· Li4 Mn4 O4 F8

Li₄Mn₄O₄F₈ is a mixed-valence lithium manganese fluoride oxide compound that functions as a semiconductor, belonging to the family of layered lithium-transition metal fluorides under active research for energy storage applications. This material is currently investigated in academic and industrial research contexts as a potential cathode or electrolyte component for advanced lithium-ion and solid-state batteries, where fluorine substitution offers enhanced electrochemical stability and ionic conductivity compared to conventional oxide-based systems. The combination of manganese redox activity with fluoride's high electronegativity makes it a candidate for next-generation high-voltage or high-capacity battery architectures, though it remains largely in the development stage rather than established commercial production.

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.
