Molar mass: 29.88 g/mol Appearance white solid Density: 2.013 g/cm 3: ... Lithium oxide (Li 2 O) or lithia is an inorganic chemical compound. It is a white solid.
Lithium oxide is widely used as a flux for processing silica, ... Because of its low atomic mass, it has a high charge- and power-to-weight ratio.
As an example, summing bond orders in the ammonium cation yields −4 at the nitrogen of formal charge +1, with the two numbers adding to the oxidation state of −3: The sum of oxidation states in the ion equals its charge (as it equals zero for a neutral molecule). Also in anions, the formal (ionic) charges have to be considered when nonzero.

Atomic numbers (Z) are a special case of charge numbers, referring to the charge number of an atomic nucleus, as opposed to the net charge of an atom or ion. The charge numbers for ions (and also subatomic particles ) are written in superscript, e.g., Na + is a sodium ion with charge number positive one (an electric charge of one elementary ...
The usable charge storage capacity of NCA is about 180 to 200 mAh/g. [1] This is well below the theoretical values; for LiNi 0.8 Co 0.15 Al 0.05 O 2 this is 279 mAh/g. [2] However, the capacity of NCA is significantly higher than that of alternative materials such as lithium cobalt oxide LiCoO 2 with 148 mAh/g, lithium iron phosphate LiFePO 4 with 165 mAh/g and NMC 333 LiNi 0.33 Mn 0.33 Co 0. ...
At higher (but still cryogenic) temperatures, lithium superoxide can be produced by ozonating lithium peroxide (Li 2 O 2) in freon 12: Li 2 O 2 (f 12) + 2 O 3 (g) → 2 LiO 2 (f 12) + 2 O 2 (g) The resulting product is only stable up to −35 °C. [5] Alternatively, lithium electride dissolved in anhydrous ammonia will reduce oxygen gas to ...
Lithium cobalt oxide, sometimes called lithium cobaltate [2] or lithium cobaltite, [3] is a chemical compound with formula LiCoO 2 . The cobalt atoms are formally in the +3 oxidation state, hence the IUPAC name lithium cobalt(III) oxide .
