About MoO5
MoO5 is a semiconducting oxide that belongs to the class of conversion anode materials. Its structural complexity is highlighted by a high number of reported configurations, reflecting significant interest in its potential electrochemical behavior within energy storage architectures. Due to its position above the thermodynamic hull, this compound is considered metastable. Its electronic properties and structural flexibility make it a subject of ongoing investigation for researchers aiming to optimize conversion-based electrode performance.
Key Properties
Cross-validated computational properties for MoO5, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of MoO5. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.

How It Compares
Within the conversion oxide anodes class.
Unlike more conventional and thermodynamically stable conversion anodes such as Fe2O3 or SnO2, MoO5 presents a distinct challenge due to its metastability. While siblings like Co3O4 and MnO2 are widely characterized for their reliable conversion pathways, MoO5 remains a more specialized member of the class, offering a unique structural profile that differentiates it from the simpler, more robust oxides in this group.
