About Mn5O8
Mn5O8 is a semiconducting binary oxide that functions as a conversion anode material. Its structural complexity and near-hull thermodynamic stability make it a subject of significant interest for researchers investigating alternative electrode chemistries for high-capacity energy storage systems. The material is characterized by a rich structural landscape, with numerous reported configurations across multiple databases, indicating a versatile framework for electrochemical activity. As a conversion oxide, it relies on the complete transformation of its metal-oxygen bonds during cycling to store charge, offering a pathway toward higher energy densities compared to traditional intercalation materials.
Key Properties
Cross-validated computational properties for Mn5O8, 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.
