Lithium superoxide is an unstable inorganic salt with formula Li O 2. A radical compound, it can be produced at low temperature in matrix isolation experiments, or in certain nonpolar , non-protic solvents .
Crystal structure of potassium superoxide. Lithium superoxide (LiO 2) has only been isolated in matrix isolation at 15 K. Sodium superoxide (NaO 2) is a yellow-orange solid that melts at 551.7 °C. It is made by the high-pressure oxidation of sodium peroxide. Potassium superoxide (KO 2) is a yellow solid that
In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O − 2. [1] The systematic name of the anion is dioxide(1−).The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O 2, which occurs widely in nature.

Burning lithium metal produces lithium oxide. Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen at temperatures above 100 °C: [3] 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C [3] [2] 2 Li ...
Lithium peroxide is the inorganic compound with the formula Li 2 O 2. Lithium peroxide is a white solid, and unlike most other alkali metal peroxides, it is nonhygroscopic . Because of its high oxygen:mass and oxygen:volume ratios, the solid has been used to remove CO 2 from and release O 2 to the atmosphere in spacecraft .

Suboxides are a class of oxides wherein the electropositive element is in excess relative to the “normal” oxides. [1] When the electropositive element is a metal, the compounds are sometimes referred to as “metal-rich”.
