· Li2 Mn4 O2 F6

Li₂Mn₄O₂F₆ is a lithium manganese oxide fluoride compound, a mixed-anion ceramic semiconductor in the broader family of lithium-transition metal oxyfluorides currently under research for energy storage and electrochemical applications. This material is part of an experimental class of compounds designed to overcome limitations of conventional lithium-ion battery cathodes through structural stability and enhanced ionic conductivity achieved via fluorine doping. Engineers evaluating this material should recognize it as a research-phase compound rather than a production standard; its primary appeal lies in potential next-generation battery chemistry, where the combined oxide-fluoride framework could enable higher energy density or improved cycling performance compared to conventional layered oxides.

Export Control

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.
