Li4Mn5O9F
ceramic· JVASP-47298· Li4Mn5O9F
Li₄Mn₅O₉F is a mixed-valence lithium manganese oxide fluoride ceramic compound under investigation as a cathode material for lithium-ion batteries. This fluorine-substituted oxide belongs to the family of layered manganese oxides, which are attractive for energy storage applications due to their potential for high capacity and tunable electrochemical properties. The fluorine doping modifies the crystal structure and redox behavior compared to non-fluorinated analogs, making it relevant for researchers developing next-generation battery cathodes with improved cycle life, thermal stability, or cost advantages over conventional lithium transition-metal oxides.

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.
