· Li14 Mn2 O9

Li₁₄Mn₂O₉ is a lithium-manganese oxide compound belonging to the family of mixed-valence transition metal oxides, typically studied as an experimental cathode material or lithium-ion conductor in solid-state battery research. This material is primarily of interest in advanced energy storage development rather than current production applications, where it is investigated for its potential ionic conductivity and structural stability in next-generation lithium batteries and solid electrolyte systems. The manganese-lithium oxide chemistry offers a research pathway toward improving energy density and thermal stability compared to conventional layered oxide cathodes.

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.
