About Li2MnVO4
Li2MnVO4 is a complex layered lithium transition-metal oxide characterized by its semiconducting electronic nature. As a metastable phase, it represents an intriguing subject for researchers investigating structural variations within lithium-based oxide systems. Its unique elemental composition of lithium, manganese, vanadium, and oxygen positions it as a candidate for exploring ion mobility and electrochemical performance in next-generation battery architectures. The material's metastability suggests that its synthesis and structural integrity are highly sensitive to processing conditions, making it a focal point for studies on phase stability and structural evolution in solid-state chemistry.
Key Properties
Cross-validated computational properties for Li2MnVO4, 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.
