Lithium peroxide is the inorganic compound with the formula Li2O2. Lithium peroxide appears as white powder, 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 CO2 and release high-purity O2 from the atmosphere in spacecraft.[4]
