Lithium oxide (Li 2 O) or lithia is an inorganic chemical compound. It is a white solid. Although not specifically important, many materials are assessed on the basis of their Li 2 O content. For example, the Li 2 O content of the principal lithium mineral spodumene (LiAlSi 2 O 6) is 8.03%. [2]
Crystal structure of rubidium oxide. Lithium oxide (Li 2 O) is the lightest alkali metal oxide and a white solid. It melts at 1570 °C. Sodium oxide (Na 2 O) is a white solid that melts at 1132 °C and decomposes at 1950 °C. It is a component of glass. Potassium oxide (K 2 O) is a pale yellow solid that decomposes at 350 °C.
Li 2 O 2 decomposes at about 450 °C to give lithium oxide: 2 Li 2 O 2 → 2 Li 2 O + O 2. The structure of solid Li 2 O 2 has been determined by X-ray crystallography and density functional theory. The solid features eclipsed "ethane-like" Li 6 O 2 subunits with an O-O distance of around 1.5 Å. [6]
Lithium hydroxide is another important compound that is used in air purification systems, as well as in the production of lithium greases and lubricants. Lithium chloride is used as a desiccant and in the production of lithium metal, while lithium sulfate is used in the production of fertilizers and as a reagent in chemical reactions
Most lithium batteries (Li-ion) used in consumer electronics products use cathodes made of lithium compounds such as lithium cobalt oxide (LiCoO 2), lithium manganese oxide (LiMn 2 O 4), and lithium nickel oxide (LiNiO 2). The anodes are generally made of graphite. Lithium iron phosphate exists naturally in the form of the mineral triphylite ...
The LiO 2 molecule is a misnomer: the bonds between lithium and oxygen are highly ionic, with almost complete electron-transfer. [1] The force constant between the two oxygen atoms matches the constants measured for the superoxide anion (O − 2) in other contexts. The bond length for the O-O bond was determined to be 1.34 Å. Using a simple ...
It is estimated that the NCA battery pack in a Tesla Model 3 contains between 4.5 and 9.5 kg of cobalt and 11.6 kg of lithium. [4] Lithium nickel oxide LiNiO 2, which is closely related to NCA, or nickel(IV) oxide NiO 2 itself, cannot yet be used as a battery material because it is mechanically unstable, shows a rapid loss of capacity and has ...
Fully reduced lithium cobalt oxide can be prepared by heating a stoichiometric mixture of lithium carbonate Li 2 CO 3 and cobalt(II,III) oxide Co 3 O 4 or metallic cobalt at 600–800 °C, then annealing the product at 900 °C for many hours, all under an oxygen atmosphere.
