Li2O2

Lithium peroxide (Li2O2) is an inorganic ceramic compound belonging to the lithium oxide family, characterized by a peroxide ion structure that distinguishes it from simple lithium oxides. This material is primarily of research and development interest rather than established industrial production, with applications centered on advanced energy storage and oxygen generation systems where its chemical reactivity and lithium content are leveraged. Li2O2 is notable in lithium-air battery research as a discharge product that forms on cathodes, and in aerospace applications for chemical oxygen generation systems, where its decomposition under heat or catalysis releases oxygen; engineers consider it where conventional inert ceramics prove insufficient and where the material's reactivity becomes functionally beneficial rather than problematic.
