"). Lithium metal is an extremely soft, highly reactive, and flammable element. It is most frequently found in deposits such as spodumene and pegmatite minerals, with larger resources in the U.S., Canada, Australia, China, Zimbabwe, and Russia. Lithium possesses a unique chemical profile making it the lightest metal in the periodic table and the least dense solid element. Its atomic
Solid of revolution Solid of revolution In mathematics, engineering, and manufacturing, a solid of revolution is a solid figure obtained by rotating a plane curve around some straight line (the "axis of revolution") that lies on the same plane. Assuming that the curve does not cross the axis, the solid's volume is equal to the length of the circle described by the figure's centroid multiplied by the figure's area (Pappus's second centroid Theorem). A representative disk is a three-dimensional volume element of a solid of revolution. The element is created by rotating a line segment (of length ) around some axis (located units
