About Li2Mn3WO8
Li2Mn3WO8 belongs to the class of layered lithium transition-metal oxides, characterized by its semiconducting electronic nature. As a metastable compound, it represents a complex structural arrangement of lithium, manganese, and tungsten within an oxygen framework, offering unique pathways for ion mobility and redox activity.
This material is primarily investigated for its potential in next-generation electrochemical energy storage systems. Its structural flexibility and the interplay between transition metals make it a subject of interest for researchers seeking to optimize cathode performance and stability in lithium-ion battery technologies.
Key Properties
Cross-validated computational properties for Li2Mn3WO8, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
