Na3NiO3
Na3NiO3 is a semimetallic layered oxide composed of sodium, nickel, and oxygen that is being studied for its potential use in next-generation battery technologies.
About Na3NiO3
Na3NiO3 is a member of the layered sodium transition-metal oxide family, characterized by its near-zero-gap electronic structure. This semimetallic nature makes it a subject of significant interest for researchers investigating advanced charge-transport properties in energy storage materials.
Due to its position near the thermodynamic hull, the compound is considered a viable candidate for synthesis. Its structural configuration within the layered oxide class positions it as a promising material for electrochemical applications, particularly where high sodium mobility and electronic conductivity are prioritized.
Key Properties
Cross-validated computational properties for Na3NiO3, 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.

How It Compares
Within the layered sodium transition-metal oxides class.
Within the diverse family of layered sodium transition-metal oxides, Na3NiO3 occupies a distinct niche compared to more conventional members like NaNiO2 or NaCoO2. While many of its siblings are well-established as insulating or semiconducting cathode materials, the semimetallic character of Na3NiO3 suggests a unique electronic environment that differentiates its performance profile from the more common alkali-metal oxides like NaFeO2 or Na2TiO3.
