Key Properties
Cross-validated computational properties for Mn2VPO7, 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.

How It Compares
Within the transition-metal phosphates class.
Within the diverse family of transition-metal phosphates, Mn2VPO7 occupies a unique space compared to well-known olivine-structured materials like LiFePO4 or LiMnPO4. While those lithium-based phosphates are primary benchmarks for battery cathodes, Mn2VPO7 represents a more complex structural arrangement that distinguishes it from simpler pyrophosphates like TiP2O7, offering a different pathway for optimizing electrochemical performance.
