About Li2Mn3NbO8
Li2Mn3NbO8 is a complex layered lithium transition-metal oxide that exhibits semiconducting electronic behavior. Its structural arrangement and thermodynamic proximity to the stability hull make it a significant subject for researchers investigating new electrode materials for high-performance energy storage systems.
Because it is considered likely synthesizable, this compound serves as a valuable model for understanding how niobium substitution influences the stability and electrochemical performance of manganese-based oxide frameworks. It is primarily studied for its potential to improve the cycling stability and capacity retention of next-generation batteries.
Key Properties
Cross-validated computational properties for Li2Mn3NbO8, aggregated across 4 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.
