Useful:

• Chemical Classes: Metals -> Peroxides, Metal
• Canonical SMILES: [Li+].[Li+].[O-][O-]
• Uses: Lithium peroxide is used in air purifiers. It is also used to produce high-purity oxygen. It acts as a catalyst for polymerization of styrene to polystyrene. Further, it serves as a curing agent for special polymers and a source of oxygen in sealed spaces such as submarines and in breathing apparatus. At this time no important industrial uses of lithium peroxide are known. One interesting potential application is in the field of atmosphere regeneration for undersea and space applications, since the compound reacts with carbon dioxide to release oxygen: Li2O2+C02 -> Li2CO3 + 0.5O2.
