Lithium-ion batteries, which are rechargeable and have a high energy density, differ from lithium metal batteries, which are disposable batteries with lithium or its compounds as the anode. [ 160 ] [ 161 ] Other rechargeable batteries that use lithium include the lithium-ion polymer battery , lithium iron phosphate battery , and the nanowire ...
Lithium is especially useful, because its ions can be arranged to move between the anode and the cathode, using an intercalated lithium compound as the cathode material but without using lithium metal as the anode material. Pure lithium will instantly react with water, or even moisture in the air; the lithium in lithium-ion batteries is a less ...
The intermetallic compounds of the alkali metals with the heavier group 13 elements (aluminium, gallium, indium, and thallium), such as NaTl, are poor conductors or semiconductors, unlike the normal alloys with the preceding elements, implying that the alkali metal involved has lost an electron to the Zintl anions involved.

The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Lithium is a highly reactive alkali metal that is widely used in various industrial applications due to its unique properties. Lithium compounds are formed by combining lithium with other elements, such as oxygen , sulfur , and chlorine , to form different chemical compounds.
In 2019, the same Stanford lab developed a method for lithium-metal batteries to retain 85 percent charge after 160 cycles—a major improvement compared to the previously reported 30 percent.
A lithium atom is an atom of the chemical element lithium. Stable lithium is composed of three electrons bound by the electromagnetic force to a nucleus containing three protons along with either three or four neutrons , depending on the isotope , held together by the strong force .
ɒ n,-ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its ...
