· JVASP-94345· LiO2

Lithium peroxide (LiO₂) is an inorganic ceramic compound belonging to the lithium oxide family, characterized by its ionic crystal structure and oxidizing properties. This material is primarily investigated in research contexts for energy storage and oxygen generation applications, particularly in advanced battery systems and aerospace life support technologies where its high energy density and oxygen-releasing capability offer potential advantages over conventional materials. Its use remains largely experimental and specialized, with development focused on next-generation lithium-air batteries and closed-loop environmental control systems in spacecraft.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
